For example, the window 340 may include a glass substrate or a synthetic resin film. When the window 340 is a glass substrate, the thickness of the window 340 may be 80 micrometers or less, for example, 30 micrometers, but the thickness of the window 340 is not limited thereto.

The thickness of the second upper adhesive layer 350 may be 30 micrometers to 40 micrometers, for example, 35 micrometers, but the thickness of the second upper adhesive layer 350 is not limited thereto.

In an embodiment of the present invention, the sidewall 340S of the window 340 and the sidewall 350S of the second upper adhesive layer 350 are sidewalls of other layers, for example, the sidewall 100S of the display panel 100 . and the sidewall 320S of the protective layer 320 may be disposed inside the sidewall 320S. Being disposed inside may mean that it is closer to the active area 1000A than other comparison objects.

By the folding operation of the electronic device 1000 , the positional relationship between the respective layers may be changed. According to an embodiment of the present invention, since the sidewall 340S of the window 340 is disposed inside the sidewall 100S of the display panel 100 and the sidewall 320S of the protective layer 320 , a space between the respective layers is provided. Even if the positional relationship is changed, the probability that the sidewall 340S of the window 340 protrudes from the sidewall 320S of the passivation layer 320 may be reduced. Accordingly, the possibility that an external impact is transmitted through the sidewall 340S of the window 340 may be reduced. As a result, the probability that a crack is generated in the window 340 may be reduced.

The first distance 340W between the sidewall 340S of the window 340 and the sidewall 320S of the passivation layer 320 may be greater than or equal to a predetermined distance. Here, the first distance 340W may mean a distance in a direction parallel to the first direction DR1. Also, the first distance 340W may correspond to a distance between the sidewall 340S and the sidewall 320S when viewed in a plan view.

The first distance 340W may be 180 micrometers to 205 micrometers, for example, 196 micrometers, but is not limited thereto. For example, the first distance 340W may be 50 micrometers or more, or 300 micrometers. As the first distance 340W increases, the protective layer 320 protrudes more than the window 340 , and a portion of the protective layer 320 may be bent to be attached to other components, for example, a case. In addition, as the area of the passivation layer 320 increases, the probability that a foreign material introduced from the upper portion of the passivation layer 320 will flow into the lower portion of the passivation layer 320 may be reduced.

Also, the window 340 and the second upper adhesive layer 350 may be adhered to the impact absorbing layer 370 through a lamination process. In consideration of the lamination process tolerance, the area of the window 340 and the second upper adhesive layer 350 may be smaller than the area of the impact absorbing layer 370 . Also, the area of the second upper adhesive layer 350 may be smaller than the area of the window 340 . For example, pressure may be applied to the second upper adhesive layer 350 in the process of attaching the window 340 . The second upper adhesive layer 350 may expand in a direction parallel to the first direction DR1 and the second direction DR2 under pressure. In this case, the area of the second upper adhesive layer 350 may be smaller than the area of the window 340 so that the second upper adhesive layer 350 does not protrude from the window 340 .

When the first upper adhesive layer 330 and the second upper adhesive layer 350 are attached to each other, the window 340 does not slip during a folding operation of the electronic device 1000 , so that a buckling phenomenon occurs in the window 340 . can be However, according to the embodiment of the present invention, the area of the second upper adhesive layer 350 is smaller than the area of the window 340 . Accordingly, the first upper adhesive layer 330 may not be attached to the second upper adhesive layer 350 , and a probability that a foreign material adheres to the second upper adhesive layer 350 may be reduced.

The second distance 350W between the sidewall 350S of the second upper adhesive layer 350 and the sidewall 320S of the passivation layer 320 may be greater than or equal to a predetermined distance. Here, the second distance 350W may mean a distance in a direction parallel to the first direction DR1 . Also, the second distance 350W may correspond to a distance between the sidewall 350S and the sidewall 320S when viewed in a plan view.

The second distance 350W may be 392 micrometers, but is not limited thereto. For example, the second distance 350W may be selected from a range between 292 micrometers and 492 micrometers, but is not limited thereto.

In addition, the light blocking layer 360 may be provided in a plurality of layers, and in this case, a portion is an upper surface of the impact absorbing layer 370 , and another portion is an upper surface of the protective layer 320 , a lower surface of the protective layer 320 , a window It may be provided on the upper surface of the 340 or the lower surface of the window 340 .

The impact absorbing layer 370 may be a functional layer for protecting the display panel 100 from external impact. The impact absorbing layer 370 may be selected from films having an elastic modulus of 1 GPa or more at room temperature. The impact absorbing layer 370 may be a stretched film having an optical function. For example, the impact absorbing layer 370 may be an optical axis control film. The thickness of the impact absorption layer 370 may be 35 micrometers to 45 micrometers, for example, 41 micrometers, but the thickness of the impact absorption layer 370 is not limited thereto. In an embodiment of the present invention, the impact absorbing layer 370 may be omitted.

The second hard coating layer 380 may be provided on the surface of the impact absorbing layer 370 . The impact absorbing layer 370 may include a curved surface. An upper surface of the impact absorbing layer 370 may be in contact with the second upper adhesive layer 350 . Accordingly, the curvature of the upper surface of the shock absorbing layer 370 may be filled by the second upper adhesive layer 350 . Accordingly, an optical issue may not occur on the upper surface of the impact absorbing layer 370 . A lower surface of the impact absorbing layer 370 may be planarized by the second hard coating layer 380 . That is, when the first hole 101H (refer to FIG. 4) is provided by being cut to the second adhesive layer 1020, the surface exposed by the first hole 101H (refer to FIG. 4) may have a smooth surface. Accordingly, as the second hard coating layer 380 covers the uneven surface of the impact absorbing layer 370 , haze that may be generated on the uneven surface may be prevented.

The upper member 300 may be coupled to the anti-reflection member 200 through the second adhesive layer 1020 .

The first hole portion 101H1 is defined by the first sidewall SW1, the second hole portion 101H2 is defined by the second sidewall SW2, and the third hole portion 101H3 is defined by the third sidewall SW1. SW3) can be defined.

The sizes of the first hole portion 101H1 , the second hole portion 101H2 , and the third hole portion 101H3 may be different from each other. For example, the size of the first hole portion 101H1 is the smallest, the size of the second hole portion 101H2 is the largest, and the third hole portion 101H3 is the size and the second hole portion of the first hole portion 101H1. It may have a size between the size of the hole portion 101H2.

The first hole portion 101H1 may be formed by a laser cutting process. For example, a laser may be used to cut from the lower protective film 400 to the second adhesive layer 1020 . The second hole portion 101H2 may be a portion provided on the cushion member 500 , and the cushion member 500 may be punched to form the second hole portion 101H2 .

It may be attached to the lower protective film 400 . Accordingly, the sizes of the first hole portion 101H1 , the second hole portion 101H2 , and the third hole portion 101H3 may be formed to be different from each other in consideration of the component tolerance, the equipment tolerance, and the folding tolerance.

The folding tolerances may be tolerances generated by a folding operation of the electronic device 1000 . For example, it may be a tolerance in consideration of the amount of movement (or slip) of each component when the electronic device 1000 is fully folded, and a tolerance in consideration of the amount of unrestored movement of each component when unfolding after folding.

According to an embodiment of the present invention, since sizes of the first hole portion 101H1 , the second hole portion 101H2 , and the third hole portion 101H3 are determined in consideration of the folding tolerance, the first hole 101H ) and the electronic module inserted into the first hole 101H, for example, the camera module 2100 may not interfere with each other. In addition, the second light blocking pattern 362 disposed to correspond to the position of the first hole 101H may also be disposed in consideration of the folding tolerance. Accordingly, even when the electronic device 1000 is folded and unfolded, the second blocking pattern 362 may cover the active area 100A (refer to FIG. 4 ) of the display panel 100 or the angle of view area 2100AV of the camera module 2100 . ) can be reduced.

The camera module 2100 may be disposed to be inserted into the first hole 101H. A second upper adhesive layer 350 , a light blocking layer 360 , an impact absorbing layer 370 , and a second hard coating layer 380 may be disposed between the camera module 2100 and the window 340 . Accordingly, since at least one or more layers are disposed between the camera module 2100 and the window 340 , the possibility that the window 340 is damaged by the camera module 2100 may be reduced. Accordingly, product reliability can be improved.

The upper surface 2100U of the camera module 2100 may be located in the second hole portion 101H2 provided in the cushion member 500 . The second hole portion 101H2 may be a hole portion having the largest diameter among the first to third hole portions 101H1 , 101H2 , and 101H3 . Accordingly, even if the electronic device 1000 is folded and the positional relationship between the layers is changed, the probability of colliding with the second sidewall SW2 of the camera module 2100 may be reduced. Accordingly, product reliability can be improved.

The position of the upper surface 2100U of the camera module 2100 is not limited to the example illustrated in FIG. 6 . For example, the upper surface 2100U of the camera module 2100 may be disposed in the first hole portion 101H1 . In this case, the width 362W of the area surrounded by the second light blocking pattern 362 can be designed to be smaller than when the upper surface 2100U of the camera module 2100 is disposed on the second hole portion 101H2. have.

For example, the second blocking pattern 362 may be designed not to overlap the angle of view area 2100AV of the camera module 2100 . When viewed in a plan view, the second light blocking pattern 362 may be disposed to be spaced apart from the angle of view area 2100AV of the camera module 2100 by a predetermined distance in consideration of process errors. Since the camera module 2100 is closer to the second blocking pattern 362 , even if the width 362W of the area surrounded by the second blocking pattern 362 is reduced, the second blocking pattern 362 is the camera module. The angle of view region 2100AV of 2100 may not be blocked.

According to an embodiment of the present invention, the distance DT between the camera module 2100 and the window 340 may be secured to a predetermined distance or more. When the distance DT between the camera module 2100 and the window 340 is secured to be greater than or equal to a predetermined distance, the probability that the window 340 is damaged by the camera module 2100 may be reduced. Accordingly, product reliability can be improved. The damage may be a crack when the window 340 is a glass substrate, and may be a dent when the window 340 is a synthetic resin film.

For example, the distance DT may be 60% or more and less than 200% of the total sum of thicknesses of components having a modulus equal to or less than a reference modulus among components in which the first hole 101H is defined. Components in which the first hole 101H is defined in FIG. 3 may correspond to components disposed under the second hard coating layer 380 . The reference modulus may be 100 MPa or less, for example, 50 MPa or less and 0 MPa or more.

Each of the thicknesses may have a process error. Accordingly, the sum of the thicknesses may be 183 micrometers to 300 micrometers, for example, 235 micrometers. However, the sum of the thicknesses is not limited thereto.

The distance DT between the camera module 2100 and the window 340 may be determined in consideration of the maximum compression ratio of layers having a modulus less than or equal to the reference modulus. For example, the distance DT may be greater than or equal to a value obtained by multiplying the sum of the thicknesses by the maximum compression ratio. The distance DT may be 110 micrometers or more, for example, 141 micrometers or more.

According to an embodiment of the present invention, even if the components are maximally compressed by the pressure generated while using the electronic device 1000 , the window 340 and the camera module 2100 may be spaced apart from each other by a predetermined distance. Accordingly, the probability that the window 340 is damaged by the camera module 2100 may be greatly reduced. Accordingly, product reliability can be improved.
