The side band fixture 250 faces the band fixing side 251 and includes a body fixing side 252 extending in parallel with the up and down direction (y-axis direction) of the main body 20 to be fixed to the main body 20. .

The main body fixing side 252 is always fixed to maintain a posture extended in parallel with the up and down direction (y axis direction) of the main body 20, and is rotatable about the main body 20 about its longitudinal axis (y axis). Is formed. Accordingly, the side band fasteners can be rotated to both sides of the main body 20, and the end portions of the lateral head band 510 connected to the side band fasteners can be easily opened to both sides of the main body 20.

According to this configuration, the user can easily wear the display device 1 by opening the lateral head band 510 to both sides, and when adjusting the length of the lateral head band 510 after wearing, the lateral head The band 510 can easily stick to the head.

In addition, since the body fixing side 252 and the band fixing side 251 extend at a predetermined angle, when the user shortens the length of the lateral head band 510 for close contact, the body fixing side 252 A torque corresponding to the counterclockwise direction is formed in FIG. 3 around the upper end. In general, the forehead of the person protrudes more forward than the clown, so that the adhesion to the face of the bottom of the main body 20 is inferior to the top. Therefore, according to the above configuration, while the lower end of the main body 20 having a relatively weak ground can be lifted up, the main body 20 can be in close contact with the face of the user.

According to the present embodiment, the display device 2 is described as an apparatus for viewing a two-dimensional image as a three-dimensional stereoscopic image, but is not necessarily limited thereto. That is, the display device may be a device for enlarging a screen area for converting an image of the portable terminal 1 into a large high resolution image by using a convex lens.

In addition, the display device may be a virtual reality display device that provides a virtual reality (VR).

In addition, the portable terminal 1 is not limited to a device capable of wireless communication, such as a smart phone, it should be understood that if the portable small image equipment that can display an image on the screen may correspond to the portable terminal of the present invention. will be.

The display device of the present invention is not limited to a portable terminal such as a smart phone, and can be variously applied, such as being compatible with an image display device such as a tablet.
