The existing front camera usually has 3 corresponding punching modes: (1) the through hole screen and the through hole scheme of the LCD are that an LCD panel, a polarizing plate and backlight are punched together, so that the process from glass to a module becomes more complicated. (2) The blind hole screen with the liquid crystal does not need to drill a physical hole completely on the screen, only needs to drill holes on the backlight layer and the polarizer layer on the TFT LCD display screen, does not need to drill holes on the array glass and the color film glass substrate, but needs to perform mask separation at the hole part, does not manufacture a graph, and the liquid crystal of the hole part is also left in the panel. (3) The blind hole screen without liquid crystal is similar to the blind hole screen with liquid crystal in structure, and the blind hole screen without liquid crystal has the greatest difference that whether liquid crystal exists in a panel layer or not and liquid crystal in a hole area is removed, but an additional packaging process is needed for blocking the liquid crystal.

In some embodiments of the present disclosure, the distance between the strip-shaped spacer 1412 and the array substrate 101 is smaller than the distance between the column-shaped spacer 1411 and the array substrate 101, so that the strip-shaped spacer 1412 and the column-shaped spacer 1411 can provide multi-level support when being pressed around the blind hole, thereby ensuring the cell thickness and the uniformity of the liquid crystal layer arrangement as much as possible, avoiding the occurrence of yellowing, and improving the display quality of the display panel 100.
In some embodiments of the present application, the shortest distance between two adjacent strip-shaped spacers 1412 is smaller than the shortest distance between two adjacent column-shaped spacers 1411, so that the supporting density around the blind hole can be increased, and the problem of yellow boundary of the blind hole can be prevented.
In some embodiments of the present application, as shown in fig. 3, a light shielding layer 142 is disposed on the opposite substrate 102, and an orthogonal projection of the light shielding layer 142 on the opposite substrate 102 covers the transition region 130, so that light emitted from the backlight source can be shielded by the light shielding layer 142, thereby preventing a light leakage phenomenon from occurring in the transition region 130 between the display region 110 and the blind hole region 120 in the display panel 100.

In addition, while the height difference of at least part of the spacers 141 in the transition region 110 is realized, a new layer (the layer structure of the blind hole region 120 is the same as that of the display region 100) is not introduced, thereby simplifying the manufacturing process.
In some embodiments, the orthographic projection of the cushion layer 143 on the counter substrate 102 at least partially overlaps with the orthographic projection of the strip-shaped spacers 1412 on the counter substrate 102; further, an orthogonal projection of the bar-shaped spacer 1412 on the opposite substrate 102 is located within an orthogonal projection of the cushion layer 143 on the opposite substrate 102. Therefore, the strip-shaped spacers 1412 can be lifted, and the height difference between the columnar spacers 1411 and the strip-shaped spacers 1412 is increased, so that the columnar spacers 1411 start to provide support only when the strip-shaped spacers 1412 are deformed and cannot provide support under the action of enough external force around the blind holes, thereby improving the pressure resistance around the blind holes, effectively ensuring the uniformity of the box thickness and the liquid crystal layer arrangement, avoiding the yellowing phenomenon, and improving the display quality of the display panel 100.
