The display panel has a plurality of corners 50, the corners 50 are arc-shaped corners, a plurality of grooves 1 are disposed at each corner 50, and the grooves 1 are distributed at the corners 50 in a fan shape (see fig. 1). The groove 1 extends from the edge of the non-display area 20 of the display panel to the bending area 30, that is, the groove 1 is formed by slotting from the edge of the non-display area 20 to the bending area 30.

The inner diameter of the groove 1 is largest at the edge of the non-display area 20, and the farther from the edge of the non-display area 20, the smaller the inner diameter of the groove 1 (see fig. 2), facilitating bending.

The grooves 2 are disposed on a side of the groove 1 away from the edge of the non-display area 20, that is, on an outer side of the groove 1, and in the bending area 30, the display panel includes a plurality of grooves 2, and each of the grooves 2 is arranged in parallel (see fig. 2).

As shown in fig. 3 and 4, the longitudinal section of the excavation 2 is "U" shaped, the excavation 2 is recessed in the cushioning layer 200 and the base layer 100, and extends from the cushioning layer 200 to the second flexible base layer 130, specifically, the excavation 2 includes a first groove body 21 and a second groove body 22 which are communicated with each other. The first channel 21 extends from the buffer layer 200 to the second flexible base layer 130, and is recessed in the buffer layer 200 and a portion of the second flexible base layer 130, and a first notch 211 is formed at the buffer layer 200. The second slot 22 extends from the first slot 21 into the second flexible base layer 130, is recessed from a portion of the second flexible base layer 130, and forms a second notch 221 and a slot bottom 222 in the second flexible base layer 130, wherein the area of the first notch 211 is smaller than the area of the slot bottom 222, and the area of the first notch 211 is equal to the area of the second notch 221.

In this embodiment, the grooves 2 are four, each of the grooves 2 includes at least one first groove 210 and at least one second groove 220, each of the second grooves 220 is close to the display area 10, and each of the first grooves 210 is far away from the display area 10, wherein the groove width of each of the first grooves 210 is smaller than that of each of the second grooves 220, and the purpose of each of the grooves 2 is to share stress applied to the display panel during bending, thereby preventing the film layer from breaking and improving the bending performance of the display panel.

The array layer 300 is disposed on the upper surface of the buffer layer 200 and extends from the display region 10 to the GOA region 40, and is used as a circuit control switch of the display panel.

The thickness of organic layer 400 is less than the thickness of encapsulation layer 500, because the thickness of organic layer 400 is very little, so it can break off at the kneck of first cell body 21 and second cell body 22, because the thickness of encapsulation layer 500 is great, so it can not break off at the kneck of first cell body 21 and second cell body 22, can extend to the tank bottom 222 of second cell body 22, encapsulate 2 full package digging groove, because organic layer 400 conducts steam easily, after the disconnection of organic layer 400, can effectively prevent steam from getting into the inside of digging groove 2, improve display device's encapsulation effect. The requirement on the precision of the mask is very high when the organic layer 400 is manufactured to be completely consistent with the edge of the non-display area 20, and the organic layer 400 consistent with the edge of the non-display area 20 in shape can be manufactured without the high-precision mask in the embodiment.

The technical effect of the display device is that the grooves are arranged in the grooves in parallel, the organic layer is broken at the grooves, water vapor is effectively prevented from entering the grooves, the packaging effect of the packaging layer is improved, and the yield of the display device is further improved.
