Wherein, in fig. 2, fig. 4, fig. 6, and fig. 8, the front view pattern of the first surface 301 is a first pattern in the front view direction of the first side 101; the front pattern of the second surface 302 in the front direction of the second side 102 is shown in fig. 2, 4, 6, and 8.
When the folded display panel 100 is in a flattened state, the first surface 301 of the cover layer 300 is seen from the first side 101, in the front view direction of the first side 101, the first pattern is a bottom view pattern of the first surface 301, the second surface 302 of the cover layer 300 is seen from the second side 102, in the front view direction of the second side 102, the bottom view pattern of the second surface 302 is a second pattern, and the first pattern is different from the second pattern, so that the first surface 301 and the second surface 302 are easily distinguished when the cover layer 300 is attached, and the front and back surfaces of the cover layer 300 are easily distinguished, thereby avoiding the influence on the bending performance of the cover layer 300 due to the front and back attachment, and ensuring the product quality of the folded display panel 100. Taking the folded display panel 100 as an example, the first surface 301 is on the outer side of the fold, and the second surface 302 is on the inner side of the fold.
In some embodiments, the cover layer 300 includes at least one first opening 310, and one edge of the first opening 310 is flush with one edge of the cover layer 300 or both edges of the first opening 310 are flush with both edges of the cover layer 300 in the front view of the first side 101 or the second side 102.
The first opening 310 may be formed at an edge of the cover layer 300, and may be conveniently opened, i.e., may be provided at any one of the upper, lower, left and right edges, or may be provided at an angular edge, in a front view direction of the first side 101 or the second side 102, i.e., in a bottom view or a top view direction of the folded display panel 100, as a mark for distinguishing the front and back sides of the cover layer 300.

In some embodiments, the curvature of the upper and lower arc angles of the folded display panel 100 is different, and the curvature of the upper and lower arc angles of the cover sheet layer 300 is different. By the different curvatures of the upper and lower arc angles, the upper and lower positions of the cover plate layer 300 can be distinguished, and the cover plate layer 300 is prevented from being turned upside down, so that the bending performance of the cover plate layer 300 is prevented from being adversely affected due to the turning upside down, and the product quality of the folded display panel 100 is ensured.
