In this embodiment, the dam 5 has a rectangular ring shape, and matches the shape of the display area 204. Wherein the width w of the dam 5 is 2 μm. I.e. the process is repeated. The dam 5 occupies a small space in the non-display region 205, which is beneficial to the narrow bezel design of the flexible display panel 21. It should be noted that the number of the dams 5 is not limited to the one shown in fig. 4.

In other embodiments, the first groove 501 may also have a cylindrical shape, an inverted cone shape, or other shapes, which is not specifically limited in this application. It should be noted that the dam 5 in this embodiment extends along the edge of the display area 204. In other words, the extending direction of the dam 5 is the circumferential direction of the display area 204. Wherein a part of the dam 5 extends in the lateral direction of the display area 204 and a part of the dam 5 extends in the longitudinal direction of the display area 204 as shown in fig. 6.

In this embodiment, the plurality of second grooves 502 and the plurality of first grooves 501 are disposed in a staggered manner in a direction perpendicular to the extending direction of the dam 5 (the Y-axis direction shown in fig. 6). It should be noted that the second groove 502 and the first groove 501 are arranged in a staggered manner, which means that the second groove 502 isCenter O2Located at the center O of two first grooves 501 adjacent thereto1In the meantime. I.e. the center O of the second groove 5022The projection on the central connecting line of two adjacent first grooves 501 is positioned at the center O of the first groove 5011In the meantime.
Because a plurality of second recess 502 and a plurality of first recess 501 dislocation set, the geometric centre line of dam 5 and the extending direction nonparallel of dam 5, at the folding in-process of flexible display panel 21, can reduce the stress accumulation of dam 5 itself, prevent stress along the extending direction accumulation of dam 5, guarantee the structural strength of dam 5, avoid flexible display panel 21's layer structure to take place the fault bed, lead to the unable matching of cathode layer 43 and luminescent layer 42 and show the problem of inefficacy.
It should be noted that, in other embodiments, the surface of the dam 5 facing away from the substrate 1 may also be partially recessed to form other grooves besides the first groove and the second groove, as long as the geometric centerline of the dam 5 is ensured not to be parallel to the extending direction of the dam 4, which is not specifically limited in this application.

Further, the width D of the first groove 501 is smaller than or equal to the width D of the groove sidewall 303 of the pixel groove 301 in the direction parallel to the substrate 1. In this example, D is not more than 2.5 μm. Because the width D of the first groove 501 is less than or equal to the width D of the groove sidewall 303 of the pixel groove 301, when the flexible display panel 21 is folded, the cathode layer 43 and the encapsulation layer 7 cannot slide along the groove sidewall 303 of the pixel groove 301, so that the cathode layer 43 and the organic material layer 3 cannot slide relatively, the problem that the cathode layer 43 and the light-emitting layer 42 cannot be matched due to layer staggering is avoided, and normal display of the flexible display panel 21 is ensured.
