PANEL AND DISPLAY DEVICE Russian patent published in 2023 - IPC G02F1/1362 H10K59/122 

FIELD: display technology.

SUBSTANCE: display panel contains a light-emitting structure layer (12), the light-emitting structure layer (12) contains a pixel definition layer (122). The pixel definition layer (122) contains a first dam section and a second dam section. The first dam section and the second dam section form a plurality of pixel holes, the distance between the surface of the side of the first dam section facing away from the base substrate (10) and the surface of the side of the planarization layer facing away from the base substrate (10) is less than the distance between the surface of the side of the second the dam portion facing away from the base substrate (10), and the surface of the side of the planarization layer facing away from the base substrate (10). The second dam portion includes a first surface of a side facing away from the base substrate (10) and a second surface of a side facing the base substrate (10), the first dam portion includes a third surface of a side facing away from the base substrate (10) and a fourth surface of a side facing the base substrate (10), and the distance between the first surface and the second surface is greater than the distance between the third surface and the fourth surface.

EFFECT: improved display quality.
