Abstract
A display panel and a display device are provided, featuring a first substrate with a first base and a pixel electrode layer on one side. A light-modulating medium layer is on one side of the pixel electrode layer, facing away from the first base. The second substrate, on one side of the light-modulating medium layer away from the first substrate, includes a second base and a common electrode layer facing the light-modulating medium layer. The first substrate includes a first organic insulating layer between the first base and the pixel electrode layer, causing a surface of the pixel electrode layer facing away from the first base to be uneven. Alternatively, the second substrate includes a second organic insulating layer between the second base and the common electrode layer, making the common electrode surface uneven. This design enhances display effects at wide angles while ensuring high aperture ratio and light transmittance.
