Display panel and display device

The utility model provides a display panel and a display device. The display panel comprises a substrate and a plurality of light-emitting units. The dielectric layer is arranged on the side, away from the substrate, of the light-emitting unit, the dielectric layer comprises a first surface close to the light-emitting unit and a second surface away from the light-emitting unit, the first surface is parallel to the plane where the substrate is located, and the second surface is parallel to the plane where the substrate is located. In the direction from the center of the display area to the edge of the display area, the end, close to the center of the display area, of the second surface inclines towards the side away from the light-emitting unit, or the end, away from the center of the display area, of the second surface inclines towards the side away from the light-emitting unit; a lens and a filling layer. Therefore, the angle customization function of the display panel can be improved, and meanwhile, the brightness loss of a specific angle is reduced.
