Abstract
The present disclosure relates to a display panel and a display device. The display panel includes a substrate, a light-emitting layer, an encapsulation layer, and a light-filtering layer. The light-filtering layer is used to filter and adjust light emitted by the light-emitting layer to improve luminous purity of a red light-emitting unit and a green light-emitting unit, thereby adjusting the light emitted by the light-emitting layer of the display panel to R (0.708, 0.292), G (0.170, 0.797), and B (0.131, 0.046), thereby effectively achieving high BT2020 color gamut coverage and improving the color display capability of the display panel.
