Abstract
Embodiments of the present disclosure are directed to a display panel and a display device. The display panel includes a light-emitting functional layer disposed on a substrate, a dimming metal array layer disposed on a side of the light-emitting functional layer away from the substrate, and a circular polarizer. The circular polarizer includes a linear polarizing layer and a quarter-wave plate disposed on a side of the dimming metal array layer away from the light-emitting functional layer. The dimming metal array layer is configured to convert light into elliptically polarized light. A included angle between an elliptical long axis direction of the elliptically polarized light and a light transmission axis direction of the linear polarizing layer is less than or equal to 45 degrees.
