Display panel and display device

The invention provides a display panel and a display device. The display panel is provided with a plurality of light-emitting areas, and each light-emitting area comprises a main light-emitting area and a transparent area located on at least one side of the main light-emitting area. The display panel comprises a substrate, a light-emitting part, a polarizing film layer and an optical function layer. Wherein the light-emitting part is arranged on one side of the substrate, located in the main light-emitting area and used for emitting first polarized light with a first polarization direction and second polarized light with a second polarization direction. The polarizing film layer is located on the side, away from the substrate, of the layer where the light-emitting part is located and used for transmitting the first polarized light and reflecting the second polarized light. The optical function layer is located on the side, close to the substrate, of the polarization film layer. When the optical functional lay
