The present disclosure provides a display panel and display device. The display panel comprises a drive substrate, a light-emitting device layer, an encapsulation layer, and an optical film layer. The light-emitting device layer is located on the drive substrate. The encapsulation layer covers the light-emitting device layer. The optical film layer is located on the encapsulation layer, and multiple openings are provided on the optical film layer. The color filter layer includes multiple color resistors, which are arranged within the opening. The refractive index of the optical film layer gradually decreases along a direction away from the encapsulation layer through the optical film layer.
