Abstract
Display panels and display devices are provided. The display panel includes a substrate, a plurality of pixel driving units and a plurality of photosensitive units disposed on the substrate, a first planarization layer disposed on a side of the pixel driving units and the photosensitive units away from the substrate, a second planarization layer disposed on a side of the first planarization layer away from the substrate, and a light-emitting element layer disposed on a side of the second planarization layer away from the substrate. The first planarization layer has a first refractive index, and the second planarization layer has a second refractive index less than the first refractive index. At least one of the first planarization layer and the second planarization layer includes a resistance material.
