Abstract

The present application provides a display panel and a display device. The display panel includes: a cathode inhibition layer disposed on a side of the pixel definition layer and between light-emitting units, a cathode disposed on a side of a light-emitting layer away from a substrate, and a color filter layer disposed on the cathode away from the substrate, wherein a thickness of the cathode on the cathode inhibition layer is less than a thickness of the cathode on the light-emitting unit. A light shielding portion of the color filter layer includes a light-permeable aperture configured corresponding to the cathode inhibition layer, and a light transmittance of a light-permeable material in the light-permeable aperture is greater than a light transmittance of the light shielding portion.
