Abstract
The present disclosure provides an organic light-emitting diode (OLED) display panel and a display device. The OLED display panel includes a substrate, a light-emitting layer, a black matrix layer, a transparent planarization layer, and a color resist layer. The transparent planarization layer is disposed on the light-emitting layer and at least completely fills openings of the black matrix layer. The color resist layer is disposed on the transparent planarization layer. An orthographic projection of the color resist layer on the substrate partially overlaps an orthographic projection of the black matrix layer on the substrate, so as to prevent a bullhorn phenomenon due to a mutual covering film design between the color resist layer and the black matrix layer.
