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.

An organic light-emitting diode (OLED) display panel, comprising:
- a substrate;
- a light-emitting layer disposed on the substrate and comprising a plurality of light-emitting pixels;
- a black matrix layer disposed on the light-emitting layer and defined with a plurality of openings corresponding to the light-emitting pixels;
- a transparent planarization layer disposed on the light-emitting layer and at least completely filling the openings, wherein a thickness of the transparent planarization layer ranges from 1 um to 5 um;
- and
- a color resist layer disposed on the transparent planarization layer corresponding to the light-emitting pixels, wherein an orthographic projection of the color resist layer on the substrate partially overlaps an orthographic projection of the black matrix layer on the substrate, and the color resist layer completely covers regions corresponding to the openings.
