Abstract:
Disclosed in the present application are an OLED display panel and a display device. In the OLED display panel of the present application, a photoresist structure of a color film layer uses the mode of stacking two defining layers, a slope surface is formed between corresponding color resist defining areas on the two defining layers, and the color resist units of the color film layer are formed in the corresponding color resist defining areas and correspond to the light-emitting units of an organic light-emitting layer. The present application reduces the use amount of materials of the color film layer, and uses a solvent-free material for printing, thereby avoiding the influence of the volatilization of a solvent on environment.
