Abstract
An organic light emitting diode (OLED) display panel includes a substrate, a reflective electrode disposed on the substrate, and a pixel define layer (PDL) formed on the substrate and the reflective electrode layer. The reflective electrode layer has multiple reflective structures, and each reflective structure has a first region and a second region. The PDL is provided with multiple openings corresponding to the reflective structures, such that the first region and the second region of each of the reflective structures are exposed in a corresponding one of the openings. Multiple organic emissive structures are correspondingly formed in the openings and covering the reflective structures, forming a plurality of pixels. For each respective pixel of the pixels, a first reflective ratio of the respective pixel corresponding to the first region is greater than a second reflective ratio of the respective pixel corresponding to the second region.
