Abstract

An organic light-emitting display panel is provided. The organic light-emitting display panel includes a substrate and a plurality of pixel units disposed on a side of the substrate, wherein the pixel unit includes an organic light-emitting diode (OLED); the substrate has a first pixel density area and a second pixel density area, and a density of pixel units in the first pixel density area is greater than that of pixel units in the second pixel density area; and in the second pixel density area, a light-emitting surface of the OLED protrudes along a light-emitting direction of the OLED.
