Abstract

An electroluminescent display panel includes a plurality of repeating units each including a first conductive layer, a first insulating layer including a first via hole, and an anode including a main body and an auxiliary portion. At least one repeating unit includes a first-color sub-pixel, a second-color sub-pixel, and a third-color sub-pixel; the area of the main body of the third-color sub-pixel is larger than that of the second-color sub-pixel and that of the first-color sub-pixel; and an overlapping area between the main body of the third-color sub-pixel and the first conductive layer is larger than that between the main body of the second-color sub-pixel and the first conductive layer, and the overlapping area between the main body of the third-color sub-pixel and the first conductive layer is larger than that between the main body of the first-color sub-pixel and the first conductive layer.
