Abstract
Disclosed is an organic EL display panel provided with a substrate and a plurality of sub-pixels that are disposed in a matrix upon the substrate, wherein: the sub-pixels comprise sub-pixels that emit red light, sub-pixels that emit green light, and sub-pixels that emit blue light; the sub-pixels are each provided with a pixel electrode that is disposed upon the substrate, an organic functional layer that is formed by coating upon the pixel electrode, a counter electrode that is disposed upon the organic functional layer, and a bank that defines the space in which the organic functional layer is formed; the sub-pixels include sub-pixels (X) that are disposed on at least one section of the edge of the substrate, and sub-pixels (Y) that are disposed in the center of the substrate and that emit light with the same color as the sub-pixels (X); the volume of the organic functional layer provided in the sub-pixels (X) is larger than the volume of the organic functional layer provided in the sub-pixels (Y); and the sizes of the space defined by the bank provided in the sub-pixels (X) are the same as the sizes of the space defined by the bank provided in the sub-pixels (Y).
