Abstract
An organic electroluminescence (EL) display panel having pixels arranged in a matrix of rows and columns includes: a substrate; pixel electrode layers that are made of a light-reflective material and are arranged on the substrate in the matrix; an insulating layer that is provided above the substrate and the pixel electrode layers; organic functional layers that are provided above the pixel electrode layers; and a light-transmissive counter electrode layer that is provided above the organic functional layers, wherein the insulating layer has a first opening and second openings for each of the pixel electrode layers, the first opening being elongated in a column direction, the second openings each being shorter than the first opening in the column direction and being lined up adjacent to the first opening, and the organic functional layers include light-emitting layers in which organic electroluminescence occurs in the first opening and the second openings.
