Abstract: An organic electroluminescence (EL) display panel includes pixels arranged in a matrix of rows and columns, and includes: a substrate; pixel electrode layers that are arranged on the substrate in the matrix; an insulating layer that is provided above the substrate and the pixel electrode layers, and has elongated openings and a grooved portion for each of the pixels, the openings extending in a column direction and being arranged in a row direction, the grooved portion having an upper opening and a bottom and being communicated with at least one of the openings in plan view; organic functional layers that are provided above the pixel electrode layers, and include light emitting layers in which organic electroluminescence occurs in the openings; and a light-transmissive counter electrode layer that is provided above the organic functional layers. Cross-sectional profiles of the openings taken along the row direction are uniform in the column direction.
