Abstract:
An organic EL display panel in which pixels are arranged in a matrix, including: light-emitting layers disposed above pixel electrode layers in intervals between adjacent ones of column banks; an opposing electrode layer disposed above the light-emitting layers, the opposing electrode layer including a light-transmissive material; column light-shielding layers disposed higher than the pixel electrode layers, extending in the column direction, arranged side-by-side in the row direction, and overlapping row-direction edge portions of the pixel electrode layers in plan view of a substrate; and row light-shielding layers disposed higher than the pixel electrode layers, extending in the row direction, arranged side-by-side in the column direction, overlapping column-direction edge portions of the pixel electrode layers and partially overlapping contact regions in plan view of the substrate.
