In an organic EL display panel: banks that each extend in the column direction are disposed above a substrate; and red organic light-emitting layers, green organic light-emitting layers, and blue organic light-emitting layers each extend in the column direction and are disposed above the substrate in intervals between adjacent ones of the banks, wherein the banks define edges of sub-pixels of each color in the row direction, and in plan view of the substrate, surface areas of blue sub-pixels are greater than surface areas of red sub-pixels and greater than surface areas of green sub-pixels.
