An organic EL display device includes a substrate, a fin structure on the substrate, the fin structure standing upright in a thickness direction of the substrate, a first electrode formed on at least a part of a side surface of the fin structure, an organic film which is laminated so as to cover a surface of the first electrode on the side surface of the fin structure, a second electrode that is transparent and laminated so as to cover a surface of the organic film on the side surface and a top portion of the fin structure, a color filter layer that is formed on a path that light travels after being emitted from the light emitting layer and passing through the second electrode and formed at least above the organic film laminated on the side surface, and a light blocking layer configured to block light formed above the top portion of the fin structure.
