Abstract
An organic EL device includes a substrate; a color filter layer that is formed above the substrate; a first electrode that is formed between the substrate and the color filter layer; a second electrode that is formed to face the first electrode; and an organic light-emitting layer that is formed between the first and second electrodes. The color filter layer includes first and second sub-filter layers that are formed in a region overlapping the first electrode, when viewed from a direction perpendicular to the substrate, and transmit a first color. The first and second sub-filter layers are formed of the same material and the first and second sub-filter layers are laminated.
