An organic device comprising light emitting elements arranged on a substrate is provided. Each of the light emitting elements comprises, from a side of the substrate, a reflection layer, a light-shielding member, a first electrode, an organic layer including a light emitting layer, and a second electrode. The light emitting elements comprise a first element and a second element arranged adjacent to each other. A length in a second direction of a portion of the light-shielding member is longer than that of the portion in a first direction, the portion being arranged in a region where the first and second element are adjacent to each other, and the first direction is a direction in which the first and second element are arranged and the second direction is a direction perpendicular to the first direction.
