1. An organic light emitting unit comprising three organic light emitting devices provided on a substrate, wherein the three organic light emitting devices have a structure in which a first electrode layer, a layer including a light emitting layer, and a second electrode layer are layered from the substrate side, and convert light generated in the light emitting layer to light of three colors different from each other and emit the converted light,wherein the first electrode layer has a structure in which a contact layer for improving contact characteristics with the substrate, a resonant layer for resonating light generated in the light emitting layer between the resonant layer and the second electrode layer, and a barrier layer for protecting the resonant layer are layered from the substrate side, andthe thickness of the barrier layer is different from each other among the three organic light emitting devices, and among the three organic light emitting devices each barrier layer includes a number of sub-barrier layers, the number of sub-barrier layers being different for each of the respective barrier layers.
