An organic EL display apparatus includes a plurality of pixels and a lens array which includes a light-condensing lens portion and a flat portion disposed on the light-emitting surface side of each pixel. Each pixel includes a light-emitting layer contained between a pair of electrodes. Part of the light emitted from the light-emitting layer is condensed by the light-condensing lens portion. A top surface of the light-condensing lens portion overlies the light-emitting region, and a part of the light-condensing lens portion is located outside the light-emitting region.
