ABSTRACT:
Provided is a display apparatus, in which: among a red light emitting device, a green light emitting device, and a blue light emitting device, one or two of the organic light emitting devices include a metal translucent layer on a side closer to a second electrode with respect to a emission layer and a second reflection surface includes a surface of the metal translucent layer on a side of the emission layer; and the rest of the organic light emitting devices include a low-refractive index layer having a lower refractive index than the second electrode on the side closer to the second electrode with respect to the emission layer and the second reflection surface includes a surface of the low-refractive index layer on the side of the emission layer.
