Abstract:
1. A display apparatus, comprising a plurality of organic light emitting devices including a red light emitting device, a green light emitting device, and a blue light emitting device, each of the organic light emitting devices having an organic layer including a emission layer formed between a first electrode and a second electrode from which light is extracted, the each of the plurality of organic light emitting devices having a cavity structure in which light emitted in the emission layer is resonated between a first reflection surface provided on a side closer to the first electrode with respect to the emission layer and a second reflection surface provided on a side closer to the second electrode with respect to the emission layer, wherein: one or two of the organic light emitting devices having three colors include a metal translucent layer on the side closer to the second electrode with respect to the emission layer, and the 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.
