Abstract
A display device includes a plurality of pixels and realizes a color display using emitted light of at least two wavelengths. Each pixel has a microresonator structure formed between a lower reflective film formed on a side near a substrate and an upper reflective film formed above the lower reflective film with an organic light emitting element layer therebetween. A conductive resonator spacer layer is provided between the lower reflective film and the organic light emitting element layer. Light obtained in the organic light emitting element layer is intensified by the microresonator structure in which the optical length is adjusted by the conductive resonator spacer layer and is emitted to the outside.
