Abstract:
1. A display device comprising a plurality of pixels and which realizes a color display using emitted light of at least two wavelengths, wherein each of the plurality of pixels comprises 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, the organic light emitting element layer having at least one layer, a conductive resonator spacer layer having an individual pattern for each pixel is provided between the lower reflective film and the organic light emitting element layer, at least the conductive resonator spacer layer provided in a part of the plurality of pixels comprises a plurality of transparent conductive metal oxide layers and a light transmissive layer provided between the transparent conductive metal oxide layers and having an index of refraction with a difference within 25% from an index of refraction of the transparent conductive metal oxide layer, and light obtained in the organic light emitting element layer is intensified by the niicroresonator structure formed between the lower reflective film and the upper reflective film and is emitted to the outside.
