Patent ID: 7510455

Claim:
A method for manufacturing a display device comprising a plurality of pixels, and in which each pixel comprises a microresonator formed between a lower reflective film 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, an optical length corresponding to a distance between the lower reflective film and the upper reflective film of the microresonator differing among pixels corresponding to light emission wavelengths, and a color display being realized by emitted light of at least two wavelengths, wherein a conductive resonator spacer layer having a single layer or a multilayer structure of a transparent conductive metal oxide is formed in each pixel after the lower reflective film is formed and before the organic light emitting element layer is formed, and a number of layers, or a number of layers which are not removed and are left after the transparent conductive metal oxide layers are layered, of the transparent conductive metal oxide layers is changed among pixels having different light emission wavelengths so that a total thickness of the conductive resonator spacer layer for adjusting the optical lengths is changed.
