Patent ID: 7531856

Claim:
A display apparatus comprising: a plurality of light-emitting devices disposed over a substrate having, in this or inverse order, a light transmissive electrode layer, a functional region including a light-emitting layer, and an opposing electrode layer; and a color conversion layer that is provided at a side of the light transmissive electrode layer for at least some of the light-emitting devices, wherein the light-emitting devices each have a reflective surface at a position opposite the light transmissive electrode layer with the functional region therebetween, and wherein an optical distance between the reflective surface and the light-emitting layer varies among the light-emitting devices depending on whether the color conversion layer is located at the light emitting device; and further, wherein the optical distance for any of the light-emitting devices that is not provided with the color conversion layer is set to a value with which interference occurs to the emitted light generated by the light-emitting layer of the light-emitting device, and the optical distance for any of the light-emitting devices provided with the color conversion layer is set to a value with which a light of a predetermined wavelength as a result of conversion by the color conversion layer is extracted with the highest level of intensity.
