ABSTRACT:
A light emitting display includes light-emitting devices in which unnecessary layers for the emission operation of the light-emitting device are removed in an emission region, and in a case where a wavelength of a light, of which an interference intensity to the light emitted from an emissive layer constituting the light-emitting device becomes a maximum value at 0 degree of a viewing angle, is λimax and a wavelength of the light becoming a maximum in a light intensity in relation to the light emitted from the emissive layer is λemax, a relationship of λimax<λemax is satisfied, obtaining a light emitting display with a little variation in color over a wide range of viewing angles.
