Abstract

A color light emitting display includes light-emitting devices of a plurality of red, green and blue pixels disposed in a matrix form. The light-emitting display takes out light from a side opposite to a substrate on which the light-emitting devices are formed. A wavelength of the light, of which an interference intensity to the light emitted from an emissive layer constituting a part of one of said light-emitting devices becomes a maximum value at 0 degree of a viewing angle, is λimax, a wavelength of the light becomes a minimum value in the interference intensity is λimin, a wavelength of the light becomes a maximum in a light intensity in relation to the light emitted from said emissive layer is λemax, and a relationship of λimax<λemax and λimin≧λemax+70 nm, is satisfied for at least one color among red, green and blue.

Claims (7)

1. A color light emitting display including light-emitting devices constituting a plurality of red, green and blue pixels disposed in a matrix form;

wherein said light-emitting display takes out light from a side opposite to a substrate on which said light-emitting devices are formed;

wherein a wavelength of the light, of which an interference intensity to the light emitted from an emissive layer constituting a part of one of said light-emitting devices becomes a maximum value at 0 degree of a viewing angle, is λimax;

wherein a wavelength of the light becomes a minimum value in the interference intensity is λimin;

wherein a wavelength of the light becomes a maximum in a light intensity in relation to the light emitted from said emissive layer is λemax; and

wherein a relationship of λimax<λemax, and λimin≧λemax+70 nm, is satisfied for at least one color among red, green and blue.

2. A color light emitting display according to claim 1 , wherein a change amount of a wavelength, the emission intensity of which becomes the maximum in relation to a light brought out to a viewer from said light-emitting display, makes change in a viewing angle from 0 to 60 degrees, the change amount becomes equal to or less than 10 nm.
