Abstract

A color light emitting display includes light-emitting devices constituting a plurality of red, green and blue pixels disposed in a matrix form on a substrate, said light-emitting display takes out light from a side of said light-emitting devices opposite to said substrate on which said light-emitting devices are formed, and wherein when a wavelength of the light having an interference intensity of which with respect to the light emitted from an emissive layer constituting said light-emitting device becomes a maximum value at 0 degree of a viewing angle is λimax, and a wavelength of the light becomes a maximum in a light intensity of the light emitted from said emissive layer is λemax, a relationship of λemax−50 nm≦λimax<λemax is satisfied.

Claims (5)

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

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

wherein when a wavelength of the light having an interference intensity of which with respect to the light emitted from an emissive layer constituting said light-emitting device becomes a maximum value at 0 degree of a viewing angle is λimax, and a wavelength of the light becomes a maximum in a light intensity of the light emitted from said emissive layer is λemax, a relationship of λemax−50 nm≦λimax<λemax is satisfied.

2. A color light emitting display according to claim 1 , wherein when the viewing angle is changed from 0 to 60 degrees, a change in an amount of a wavelength of the light brought out to a viewer from said light-emitting display has the emission intensity which becomes a maximum is no greater than 10 nm.

3. The light emitting display according to claim 1 , wherein when a thickness of an organic film constituting said organic light-emitting diode device is RT in a red pixel, GT in a green pixel, and BT in a blue pixel, a relationship of RT≧GT≧BT is satisfied.
