Patent ID: 7750563

Claim:
A multicolor display apparatus comprising: a plurality of organic light-emitting devices of different emission colors each comprising a cathode, an anode, and an organic compound layer formed between the cathode and the anode, the organic compound layer comprising a light-emitting layer, wherein an optical path between a reflective surface which is closer to the cathode than the light-emitting layer is and a reflective surface which is closer to the anode than the light-emitting layer is, is set to serve as a resonating portion of a resonator structure for resonating light emitted by the light-emitting layer; wherein in the organic light-emitting device showing the emission color with a highest visual sensitivity of the plurality of emission colors, a wavelength at which light is most intensified by the resonance is longer than a peak wavelength of an emission spectrum of the light-emitting layer such that a color shift depending on a viewing angle of a white color displayed by mixing the plurality of emission colors is suppressed; and wherein in the organic light-emitting device showing an emission color other than the emission color with the highest visual sensitivity, a wavelength at which light is most intensified by the resonance coincides with a peak wavelength of the emission spectrum of the light-emitting layer.
