In a multicolor display apparatus in which each of light emitting devices of three colors R, G and B has the same thickness from a reflection position of a reflection electrode to an organic emission layer, an organic emission layer of the R device and an organic emission layer of the B device each have electron transport property whereas an organic emission layer of the G device has hole transport property; and an optical distance (L) from the reflection position of the reflection electrode to an emission position of the organic emission layer in the light emitting devices of three colors satisfies 0.25×λR<L<0.75×λB, where λR and λB are peak wavelengths of emission spectra of the red light emitting device and the blue light emitting device. |
