Abstract
A light emitting display apparatus that achieves color display by using white light as a light source includes a plurality of organic light emitting devices each of which includes an organic light emitting layer that emits the white light. The organic light emitting device is configured so that a resonant wavelength in a thickness direction of the organic light emitting layer is positioned in the blue region of the spectrum. The light emitting display apparatus further includes a plurality of wavelength selection units each of which is provided on a path of the emission of the white light. The wavelength selection unit transmits light of a particular wavelength included in the white light.
