Abstract

A light emitting display apparatus is disclosed, which can improve visual characteristic of a black image in accordance with reduction of diffuse reflectance while improving light emission efficiency of light emitted from a light emitting diode. The light emitting display apparatus comprises a substrate including a plurality of pixel areas, a light emission pattern arranged in each of the plurality of pixel areas, a light emitting device layer arranged over the light emission pattern, and a selective wavelength absorbing member overlapped with at least one of the plurality of pixel areas, wherein the selective wavelength absorbing member may reduce transmittance of light of a long wavelength, which is incident.
