Abstract

A light emitting display device comprises a substrate, a first pixel electrode disposed on the substrate, a pixel defining film disposed on the first pixel electrode and having a first opening at least partially exposing the first pixel electrode, a first organic light emitting layer disposed on the pixel defining film and overlapping with the first opening of the pixel defining film, and a black matrix disposed on the first organic light emitting layer and having a first opening overlapping with the first organic light emitting layer. Light having passed through the first opening of the black matrix is one of red light, green light, and blue light. The first opening of the black matrix may have a shape with a curved portion.
