Original Abstract Submitted
A light emitting display device includes: a substrate; anodes on the substrate; a pixel definition layer having first openings overlapping with the anodes, respectively; emission layers located within the first openings, respectively; a cathode on the emission layers and the pixel definition layer; an encapsulation layer on the cathode; and a light blocking layer on the encapsulation layer, and having second openings corresponding to the first openings, respectively. Each of the first openings has a circular shape in a plan view, and each of the second openings has an elliptical shape in a plan view. In a plan view, a first opening from among the first openings is in contact with a second opening corresponding to the first opening from among the second openings, or positioned within the second opening.
