Summary:A light emitting display device includes a substrate, a plurality of anodes (Anode) on the substrate, a pixel defining layer having a plurality of first openings (OP, OPr, OPg, OPb) overlapping the anodes (Anode), a plurality of emission layers (EML) in the first openings (OP, OPr, OPg, OPb) of the pixel defining layer, a cathode (Cathode) formed on the emission layers (EML) and the pixel defining layer, an encapsulation layer on the cathode (Cathode), and a light blocking layer on the encapsulation layer and having a plurality of second openings (OPBM, OPBMr, OPBMg, OPBMb) corresponding to the first openings (OP, OPr, OPg, OPb), wherein the first openings (OP, OPr, OPg, OPb) and the second openings (OPBM, OPBMr, OPBMg, OPBMb) respectively have an oval shape in a plan view, and wherein long-axis angles of the second openings (OPBM, OPBMr, OPBMg, OPBMb) include at least five different angles.
