Abstract: A light emitting display device includes a substrate, anodes disposed on the substrate, a pixel defining layer having first openings overlapping each of the anodes, light emitting layers each disposed within the first openings of the pixel defining layer, a cathode disposed on the light emitting layers and the pixel defining layer, an encapsulation layer disposed on the cathode, and a light blocking layer disposed on the encapsulation layer and including second openings each overlapping the first openings. One unit pixel includes two light emitting areas of a first color, one light emitting area of a second color, and one light emitting area of a third color. The light emitting areas of the first color have a diamond shape, the second color and the third color light emitting areas each have a rectangular shape, and at least one second opening has an oval shape.
