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.

Abstract: A light emitting display device includes a substrate, an anode located on the substrate, a pixel defining layer located on the anode with a first opening defined therethrough to overlap the anode, a light emitting layer located within the first opening of the pixel defining layer, a cathode located on the light emitting layer and the pixel defining layer, an encapsulation layer located on the cathode, a scattering layer located on the encapsulation layer and including scattering particles, with a scattering layer opening defined therethrough to overlap the first opening in a plan view at least in part, and a light blocking layer located on the light blocking layer with a second opening defined therethrough to overlap the first opening in a plan view, where at least one selected from the first opening, the scattering layer opening, and the second opening has an oval shape.
