  • Publication number: 20130187163
    Abstract: An organic light emitting diode (OLED) display with an improved light efficiency and a method of manufacturing the OLED display are disclosed. The OLED display includes a substrate, an insulation layer on the substrate and having concave portions, first electrodes on the insulation layer, pixel defining layers (PDLs) on the insulation layer and configured to define the first electrodes into pixels, organic light emitting layers on the first electrodes as defined by the pixels, and a second electrode on the organic light emitting layers. Each of the concave portions includes a bottom surface and inclined parts. Each of the first electrodes is on the bottom surface and the inclined parts of one of the concave portions. Embossings are on a part of a surface of the PDLs.
