Abstract:
1. An organic light emitting diode (OLED) display comprising: a substrate member including a plurality of pixel areas; a thin film transistor (TFT) including a gate electrode, a source electrode, and a drain electrode and formed on the substrate member; a planarization layer formed on the TFT and having a contact hole through which the drain electrode is partially exposed; a pixel electrode formed on the planarization layer, and connected to the drain electrode of the TFT through the contact hole; an organic emission layer formed on the pixel electrode; a common power line formed over the substrate member and at least partially covered by the planarization layer; a common electrode formed on the organic emission layer and comprising a plurality of curved portions at least two of which are formed substantially directly above the common power line; a pixel defining layer formed on the planarization layer and having a through opening; and a light scattering spacer formed on the pixel defining layer, wherein the light scattering spacer comprises a plurality of sub-spacers formed in each of the pixel areas and extending from the pixel defining layer, and wherein the sub-spacers are adjacent to and separated from each other by the curved portions of the common electrode.
