Abstract:
1. An organic light emitting diode display, comprising: a substrate; a thin film transistor on the substrate and including a gate electrode, a source electrode, and a drain electrode; a planarization layer formed on the thin film transistor and having a contact hole exposing a part of the drain electrode; a pixel electrode on the planarization layer and connected to the drain electrode of the thin film transistor through the contact hole; and a pixel defining layer on the planarization layer and having an opening exposing the pixel electrode, wherein the planarization layer has a single color throughout the display, and the pixel defining layer and the planarization layer have different colors and wherein a brightness of a mixed color of the pixel defining layer and the planarization layer is lower than a brightness of each color of the pixel defining layer and the planarization layer.
