ABSTRACT:
An organic light emitting diode display includes a substrate, a thin film transistor, a planarization layer, a pixel electrode, and a pixel defining layer. The thin film transistor is formed on the substrate and includes a gate electrode, a source electrode, and a drain electrode. The planarization layer is formed on the thin film transistor and has a contact hole that exposes a predetermined part of the drain electrode. The pixel electrode is formed on the planarization layer and is connected to a drain electrode of the thin film transistor through the contact hole. The pixel defining layer is formed on the planarization layer and has an opening that exposes the pixel electrode. The pixel defining layer and the planarization layer have different colors.
