Abstract
An organic light emitting diode display includes: a substrate having first and second regions; a first thin film transistor (TFT) including source and drain electrodes at the first region; a second TFT including source and drain electrodes at the second region; a protective layer on the first and second TFTs; a planarization layer pattern on the protective layer; a first pixel electrode electrically connected to the source electrode or the drain electrode of the first TFT through a first via contact hole through the protective layer; and a second pixel electrode electrically connected to the source electrode or the drain electrode of the second TFT through a second via contact hole formed through the protective layer and the planarization layer pattern, the planarization layer pattern corresponding to a shape of the second pixel electrode and located between the protective layer and the second pixel electrode.
