Organic light emitting diode display having improved visibility

An organic light emitting diode (OILED) display comprising a plurality of pixels, each of the plurality of pixels comprising:

• a thin film transistor (TFT) comprising a gate electrode, a source electrode, and a drain electrode;
• a planarization layer on the TFT and including a contact hole at least partially exposing the drain electrode;
• a pixel electrode on the planarization layer and coupled to the drain electrode of the TFT through the contact hole;
• a pixel defining layer on the planarization layer and having an opening that exposes the pixel electrode;
• an organic emission layer on the pixel electrode;
• and
• a common electrode on the organic emission layer and the pixel defining layer,
• wherein the pixel defining layer comprises a corner-cube pattern comprising a plurality of corner cubes, each of the corner cubes comprising three planar surfaces meeting at a corner or point, such that each of the three planar surfaces of at least one of the corner cubes of the corner-cube pattern is configured to face the common electrode.
