Abstract
An organic light emitting display device includes a substrate including a plurality of pixel regions and a plurality of transparent regions, thin film transistors disposed in the pixel regions, an insulation layer disposed on the thin film transistors, first electrodes electrically contacting the thin film transistors, a pixel defining layer including a black material disposed on the first electrodes, organic light emitting structures disposed on the pixel defining layer, and a second electrode disposed on the organic light emitting structures. The pixel defining layer may define an asymmetrical configuration of adjacent transparent regions disposed on opposing sides of corresponding pixel regions.
