Abstract
An organic light emitting display device may include a base substrate including an emission area at which light is emitted and a peripheral area which is adjacent to the emission area; an encapsulation substrate disposed on the base substrate; a common layer between the base substrate and the encapsulation substrate, the common layer disposed in both the emission area and the peripheral area; between the base substrate and the common layer, each of: a planarization layer; a pixel electrode in the emission area; and a pixel defining layer; and a discharging hole disposed corresponding to the pixel defining layer, the discharging hole extending through the common layer.
