An organic light emitting display (OLED) device includes a substrate, a plurality of first electrodes, a plurality of light emitting layers, a second electrode, a power supply line, a third electrode, and an encapsulation member. The third electrode that is formed on the power supply line and the second electrode that is formed on the light emitting layers extend to a contact region that is in a peripheral region of the substrate. The third electrode and the second electrodes have an uneven pattern in the contact region.
