Abstract:
An organic light emitting display provided according to the invention maintains light emission efficiency and elongates its lifetime by radiating heat generated from organic light emitting elements to the outside of an encapsulated area. In the organic light emitting display, a part of a cathode is extended to the outside of the encapsulated area of a main substrate to form a radiation section integrally with the cathode. Heat generated from organic light emitting elements is diffused and radiated from the radiation section so that the heat can be discharged therefrom.
