摘要： 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.

摘要： The present invention overcomes image defects such as the brightness inclination or smears by reducing the line resistance of a power source bus line which supplies electricity to organic EL elements. A plurality of pixels which are arranged in a matrix array is connected to power source lines, and the plurality of power source lines are connected to a power source bus line. Both ends of the power source bus line are connected to a power source part via a FPC. By supplying electricity to both ends of the power source bus line from the power source part, the line resistance of the power source bus line can be reduced.
