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： A plurality of organic EL elements which are arranged on a display panel lowers the brightness along with a lapse of light emitting time and hence, the power consumption is increased to maintain the brightness. However, the increase of the power consumption shortens a lifetime of the organic EL elements. To overcome this drawback, a power supply circuit which drives the display panel has a function of controlling an electric power supplied to the display panel to a fixed value or less in response to a detection signal from a detection part which detects a cathode current of the organic EL elements.
