Abstract
Abstract An organic light-emitting device is formed of a transparent substrate, anodes in a stripe pattern formed on the transparent substrate, an organic film layer formed on the anodes, and cathodes formed on the organic film layer. Each of the anode includes a first conductor formed of a transparent and electrically conductive film containing a metal oxide as a main component, and a second conductor extending along the first conductor. The second conductor is formed of metal with a resistivity of +E,fra 1/10+EE or less than a resistivity of a constituent material of the first conductor. Thus, the organic light-emitting device emits light efficiently with a low power consumption.
