Abstract
An organic EL device capable of ensuring reliable and easy insulation between electrodes during patterning of the electrodes. The organic EL device includes an organic EL layer including a luminous layer and arranged between anodes and cathodes, as well as electrode separation sections arranged so as to separate the anodes from each other while insulating them from each other. The electrode separation sections each include a plurality of insulating ribs juxtaposed to each other at predetermined intervals and arranged on the anodes or in proximity to a periphery of the,anodes. This permits the interval between the ribs juxtaposed to each other to prevent the material for the second electrodes from advancing through the top surface of the ribs to the side surface thereof, to thereby ensure positive insulation between the second electrodes.
