Abstract
The present invention provides an organic EL element and a manufacturing method therefor, which can reduce the number of steps and the cost required for manufacturing the organic EL element, and which can improve the reliability of the organic EL element, by preventing a short circuit, the breaking of a cathode, and the like. The organic EL element includes a plurality of transparent electrodes arranged in parallel on a base plate, a plurality of cathodes disposed above organic layers so as to cross the transparent electrodes, organic layers including light emission layers and disposed between the transparent electrodes and the cathodes, and an insulating organic layer disposed in spaces between adjacent transparent electrodes. The manufacturing method includes the steps of forming the transparent electrode, the insulating organic layer, the organic layer, and the cathode, which are carried out in a vacuum state.
