Organic electroluminescent device

Abstract

An organic electroluminescent display (EL) device which can prevent damage to layers due to a deposition mask in forming a light emitter layer or cathode using a deposition mask, and can prevent the short-circuit between a first electrode formed on a transparent substrate and a second electrode corresponding to the first electrode and can prevent deterioration of layer characteristics, and a method of manufacturing the same. The organic EL device includes a substrate made of a transparent material, a first electrode unit having a plurality of electrodes formed on the substrate in a predetermined pattern, a second electrode unit having a plurality of electrodes arranged in a direction crossing the first electrode unit, an electroluminescent layer disposed between the first electrode unit and the second electrode unit and configured to cover at least the first electrode unit and to emit light at the intersection of the first and second electrode units, inter-insulators positioned under the electroluminescent layer so as to cover at least spaces of each of the respective electrodes of the first electrode unit, and configured to define the first electrode unit as a plurality of light emitting areas and to prevent the short-circuit between the first electrode unit and the second electrode unit, and insulating walls positioned on at least one of the top and bottom surfaces of the inter-insulators.
