Abstract
An organic electroluminescent display (EL) device includes a substrate, an organic light emitting portion formed such that a positive electrode formed in a predetermined pattern, an organic layer formed on the positive electrode, and a negative electrode having a predetermined pattern in a direction orthogonal with the positive electrode are sequentially stacked, an encapsulation cap which encapsulates the organic light emitting portion, first and second groups of electrodes which are drawn out from at least one edge of the encapsulation cap and connected to the positive and negative electrodes to drive the organic light emitting portion, and first and second dummy electrodes formed at one side of the substrate.
