Patent ID: 8664848

Claim:
An organic light emitting display device, comprising: a substrate; a plurality of thin film transistors (TFTs) formed on a first surface of the substrate; a passivation layer covering the plurality of TFTs; a plurality of first pixel electrodes formed on the passivation layer and respectively electrically connected to the plurality of TFTs, said first pixel electrodes overlapping with the plurality of TFTs so as to cover the plurality of TFTs, said first pixel electrodes including a reflection layer formed of a light-reflecting conductive material; a second pixel electrode formed of a light-transmissible conductive material and disposed on the passivation layer so as to be respectively electrically connected to the plurality of first pixel electrodes, a substantial portion of the first pixel electrodes not overlapping with the second pixel electrode, a substantial portion of the second pixel electrode not overlapping with the first pixel electrodes; an opposite electrode formed so that light is transmitted and reflected therethrough, said opposite electrode being disposed opposite to the plurality of first pixel electrodes and the second pixel electrode; and an organic layer interposed between the plurality of first and second pixel electrodes and the opposite electrode, and including an emission layer.
