Abstract
An organic light emitting display device comprises: 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, and overlapping with the plurality of TFTs so as to cover the plurality of TFTs, and including a reflection layer formed of a light-reflecting conductive material; a second pixel electrode formed of a light-transmitting conductive material and disposed on the passivation layer so as to be electrically connected to the plurality of first pixel electrodes; an opposite electrode formed such that light is transmitted or reflected therethrough, and disposed opposite the plurality of first pixel electrodes and the second pixel electrode; and an organic layer interposed between the plurality of first pixel electrodes and the second pixel electrode, and including an emission layer. Accordingly, transmittivity of the organic light emitting display device is increased, and optical outcoupling efficiency of the organic light emitting display device is also i…
