Patent ID: 8415873

Claim:
An organic light emitting display device, comprising: a substrate having a transmitting region and a plurality of separate pixel regions that are interposed within the transmitting region and that are spaced apart from each other, the plurality of separate pixel regions including a plurality of pixel circuit units, respectively; thin film transistors that are positioned on a first surface of the substrate, the thin film transistors being on the separate pixel regions, respectively; a passivation film covering each of the thin film transistors and the transmission region; pixel electrodes that are reflection electrodes arranged on the passivation film, each of the pixel electrodes being electrically connected to one of the thin film transistors and being disposed to overlap and cover the one of the thin film transistors, and each of the pixel electrodes overlapping an entirety of one of the pixel circuit units, the one of the pixel circuit units including the one of the thin film transistors, one of a plurality of second thin film transistors, and one of a plurality of capacitors; an opposite electrode that faces the pixel electrodes and that transmits light; an organic light emission layer that is interposed between the pixel electrodes and the opposite electrode to emit light; a first electrode on a second surface of the substrate; second electrodes facing the first electrode, the second electrodes being only in the separate pixel regions and overlapping an entirety of the pixel circuit units, respectively; and a light transmission adjusting layer between the first electrode and the second electrode.
