Abstract:
1. An organic light emitting display device comprising: a substrate having a transmitting region and a plurality of pixel regions separated from each other by the transmitting region, wherein the transmitting region is configured to transmit light therethrough, wherein the pixel regions are configured to display an image, and wherein the substrate has first and second surfaces opposing each other; a plurality of thin film transistors formed in each of the pixel regions over the first surface of the substrate; a passivation film covering the thin film transistors; a pixel defining layer formed over the passivation film, wherein the pixel defining layer is not formed directly above any portion of each of the thin film transistors; a plurality of pixel electrodes formed on the passivation film, wherein each of the pixel electrodes is electrically connected to and formed substantially directly above the corresponding thin film transistor, wherein each of the pixel electrodes is formed only in the corresponding pixel region, and wherein the pixel electrodes are separated from each other; an organic light emitting layer formed on each of the pixel electrodes and configured to emit light; a facing electrode formed on the organic light emitting layer and configured to transmit light; a first electrode formed on the second surface of the substrate; a solar cell active layer formed on the first electrode; and a second electrode formed on the solar cell active layer, wherein the first electrode is closer to the substrate than the second electrode.
