Patent ID: 8692817

Claim:
An organic light-emitting display device, comprising: a first sub-pixel, a second sub-pixel, and a third sub-pixel on a substrate; and a transmission region commonly formed on the first sub-pixel, the second sub-pixel, and the third sub-pixel, the transmission region transmitting external light; wherein: each of the first, second, and third sub-pixels includes: a pixel circuit unit adjacent to the transmission region and including at least one thin film transistor (TFT); a first pixel electrode electrically connected to the TFT of the pixel circuit unit, the first pixel electrode overlapping the pixel circuit unit to cover the TFT and including a reflective film formed of a conductive material that permits light reflection; a second pixel electrode in the transmission region, the second pixel electrode being electrically connected to the first pixel electrode and being formed of a conductive material that permits light transmission; and a counter electrode that faces the first pixel electrode and the second pixel electrode; the first sub-pixel includes a first organic film between the counter electrode and the first and second pixel electrodes of the first sub-pixel, and comprises a red light-emitting layer, the second sub-pixel includes a second organic film between the counter electrode and the first and second pixel electrodes of the second sub-pixel, and comprises a green light-emitting layer, and the third sub-pixel includes a third organic film between the counter electrode and the first and second pixel electrodes of the third sub-pixel, and comprises a blue light-emitting layer.
