Abstract: An organic light emitting display and a method of manufacturing the same. The organic light-emitting display is a transparent display where one can see through the display to view an image on the other side of the display. Each pixel of the display has a first region that includes an organic light emitting diode and a thin film transistor, and a larger second region that is transparent. The second region is made of either transparent layers or ultra-thin layers so that light is not blocked. A second electrode of the display may include magnesium and may be produced by a selective deposition process, so that use of a fine metal mask may be avoided.

Abstract: An organic light emitting display device having high transmittance with respect to external light and a method of manufacturing the same. The organic light emitting display device includes a substrate; a plurality of pixels formed on the substrate, each of the pixels including a first region that emits light and a second region that transmits external light; a plurality of thin film transistors disposed in the first region of each pixel; a plurality of first electrodes disposed in the first region of each pixel and electrically connected to the thin film transistors, respectively; a second electrode formed opposite to the plurality of first electrodes and comprising a plurality of transmission windows corresponding to the second regions; and an organic layer formed between the first electrodes and the second electrode. The transmission windows can be formed in the second electrode, that is, a cathode.
