Organic light emitting display device and method of manufacturing the same
View Patent ↗An organic light emitting display device and a method of manufacturing the same are disclosed. The organic light emitting display device includes a substrate on which first, second and third pixel units are arranged in row and column directions. To simplify manufacturing and reduce defects, the first, second and third pixel units are arranged so that each column of the display is formed of only one of the first, second, and third pixel units.
1. An organic light emitting display device, comprising:
a substrate comprising a plurality of areas arranged in rows and columns, wherein each column comprises a plurality of first pixel units, a plurality of second pixel units or a plurality of third pixel units;
a plurality of first electrodes formed on the areas wherein each electrode is formed in one of the plurality of first pixel units, in one of the plurality of second pixel units, or in one of the plurality of third pixel units;
a pixel defining layer formed on the substrate, wherein the pixel defining layer is patterned to have openings exposing the first electrodes;
a first continuous light emitting layer formed on and across more than one of the first electrodes and the pixel defining layer in the column of the plurality of first pixel units;
a second continuous light emitting layer formed on and across more than one of the first electrodes and the pixel defining layer in the column of the plurality of second pixel units;
a third continuous light emitting layer formed on and across more than one of the first electrodes and the pixel defining layer in the column of the plurality of third pixel units; and
a second electrode formed on the first, second, and third continuous light emitting layers.
2. The organic light emitting display device of claim 1 , wherein the first, second and third continuous light emitting layers are each patterned in a substantially rectangular shape.
3. The organic light emitting display device of claim 1 , wherein the first, second and third continuous light emitting layers are red, green and blue light emitting layers, respectively.
4. The organic light emitting display device of claim 1 , further comprising a thin film transistor connected to each of the first electrodes.
