Abstract
The display device includes a substrate including first and second sub pixels, a first electrode patterned in each of the first and second sub pixels on the substrate, a first emission layer in each of the first and second sub pixels on the first electrode to emit first colored light, a second electrode in each of the first and second sub pixels on the first emission layer, a second emission layer on the second electrode to emit second colored light, and a third electrode on the second emission layer. The first electrode of the first sub pixel is relatively larger than the first electrode of the second sub pixel, the first electrode of the first sub pixel is electrically connected with the second electrode of the first sub pixel, and the first electrode of the second sub pixel is insulated from the second electrode of the second sub pixel.
