Abstract: A thin and lightweight display device is disclosed. An organic light-emitting display device having a touch sensor is configured such that a color filter array, which is disposed between an encapsulation unit and the touch sensor, extends to a pad area to contact the touch pad, thereby reducing stress on the pad area, and such that touch electrodes are disposed on the encapsulation unit, with the result that an additional bonding process is not required, whereby the process is simplified and cost is reduced.

Abstract: An organic electroluminescent display device including first to fourth pixel regions each including red, green and blue sub-pixel regions, each of the first to fourth pixel regions being divided into first and second columns, the first column being divided into first and second rows. A red sub-pixel region and a green sub-pixel region are respectively arranged in the first and second rows, and a blue sub-pixel region is arranged in the second column. A red emitting layer is formed in the red sub-pixel region; a green emitting layer is formed in the green sub-pixel region; and a blue emitting layer is formed in the blue sub-pixel region.
