Abstract: A thin and lightweight display device is disclosed. The display device includes a black bridge electrically connected to a plurality of touch electrodes disposed on an encapsulation unit, wherein the black bridge is disposed on the encapsulation unit between color filters to also serve as a black matrix, with the result that a cell gap between the black bridge and an anode electrode is reduced when compared with a comparative example, thereby securing a wide viewing angle, and wherein the 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.
