Abstract
Disclosed is a display device which may achieve process simplification and cost reduction. In the display device having touch sensors, the touch sensors are arranged on an encapsulation unit arranged to cover light emitting elements, and an anti-reflective film including a photosensitive material and a black pigment is arranged on routing lines connected to the touch sensors and a conductive layer arranged as an uppermost layer among a plurality of conductive layers included in the touch sensors. Thereby, visibility of external light may be improved by the anti-reflective film, and the touch electrodes are arranged on an encapsulation unit without a separate attachment process and, thus, process simplification and cost reduction of the display device may be achieved.
