Abstract: A display device includes light emitting elements in an active area and each light emitting element includes an anode, a light emitting layer, and a cathode; signal lines in a non-active area outside the active area; an encapsulation unit on the light emitting elements and the signal lines; touch electrodes on the encapsulation unit in the active area; first lines on the encapsulation unit in the non-active area and electrically connected to the touch electrodes; a second line outside the first lines; first auxiliary lines under the first lines and respectively electrically connected to a part of the first lines through first electrodes; and a second auxiliary line under the second line and electrically connected to the second line through a second electrode. The cathode is on an entire surface of the active area and extends to a shielding area of the non-active area.
