Abstract: A display device includes a first base layer defining a display area in which pixels are arranged, a second base layer at least partially under the first base layer, a first connection signal line partially on the first base layer, and a second connection signal line partially under the second base layer. The first connection signal line includes a (1-1)st part overlapping the first base layer in a plan view and a (1-2)st part that does not overlap the first base layer in the plan view. The second connection signal line includes a (2-1)st part overlapping the second base layer in the plan view and a (2-2)st part that does not overlap the second base layer in the plan view. At least a portion of the (2-2)st part overlaps the (1-2)st part in the plan view, and the (1-2)st part and the (2-2)st part are electrically connected.

Abstract: A display device includes a display panel. The display panel includes a pixel, an encapsulation layer, and a connection electrode connecting a signal line and a pad electrode. The connection electrode is connected to the pad electrode via a first contact area positioned in a non-display area. A first contact hole is defined penetrating the second synthetic resin layer in the first contact area, a plurality of insulating layers is disposed in the first contact hole, and a second contact hole is defined inside the first contact hole in a plan view, penetrates the insulating layers, and exposes the pad electrode. The first contact hole has a width greater than a width of the second contact hole in the plan view.
