A light-emitting device includes an organic light-emitting layer, a first electrode disposed at one side of the organic light-emitting layer, and a second electrode disposed at the same side of the organic light-emitting layer as the first electrode. The first electrode is spaced apart from the second electrode. A display panel includes a substrate including a display region and a touch sensing region defined along a substrate-horizontal direction, at least one light-emitting device disposed over the substrate in the display region, and at least one touch sensor disposed over the substrate in the touch sensing region. The display region and the touch sensing region are not overlapped.
