Abstract: A display device includes a display panel. An input sensor is disposed on the display panel. A first pattern of the input sensor includes mesh lines. A second pattern of the input sensor overlaps the first pattern with an insulating layer interposed therebetween, and includes mesh lines. The mesh lines of the first pattern include a first mesh line extending in the first reference direction, and the mesh lines of the second pattern include a second mesh line extending in the first reference direction and overlapping the first mesh line in a plan view. In a plan view, first cutting areas in which the first mesh line is partially cut and second cutting areas in which the second mesh line is partially cut do not overlap.
