Abstract

A display device includes a display unit having a display area with a first hole formed therein, and an input sensing unit which is disposed on the display unit and having a second hole corresponding to the first hole. the input sensing unit includes a base layer which includes: an adjacent area adjacent to the second hole; and a sensing area overlapping the display area, detection electrodes disposed on the sensing area; and a first connection wiring disposed on the adjacent area and that electrically connects at least two detection electrodes spaced apart by the second hole, disposed at respective sides of the second hole. The display unit includes dams disposed adjacent to the first hole, each of the dams forming a closed loop along edges of the first hole. The first connection wiring overlaps at least one of the dams.
