Abstract
A display device includes a display panel and an input sensor. The input sensor may include a first sensing electrode, a signal line electrically connected to a first terminal of the first sensing electrode, a first line at least partially overlapping the first sensing electrode and extending in the same direction as the first sensing electrode in the active area, and a first switching element defining a first current path in the first sensing electrode and the first line or blocking the first current path.
