Abstract
A display apparatus includes a display panel and a touch sensing unit disposed on the display panel. The touch sensing unit includes a touch sensor and a first pressure sensor. The touch sensor includes a first touch electrode layer and a second touch electrode layer disposed on the first touch electrode layer. The first pressure sensor includes: a transmission pressure electrode, a sensing pressure electrode separated from the transmission pressure electrode, and a piezoresistive pattern contacting each of the transmission pressure electrode and the sensing pressure electrode. Each of the transmission pressure electrode and the sensing pressure electrode is disposed in a same layer as any one of the first touch electrode layer and the second touch electrode layer.
