Abstract
A display apparatus includes a substrate including a first area, a second area, and a bending area, the bending area disposed between the first area and the second area and bending about a bending axis running along a first direction; a first piezoelectric device disposed over the bending area; and a pressure sensor. The first piezoelectric device is configured to contract or expand according to a pressure variation sensed by the pressure sensor.
