Abstract

A display apparatus includes a first substrate; a pixel array layer disposed on the first substrate and defining a display area and a non-display area, and the pixel array layer including a pixel signal line; a second substrate disposed opposite to the first substrate; a display medium disposed between the first substrate and the second substrate; and an ultrasonic element (UE) layer, disposed on the second substrate and including an ultrasonic signal line. Within at least parts of the display area corresponding to the ultrasonic element layer, a projection area on the first substrate by projecting the ultrasonic signal line along the normal direction of the first substrate at least partially overlaps with another projection area on the first substrate by projecting the pixel signal line along the normal direction of the first substrate.
