Abstract
A touch panel according to the embodiment includes a substrate, a recess part on the substrate, an electrode unit aligned on the substrate to detect an input position and an actuator aligned on the recess part to transfer vibration force. A liquid crystal display according to the embodiment includes a liquid crystal panel for displaying images; and a touch panel aligned at a display side of the liquid crystal panel such that information is input thereto from an outside. The touch panel includes an input unit for inputting the information; and a haptic unit for applying vibration. The input unit includes a first substrate; a sensor unit aligned on the first substrate to detect an input position; and a wiring electrically connected to the sensor unit. The haptic unit includes a second substrate on the first substrate; a recess part on one surface of the second substrate; an electrode unit aligned on the second substrate to receive position information; and an actuator aligned on the recess part to transfer vibration force.
