Abstract:
There are provided a touch sensor and a liquid crystal display including the same. A touch sensor includes a plurality of driving electrodes, a plurality of sensing electrodes intersecting the driving electrodes, a plurality of piezoelectric materials disposed between the driving electrodes and the sensing electrodes at intersection points of the driving electrodes and the sensing electrodes, and a touch controller for detecting a touch position and a touch pressure by using sensing signals output from the sensing electrodes.
