Liquid crystal display device with touch panel
Abstract:
A liquid crystal display device with a touch panel includes: pixel electrodes as a plurality of electrodes to each of which a potential corresponding to a gray-scale value is applied; common electrodes as a plurality of electrodes that extend in one direction; detection electrodes as a plurality of electrodes that extend in a direction different from the one direction and detect a contact position on the panel; a liquid crystal layer that is formed of a liquid crystal composition; and a drive pulse output unit that sequentially applies a potential for detecting a touch to drive electrodes as a plurality of electrodes of a portion of the common electrodes, wherein the drive pulse output unit can output a drive pulse to the drive electrode at plural different timings within one horizontal synchronizing period for display.
