Abstract:
A liquid crystal display device with a touch panel includes: display drive circuits that are disposed respectively at the outsides of the sides opposing to a display region, and that apply sequential scanning signal potentials to scanning signal lines; touch panel drive circuits that are disposed respectively further to the outsides of the display drive circuits, and that apply sequential drive pulses to a plurality of drive electrodes among common electrodes; and switching circuits that are disposed respectively at insides of the display drive circuits, and that switch between applying common electric potentials for controlling the alignment of the liquid crystal composition and applying a touch drive pulse that detects the touching to the display surface.
