Abstract:
In a liquid crystal display device with a touch panel function, a second substrate has detection electrodes of a touch panel, each pixel has a pixel electrode and a counter electrode, the counter electrode is divided into a plurality of blocks, and the counter electrodes of the respective divided blocks are shared to the respective pixels of a plurality of display lines side by side, the counter electrodes of the respective divided blocks is also used as scanning electrodes of the touch panel, and a driver circuit is provided to apply a counter voltage and a touch panel scanning voltage to the counter electrodes of the respective divided blocks, and the driver circuit can adjust a supply start timing of the touch panel scanning voltage to be applied to the counter electrodes of the respective divided blocks.
