LIQUID CRYSTAL DISPLAY DEVICE

摘要

In a liquid crystal display device with a touch panel function, a second substrate includes a detection electrode of a touch panel. Each pixel includes a pixel electrode and a counter electrode. The counter electrode is divided into a plurality of blocks. The divided counter electrode of each block is commonly installed at each pixel of a plurality of display lines which are continuously formed and is used as a scan electrode of the touch panel. A driving circuit supplies an opposite voltage and a touch panel scan voltage to the divided counter electrode of each block. The driving circuit controls the supply start timing of the touch panel scan voltage for the divided counted electrode of each block.
