Abstract: In a liquid crystal display (LCD) device having a touch panel function, power consumption is reduced in the standby state. The display section is divided into blocks each of which is formed of a plurality of display lines. The counter electrode is disposed for each block. A driving circuit selectively supplies, to the counter electrode of each block, the voltage used for the liquid crystal display and the voltage used for the touch panel scanning. The driving circuit has a source amplifier that supplies the video voltages to the video lines. The driving circuit reduces the current in the source amplifier, such that the current is lower than current at the time of a normal operation, to lower the power consumption, and stops the operation of the source amplifier and supplies the GND voltage to the video lines to further lower the power consumption.
