Abstract: A liquid crystal display device with a plurality of pixels arranged in a matrix includes a first substrate, a second substrate, a liquid crystal interposed between the first and the second substrates, and a detection circuit. The second substrate includes a detection electrode for a touch panel. The respective pixels have pixel electrodes and counter electrodes. The counter electrode divided into a plurality of blocks is provided common to the respective pixels on a plurality of consecutive display lines. The counter electrode divided into blocks serves as the scanning electrode for the touch panel. The detection circuit includes a calibration capacity element provided for each of the detection electrodes, is having one end connected to the detection electrode, and supplies a calibration voltage to the other end of the calibration capacity element in a touched position detection process.
