Abstract:
To provide a liquid crystal display device with a touch detection function in which any drive method can be adopted. The liquid crystal display device is provided with: a liquid crystal element arrangement that has a plurality of liquid crystal display elements arranged in a matrix shape; a plurality of scanning lines that are arranged in each row of the liquid crystal element arrangement, and supply scanning signals to a plurality of liquid crystal display elements arranged in a corresponding row; a plurality of signal lines that are arranged in each column of the liquid crystal element arrangement, and supply an image signal to a plurality of liquid crystal display elements arranged in a corresponding column; a plurality of touch detection drive electrodes which are arranged in a column of the liquid crystal element arrangement, and to which a drive signal for detecting a touch is supplied; and a touch control part that specifies a touch detection drive electrode from the a plurality of touch detection drive electrodes. Here, the drive signal is supplied to the touch detection drive electrode specified by the touch control part.
