A liquid crystal display device with a touch panel includes: pixel electrodes which is applied a electrical potential corresponding to a gradation value in respective pixels; common electrodes that are a plurality of electrodes which extend in one direction; a liquid crystal layer having a liquid crystal composition whose orientation is changed according to an electric field developed by the pixel electrodes and the common electrodes; and detection electrodes that are a plurality of electrodes which extend in another direction different from the one direction, and detect a touch position on the panel. The common electrodes include a first electrode which is applied a detection potential for detecting the touch position on the panel, and a second electrode to which a potential different from the detection potential is applied during a period in which the detection potential is applied. |
