According to one embodiment, a liquid crystal display device includes a first substrate, a second substrate, a liquid crystal layer, and a first drive module. A first source line is located between a first divisional electrode and a second divisional electrode. One frame period includes a first display period, a second display period, a sense period, and a first pre-charge period. The first drive module supplies a first image signal having a first polarity to the first source line in the first display period, supplies a first pre-charge signal having a second polarity to the first source line in the first pre-charge period, and supplies the first image signal having the first polarity to the first source line in the second display period. |

1. A liquid crystal display device comprising:
a first substrate comprising a common electrode including a first divisional electrode and a second divisional electrode arranged with a space between, and a first source line located between the first divisional electrode and the second divisional electrode; a second substrate opposed to the first substrate; a liquid crystal layer held between the first substrate and the second substrate; and a first drive module electrically connected to the first divisional electrode, the second divisional electrode and the first source line, wherein one frame period includes a first display period, a second display period following the first display period, a sense period between the first display period and the second display period, and a first pre-charge period between the first display period and the sense period, in the first display period, the first drive module supplies a common drive signal to the first divisional electrode and the second divisional electrode and supplies a first image signal having a first polarity to the first source line, in the first pre-charge period, the first drive module supplies the common drive signal to the first divisional electrode and the second divisional electrode and supplies a first pre-charge signal having a second polarity, which is different from the first polarity, to the first source line, in the sense period, the first drive module supplies a sensor drive signal to at least one of the first divisional electrode and the second divisional electrode, and in the second display period, the first drive module supplies the common drive signal to the first divisional electrode and the second divisional electrode and supplies the first image signal having the first polarity to the first source line. |
