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.
