A liquid crystal display device comprises: a first data line extending in a first direction; a first pixel electrode and a second pixel electrode that are arranged in the first direction; a first transistor connected to the first pixel electrode; a second transistor connected to the second pixel electrode; and a first gate line electrically connected to the first transistor and the second transistor, wherein in the first pixel electrode, a first length along the first direction is shorter than a second length along a second direction perpendicular to the first direction, and the first pixel electrode includes at least one slit, and the slit extends at an angle of less than or equal to 45 degrees with respect to the second direction.
