A liquid crystal includes: a gate line which extends substantially in a first direction, a step-down gate line which extends substantially in the first direction; a data line which extends substantially in a second direction and crosses the gate line; a first thin film transistor connected to the gate line and the data line; a second thin film transistor connected to the gate line and the data line; a third thin film transistor connected to the gate line and the second thin film transistor; a reference voltage line connected to the third thin film transistor; a fourth thin film transistor connected to the step-down gate line, the second thin film transistor and the third thin film transistor; and a pixel electrode including first, second and third subpixel electrodes connected to the first, second and third thin film transistors, respectively.
