PROBLEM TO BE SOLVED: To provide a driving circuit of a liquid crystal display device for solving the problem of the time required for electrical charge/discharge of a source line and also solving the problem of power consumption due to a short-circuit by precharge. SOLUTION: The driving circuit of a liquid crystal display device is provided with a first short-circuit means 11, a second short-circuit means 12, a third short-circuit means 13, and a fourth short-circuit means 14. By using especially the fourth short-circuit means 14, source line drive can be performed from a prescribed potential generated by a gradation voltage generation circuit 16. Also, by changing the drive start potential from the conventional common electrode potential Vcom into the potential generated by the gradation voltage generation circuit 16, power consumption can be effectively reduced (by approximately 8% on average compared with that in the conventional manner).
