PROBLEM TO BE SOLVED: To suppress unevenness of residual DC component in AC driving and prevent a display from getting burnt by letting liquid crystal capacitance and auxiliary capacitance satisfy a specific relation. SOLUTION: Liquid crystal capacitance CLC in which initial alignment of liquid crystal is controlled vertically to a substrate for each picture element and auxiliary capacitance connected with the liquid crystal capacitance CLC in parallel are formed. The auxiliary capacitance CSC consisting of a p-Si film 14, an auxiliary capacitance electrode 12, and a gate insulating film 13 is set so as to satisfy a relation, 0.61×CLC<=CSC<=2.0×CLC, with the liquid crystal capacitance CLC consisting of picture element electrode 20, common electrode 33, and liquid crystal 40. Thus, in a vertical alignment type, resultant capacitance of the liquid crystal capacitance CLC and the auxiliary capacitance CSC becomes sufficiently large by making the auxiliary capacitance CSC 0.61 times as large as the liquid crystal capacitance CLC or more. Therefore, burning phenomenon is prevented from occurring even if ON-OFF ratio of the liquid crystal capacitance becomes large.
