Abstract: PROBLEM TO BE SOLVED: To improve picture quality in a display image even when a data voltage applied period is short. SOLUTION: A gate line driver 34 applies a gate voltage to many pieces of gate lines G1-Gm successively for a prescribed period each. A data line is grouped to four groups (d1A-dnA: A group, d1B-dnB: B group, diC-DnC: C group, diD-dnD: D group) respectively consisting of (n) pieces of data lines, and a data line driver 40 and a multiplexer 38 apply a data voltage to respective data lines of prescribed data line group in the prescribed period successively for the data line groups A-D. A precharge controller 44 and a voltage switch circuit 46 apply a precharge voltage (+V1 or -V1 ) of the same polarity as the data voltage next applied to respective data lines to respective data line groups A-D through a transistor 42 between the time when the data voltage is applied the last time and the time the data voltage is applied next.
