A liquid crystal display device includes pixels, gate lines and source lines, active elements, a gate driver circuit, a source driver circuit, and a timing controller circuit. The source driver circuit conducts a prescribed operation of supplying the source signals of positive polarity and negative polarity having a prescribed voltage to the source lines during a vertical blanking interval, and electrically cutting the source lines off after the supply of the source signals while establishing a short circuit between adjoining source lines supplied with the source signals of opposite polarities, thereby causing the source lines to hold a prescribed DC voltage value.
