A gate line driving circuit includes a shift register section that selects gate lines for gradation display and for black insertion, and an output circuit that outputs a driving signal to the gate line which is selected by the shift register section. In particular, the output circuit is configured to obtain an overlap between an output period of a driving signal to each selected gate line and an output period of a driving signal to a gate line that is driven in precedence to the selected gate line, and independently control a first preliminary driving period corresponding to the overlap for gradation display and a second preliminary driving period corresponding to the overlap for black insertion.
