Abstract
A gate signal line driving circuit includes plural basic circuits, each outputting to a gate signal line a gate signal which is high during a high signal period and low during a low signal period. Each of the basic circuits includes: a gate line high voltage application circuit which is turned on in accordance with the high signal period to apply the high voltage to the gate signal line; a gate line low voltage application circuit which is turned on in accordance with the low signal period to apply the low voltage to the gate signal line; and a second gate line low voltage application circuit which is turned on to apply the low voltage to the gate signal line in at least a part of a period between turning off the gate line high voltage application circuit and turning on the gate line low voltage application circuit.
