Abstract
A gate signal line driving circuit which suppresses noises in a gate signal and a display device which uses the gate signal line driving circuit are provided. A first basic circuit provided to a gate signal line driving circuit includes a HIGH voltage applying switching element which applies a HIGH voltage to gate signal lines in response to a signal HIGH period, and a LOW voltage applying switching circuit which applies a LOW voltage to the gate signal lines in response to a signal LOW period. In response to a signal HIGH period, a switch of the LOW voltage applying switching circuit of the first basic circuit is turned off based on a signal applied to a switch of the HIGH voltage applying switching element of a second basic circuit which assumes a signal HIGH period earlier than the first basic circuit.
