<P>PROBLEM TO BE SOLVED: To provide a gate signal line driving circuit which suppresses noise in a gate signal, and a display device using the same. <P>SOLUTION: The gate signal line driving circuit includes: 2n clock signal lines to which a 2n-phase clock signal is inputted in an order matching a normal order in the case of forward scan and is inputted in an order opposite to the normal order in the case of backward scan; and a plurality of fundamental circuits to which the 2n clock signal lines are connected and which output gate signals from output terminals. Each fundamental circuit includes: a high voltage application switching circuit of which the input side one clock signal line is connected to and which applies a voltage applied to this clock signal line, to the output terminal; and an off signal application switching circuit which applies an off voltage to a switch of the high voltage application switching circuit. Another clock signal line, to which a clock signal with an opposite phase is inputted, is connected to a switch of the off signal application switching circuit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
