Abstract
To improve surge tolerance of a shift register constituting a gate signal line driving circuit formed on a substrate of a flat panel display. A gate signal line driving circuit includes a shift register composed of a plurality of cascaded unit register circuits, and sequentially outputs gate signals to a plurality of gate signal lines. Of the unit register circuits, two register circuits positioned on the leading end side for the shift operation of the shift register receive a start signal in parallel to operate. The two register circuits respectively output signals to mutually different destinations such that an output signal from one of the two register circuits is inputted via a gate signal generation circuit to a gate signal line, while an output signal from the other register circuit is inputted into its downstream unit register circuit.
