<P>PROBLEM TO BE SOLVED: To provide a gate driving circuit to improve driving defects and to provide a display apparatus having the circuit. <P>SOLUTION: The gate driving circuit comprises a shift register that has a plurality of stages cascade-connected to each other. An arbitrary m-th stage comprises: a pull-up section outputting a first clock signal as a gate signal in response to a first node signal converted into a high level by a first input signal; a pull-down section discharging the gate signal to an off-voltage in response to a second input signal; a discharging section discharging the first node signal to the off-voltage in response to the second input signal; a first holding section responsive to the first clock signal, maintaining the first node signal at the off-voltage of the discharged gate signal; and a second holding section responsive to the second clock signal, maintaining the first node signal at the off-voltage of the first input signal, wherein a width-to-length ratio of a transistor constituting the second holding section is greater than a width-to-length ratio of a transistor constituting the first holding section. <P>COPYRIGHT: (C)2008,JPO&INPIT |
