<P>PROBLEM TO BE SOLVED: To provide a gate driver which increases picture quality by eliminating deterioration in stages, and also permits long-life driving. <P>SOLUTION: The gate driver relating to this invention is provided with two or more stages which sequentially output shifted signals. Each of the two or more stages comprises: a 1st control part 21 to control a 1st node in response to a 1st scan signal and a 2nd scan signal; a 2nd control part 23 to control a 2nd node and a 3rd node in response to the 1st scan signal and the voltage on the 1st node; and an output part 25 to selectively output any of a 1st power source voltage and two or more clock signals in response to the voltages on the 1st through the 3rd node. Switching is carried out between a 2nd power source voltage and a 3rd power source voltage which are different from each other and supplied to the 2nd node and the 3rd node, respectively. <P>COPYRIGHT: (C)2007,JPO&INPIT |
