Abstract
Each stage of a gate driver includes a controlling part which increases an electric potential of a boosting line in response to a carry signal of a previous stage and decreases the electric potential of the boosting line in response to the carry signal of a next stage, a first output part which turns on in response to the increased electric potential of the boosting line and receiving a clock signal to output a gate signal of a present stage, and a second output part which turns on in response to the increased electric potential of the boosting line and receiving the clock signal to output the carry signal of the present stage. The boosting line of the present stage is disposed adjacent to a gate line which is connected to one of next stages following the present stage.
