Abstract
An n-th stage (wherein, n is an integer) of the stages of a gate driving circuit includes a pull-up part, a first variable mode part and a second variable mode part. At least one of the first and second variable mode parts includes a variable element. The variable element comprises a first thin-film transistor (TFT) turned on in response to a first level voltage of the first or second direction signal, a second TFT applying the first or second direction signal to a control part of the pull-up part in response to an output signal of a previous stage or an output signal of a next stage, and a third TFT connected to the second TFT through the first TFT.
