Abstract

The present invention relates to a gate driver (10, 1042) including stages (ST). Each of the stages (ST) includes an input transistor (M1) that transmits an input signal (IN) to a Q node in response to a clock signal (CLK), a pull-up transistor (M5) that outputs a high gate voltage (VGH) as an output signal (OUT) in response to a signal of a QB node, a first pull-down transistor (M5) that outputs a low gate voltage (LGV) as the output signal (OUT) in response to a signal of the Q node, a first control transistor (M9) that transmits a signal of a QB node of a previous stage (ST) to a B node in response to the signal of the Q node, and a second pull-down transistor (M11) that outputs the low gate voltage (LGV) as the output signal (OUT) in response to a signal of the B node.
