Abstract
The present invention provides a gate driver and liquid crystal display device. The gate driver, for driving scan lines of liquid crystal display device, includes: an input buffer, for receiving clock signal, first frame start pulse signal and second frame start pulse signal; shift register, including n+2 triggers, connected serially from the first trigger to the n+1trigger, a clock signal input terminal of the n+2trigger being connected to the clock signal transmission line, wherein n being a natural number, when the first frame start pulse signal starting, the shift register shifting vertical synchronization signal and outputting n+1 outputs of shift registers based on the clock signal; a voltage level shifter, for shifting the output of the shift register to predefined voltage level and outputting shifted result serially; and an output buffer, for applying output of voltage level shifter to scan lines.
