A liquid crystal display includes a system circuit, a source driver, a gate driver, and a plurality of pixel units. The system circuit is used for generating a first scan line clock signal, a second scan line clock signal, a first scan line control signal, and a second scan line control signal, based on a horizontal synchronous signal and a vertical synchronous signal. The source driver is used for generating a data signal voltage. The gate driver includes a first shift register, a second shift register and a plurality of logic circuits. The first shift register is used for generating a first gate-on signal in response to the first scan line control signal after the first scan clock signal is triggered. The second register is used for generating a second gate-on signal in response to the second scan line control signal after the second scan clock signal is triggered. The plurality of logic circuits electrically coupled to the first and second shift registers are used for selectively outputting a scan signal from the first and the second gate-on signals. The plurality of pixel units, whereby each pixel unit includes a transistor and a liquid crystal capacitor having liquid crystal molecules, and alignment of liquid crystal molecules in each liquid crystal capacitor is varied according to the data signal voltage when the transistor of each pixel unit is turned on by the scan signal from the gate driver.
