A liquid crystal display (LCD) includes a plurality of pixels, a source driver and a gate driver, each pixel comprising a transistor, a storage capacitor, a pixel electrode, a common electrode coupled to a common voltage, and liquid crystal molecules located between the pixel electrode and the common electrode, the transistor conducting a grey-scale signal generated by the gate driver to the pixel electrode based on a scan voltage generated by the gate driver, the LCD being characterized in that a substrate electrode of the transistor is coupled to a first voltage, and the storage capacitor is coupled to a substrate voltage and the transistor. The common voltage is positive proportional to the substrate voltage.
