<p>When a gate voltage having a rectangular-shaped pulse is supplied, the voltage of a pixel electrode is pulled down and fluctuated by a fall of the gate voltage due to a parasitic capacitor formed between a gate line and the pixel electrode, i.e. a so-called drop voltage is generated. As the drop voltage depends on a time constant of a change in the gate voltage, it can be diminished by smoothing the falling edge of the gate voltage. This is achieved by, for example, providing a current discharging transistor of a gate driver 8 with a small channel width to decrease the maximum current value. By utilizing such a gate voltage, a liquid crystal display device with a small drop voltage can be provided, even when the capacitance of the parasitic capacitor is great. <IMAGE></p> |
