摘要： A liquid crystal display capable of preventing a residual image phenomenon from occurring after power is cut off. The liquid crystal display includes: a voltage generating unit outputting a gate-on voltage to a first output node, outputting a gate-off voltage to a second output node, and pulling up the voltage level of the second output node to a level of a positive discharge voltage after a power supply voltage is cut off; a gate driving unit sequentially supplying the gate-on voltage and the gate-off voltage; a data driving unit supplying an image data voltage; and a liquid crystal panel including a plurality of pixels that are turned on or off according to the gate-on voltage or the gate-off voltage, so as to display an image corresponding to the image data voltage.
