Claim:
1. A method for aligning liquid crystals of a PSVA liquid crystal display device, including the following steps: providing a first voltage to a gate of a thin film transistor corresponding to each pixel unit for enabling the thin film transistor in a turn-on state; applying a second voltage to a source of the thin film transistor corresponding to each pixel unit, and applying a third voltage to a color filter side common electrode and an array side common electrode, so as to generate an alternating current voltage difference between the source and the color filter side common electrode during alignment of liquid crystal molecules, and enable the liquid crystal molecules to be aligned according to predefined direction angles; and curing the liquid crystal molecules aligned according to the predefined direction angles through energy light; wherein the first voltage is a continuous direct current voltage which can enable the thin film transistor in a turn-on state; wherein the source of the thin film transistor is grounded, and the third voltage is an alternating current voltage.
