Claim:
1. An alignment device for a polymer stabilized vertical alignment liquid crystal panel, the polymer stabilized vertical alignment liquid crystal panel comprising a first substrate, a second substrate, and a liquid crystal layer, the first substrate comprising a common electrode, the second substrate comprising a pixel electrode, the liquid crystal layer comprising negative liquid crystal molecules and ultraviolet-curable resin, wherein the alignment device comprises: a voltage application module, which applies an electrical voltage that exceeds a rotation threshold of the liquid crystal layer to the common electrode and the pixel electrode; a light source, which comprises at least two ultraviolet light sources that are distributed parallel in a first direction that is inclined with respect to the polymer stabilized vertical alignment liquid crystal panel and are spaced from each other in the first direction, the at least two ultraviolet light sources being spaced from the polymer stabilized vertical alignment liquid crystal panel by different distances so that a first one of the at least two ultraviolet light sources is spaced from the polymer stabilized vertical alignment liquid crystal panel by a first distance and a second one of the at least two ultraviolet light sources is spaced from the polymer stabilized vertical alignment liquid crystal panel by a second distance that is greater than the first distance, the ultraviolet light sources extending in a second direction and emitting ultraviolet lights of different intensities to irradiate the polymer stabilized vertical alignment liquid crystal panel, wherein the first one of the at least two ultraviolet light source emits ultraviolet light at a first intensity and the second one of the at least two ultraviolet light source emits ultraviolet light at a second intensity that is greater than the first intensity; and a light source movement control module, which controls the light source to reciprocally move in such a direction as to have accumulation of ultraviolet light received by the ultraviolet-curable resin of the liquid crystal layer homogenized.
