ABSTRACT:
A color liquid crystal exposure apparatus includes a color light source for emitting a plurality of colored light beams, a liquid crystal shutter having a plurality of liquid crystal pixels arrayed in a direction orthogonal to the direction of the relative movement, and a driving circuit for switching the color light source from one color to another, and for driving the plurality of liquid crystal pixels. The plurality of liquid crystal pixels are divided into a plurality of pixel groups. The liquid crystal pixels in each pixel group are arrayed, one displaced from another by a prescribed distance, in the direction orthogonal to the direction of the relative movement. The driving circuit drives the plurality of liquid crystal pixels in time-division fashion so that the liquid crystal pixels having the same displaced position in the plurality of pixel groups are driven at one time.
