    • In a color liquid crystal exposure apparatus equipped with a liquid crystal shutter comprising a single array of liquid crystal pixels, a cost reduction is achieved by reducing the number of control ICs required to control the liquid crystal pixels in the liquid crystal shutter. The liquid crystal exposure apparatus for exposing a photosensitive member, during a relative movement thereof, comprises: 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, wherein the plurality of liquid crystal pixels are divided into a plurality of pixel groups of N liquid crystal pixels each, the N liquid crystal pixels in each pixel group being arrayed, one displaced from another by a prescribed distance, in the direction orthogonal to the direction of the relative movement, and 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.
