Abstract:
1. A liquid crystal shutter device comprising: a liquid crystal cell comprising a first substrate, a second substrate and liquid crystal sandwiched therebetween; pixel electrodes, which are signal electrodes, and lead-out electrodes provided on said first substrate; counter electrodes, which are common electrodes facing said pixel electrodes, provided on said second substrate; and a plurality of pixel rows comprising pixels each formed by an overlapped portion of said pixel electrode and said counter electrode, each of said pixel rows corresponding to image formation of a different color, the liquid crystal shutter device controlling light irradiation to a photosensitive member continuously and relatively moving in a direction orthogonal to said pixel rows, wherein a light shield film is provided separately for each of said pixel rows and overlaps each of said pixel rows, and wherein openings in said light shield film are provided at portions corresponding to said pixels.
