Abstract
A liquid crystal shutter that realizes a high speed response and that solves a problem in which light leakage cannot be alleviated is provided. An alignment film coated on substrateadjacent to another liquid crystal device of substrates () and () of each of liquid crystal devices () is horizontal alignment film () and alignment film coated on the other substrate () is vertical alignment film (). A alignment treatment is performed on the horizontal alignment film coated on substrate () of liquid crystal device () having a polarizer () in a direction parallel to a light transmission axis of analyzer () and an alignment treatment is performed on the horizontal alignment film coated on substrate () of liquid crystal device () having analyzer () in a direction parallel to the light transmission axis of polarizer (). Liquid crystal materials () of liquid crystal devices () have a positive dielectric anisotropy and have twisting directions that is the reverse of each other.
