Liquid crystal light control device

Abstract

A liquid crystal light control device includes at least one liquid crystal panel. The at least one liquid crystal panel includes a first substrate provided with a first electrode including a strip-like pattern, and a first alignment film covering the first electrode, a second substrate provided with a second electrode including a strip-like pattern, and a second alignment film covering the second electrode, and a liquid crystal layer disposed between the first substrate and the second substrate. The liquid crystal layer has a thickness of 10 μm or more and liquid crystal molecules are aligned in a twisted manner from a first substrate side toward a second substrate side. A pretilt angle of the liquid crystal molecules controlled by the first alignment film and the second alignment film is 2 degrees or more and less than 8 degrees.
