Liquid crystal light control device

A liquid crystal light control device, comprising:

• a first liquid crystal cell;
• a second liquid crystal cell overlapping the first liquid crystal cell;
• a third liquid crystal cell overlapping the second liquid crystal cell;
• and
• a fourth liquid crystal cell overlapping the third liquid crystal cell;
• each of the first liquid crystal cell, the second liquid crystal cell, the third liquid crystal cell, and the fourth liquid crystal cell include:
• a first substrate arranged with a first electrode having a strip pattern and a first alignment film, a first alignment direction of the first alignment film intersecting a longitudinal direction of the strip pattern of the first electrode;
• a second substrate arranged with a second electrode having a strip pattern and a second alignment film, a second alignment direction of the second alignment film intersecting a longitudinal direction of the strip pattern of the second electrode and the first alignment direction;
• and
• a liquid crystal layer between the first substrate and the second substrate, a long axis direction of liquid crystal molecules in the liquid crystal layer aligned according to both of the alignment directions of the first and second alignment films so as to rotate horizontally from the first alignment direction of the first alignment film to the second alignment direction of the second alignment film from the first substrate side to the second substrate side,
• wherein:
• the first substrate and second substrate are arranged with the longitudinal directions of the strip patterns of the first electrode and second electrode intersecting, and
• two of the first liquid crystal cell, the second liquid crystal cell, the third liquid crystal cell, and the fourth liquid crystal cell are arranged with the longitudinal direction of the strip pattern of the first electrode parallel to a first direction, and the longitudinal direction of the strip pattern of the first electrode of the other two liquid crystal cells is parallel to a second direction that intersects the first direction.
