Liquid crystal light control device

A liquid crystal light control device comprising:

• a first liquid crystal cell into which light, including a first polarized component having a first polarized axis in a first direction and a second polarized component having a second polarized axis in a second direction intersecting the first direction, is configured to enter;
• 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,
• wherein
• each of the first liquid crystal cell and the second liquid crystal cell includes:
• a first substrate including a first alignment film having an alignment direction in the second direction;
• a second substrate including an electrode having a strip pattern extending in the second direction and a second alignment film having an alignment direction in the first 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 second direction to the first direction from the first substrate side to the second substrate side,
• each of the third liquid crystal cell and the fourth liquid crystal cell includes:
• a first substrate including a first alignment film having an alignment direction in the first direction;
• a second substrate including an electrode having a strip pattern extending in the first direction and a second alignment film having an alignment direction in the second 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 direction to the second direction from the first substrate side to the second substrate side, and
• the first substrate of one or more liquid crystal cells selected from a group of the first liquid crystal cell, the second liquid crystal cell, the third liquid crystal cell, and the fourth liquid crystal cell has a flat plate electrode, and the first substrate of any remaining liquid crystal cells have a strip patterned electrode extending in a direction intersecting the extending direction of the electrode having the strip pattern of the second substrate.
