Claim 0:
1. A liquid crystal device comprising:
a first liquid crystal cell; and
a second liquid crystal cell overlapping the first liquid crystal cell, wherein
each of the first liquid crystal cell and the second liquid crystal cell comprises:
a first transparent substrate;
a first alignment film;
a first strip electrode and a second strip electrode located between the first transparent substrate and the first alignment film, arranged at an interval, and configured to have mutually different voltages applied thereto;
a second transparent substrate;
a second alignment film;
a third strip electrode and a fourth strip electrode located between the second transparent substrate and the second alignment film, arranged at an interval, and configured to have mutually different voltages applied thereto; and
a liquid crystal layer located between the first alignment film and the second alignment film, wherein
an extension direction of each of the first strip electrode and the second strip electrode in the first liquid crystal cell is different from an extension direction of each of the first strip electrode and the second strip electrode in the second liquid crystal cell, and
in each of the first liquid crystal cell and the second liquid crystal cell, an alignment treatment direction of the first alignment film intersects with an alignment treatment direction of the second alignment film at an angle smaller than or equal to 90°, and the extension direction of each of the first strip electrode and the second strip electrode intersects with an extension direction of each of the third strip electrode and the fourth strip electrode at an angle other than 90°.
