Abstract
An optical device comprises a first liquid crystal cell, a second liquid crystal cell overlapped with the first liquid crystal cell. Each of the first liquid crystal cell and the second liquid crystal cell includes a first substrate arranged with a first electrode extending in a direction inclined at a predetermined angle with respect to a first direction, a second substrate arranged with a second electrode extending in a direction inclined at a predetermined angle with respect to a second direction, and a liquid crystal layer. An extension direction of the first electrode and an that of the second electrode intersect each other without being perpendicular. The extension directions of the first electrode and the second electrode in the first liquid crystal cell and that of the first electrode and the second electrode in the second liquid crystal cell are different from each other.
