An optical element includes a first liquid crystal cell and a second liquid crystal cell. The first liquid crystal cell and the second liquid crystal cell are stacked. Each of the first liquid crystal cell and the second liquid crystal cell includes a first substrate on which a first transparent electrode and a second transparent electrode are alternately and repeatedly arranged in a first direction, a second substrate on which a third transparent electrode and a fourth transparent electrode are alternately and repeatedly arranged in a second direction intersecting the first direction, and a liquid crystal layer between the first substrate and the second substrate. The second substrate of the first liquid crystal cell and the first substrate of the second liquid crystal cell are adjacent to each other.
