Abstract
An optical element includes first to fourth liquid crystal cells. Each of the first to fourth liquid crystal cells includes a first substrate on which a first pair of comb-shaped transparent electrodes are arranged and a second substrate on which a second pair of comb-shaped transparent electrodes are arranged. An extending direction of the first pair of comb-shaped transparent electrodes is orthogonal to an extending direction of the second pair of comb-shaped transparent electrodes. Between two different liquid crystal cells of the first to fourth liquid crystal cells, one of the first pair of comb-shaped transparent electrodes of one liquid crystal cell and one of the second pair of comb-shaped transparent electrodes of the other liquid crystal cell are electrically connected to each other.
