Claim 4:
5. The optical element according to claim 1,
wherein the liquid crystal cell further includes a bistable alignment film providing stable alignment in two directions, between the first substrate and the liquid crystal layer,
the electrodes include, in the first substrate, a first comb-teeth electrode composed of a comb-teeth-shaped pixel electrode and a comb-teeth-shaped common electrode with comb teeth of these electrodes fitting each other, and include, in the second substrate, a second comb-teeth electrode composed of a comb-teeth-shaped pixel electrode and a comb-teeth-shaped common electrode with comb teeth of these electrodes fitting each other, and
in a plan view, an extension direction of the first comb-teeth electrode is oblique to an extension direction of the second comb-teeth electrode.
