Claim 2:
3. The optical element according to claim 1,
wherein the liquid crystal cell further includes a weak anchoring horizontal alignment film between the first substrate and the liquid crystal layer and a vertical alignment film between the liquid crystal layer and the second substrate,
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 a second comb-teeth electrode overlapping the first comb-teeth electrode via an insulating layer and 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 perpendicular to an extension direction of the second comb-teeth electrode.
