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