Claim 3:
4. The optical element according to claim 1,
wherein 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 a first 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 include, in the second substrate, a third 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 fourth comb-teeth electrode overlapping the third comb-teeth electrode via a second 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,
an extension direction of the third comb-teeth electrode is perpendicular to an extension direction of the fourth comb-teeth electrode, and
the extension direction of the first comb-teeth electrode is oblique to the extension direction of the third comb-teeth electrode.
