Claim:
1. A liquid crystal optical device, comprising: a first substrate unit including a second substrate unit including a liquid crystal layer including liquid crystal molecules provided between the first substrate unit and the second substrate unit, a long axis of the liquid crystal molecules being aligned in a third direction when projected onto the plane, wherein the first side direction and the first direction form a first angle θ1 in a first rotation direction, the first angle being less than 90 degrees and more than 0 degrees, the first side direction and the second direction form a second angle θ2 in the first rotation direction, the second angle being different from the first angle, and being less than 90 degrees and more than 0 degrees, the first side direction and the third direction form a third angle θ3 in the first rotation direction, the third angle being different from the first angle and different from the second angle.
