Abstract
A liquid crystal optical device includes a liquid crystal optical unit and a drive unit. The liquid crystal optical unit includes a first and second substrate unit, and a liquid crystal layer. The first substrate unit includes a first substrate, a plurality of first electrodes, a second electrode, and a third electrode. The second substrate unit includes a second substrate, a plurality of first opposing electrodes, a second opposing electrode, and a third opposing electrode. The drive unit is configured to implement a first operation including subjecting the first electrodes to a first potential, subjecting the second electrode to a second potential, subjecting the third electrode to a third potential, subjecting the first opposing electrodes to a first opposing potential, subjecting the second opposing electrode to a second opposing potential, and subjecting the third opposing electrode to a third opposing potential.
