Claim Text:
1. A liquid crystal optical element comprising: a first substrate unit including: a second substrate unit including: a liquid crystal layer provided between the first substrate unit and the second substrate unit, the liquid crystal layer having a refractive index distribution when voltages are applied between the first electrodes and the opposing electrode, between the second electrodes and the opposing electrode, and between the third electrodes and the opposing electrode, the refractive index distribution having a plurality of lens shape portions, each of the lens shape portions being provided between each of the first electrodes; and a plurality of spacers being in contact with the liquid crystal layer between the first substrate unit and the second substrate unit, and defining a distance between the first substrate unit and the second substrate unit, a diameter of each spacer being larger than the first width, one of the second electrodes-including: the one of the third electrodes-including:
