Abstract
According to one embodiment, a liquid crystal optical apparatus includes first and second substrate units, a liquid crystal layer, and a drive unit. The first substrate unit includes a first substrate having a first major surface, a plurality of first and second electrodes. The first electrodes are provided on the first major surface to extend in a first direction. The second electrodes are provided on the first major surface to extend in the first direction. The second substrate unit includes a second substrate having a second major surface opposing the first major surface and an opposing electrode. The opposing electrode is provided on the second major surface. The liquid crystal layer is provided between the first and second substrate units. The drive unit is electrically connected to the first and second electrodes, and the opposing electrode and forms a refractive index distribution in the liquid crystal layer.
