Abstract
According to one embodiment, a liquid crystal optical apparatus includes a first substrate unit, a second substrate unit, and a liquid crystal layer. The first substrate unit includes a first substrate having a first major surface and first electrodes provided on the first major surface to extend along a first direction, and arranged in a direction non-parallel to the first direction. The second substrate unit includes a second substrate having a second major surface opposing the first major surface and a second electrode provided on the second major surface to oppose the first electrodes. The liquid crystal layer is provided between the first and second substrate units. One of the first electrodes includes a first main body portion and a first tip portion. The first main body portion extends along the first direction, and the first tip portion is provided at a tip of the first main body portion.
