Abstract
According to one embodiment, a liquid crystal optical device includes first and second substrate units and a liquid crystal layer. The first substrate unit includes a first substrate having a first major surface, and a first electrode extending along a first direction. The second substrate unit includes a second substrate and a first opposing electrode. The liquid crystal layer is provided between the first substrate unit and the second substrate unit and includes a first portion provided on a side of the first substrate unit and a second portion provided on a side of the second substrate unit. The first portion has a vertical alignment. The second portion has a horizontal alignment. A long axis of liquid crystal molecules in the second portion aligns along a second direction perpendicular to the first direction.
