Abstract
According to one embodiment, a liquid crystal optical element includes a substrate, an alignment film, and a liquid crystal layer. The alignment film includes a plurality of first areas and a second area. The liquid crystal layer includes a first alignment area overlapping with the first area and including a plurality of first liquid crystal molecules forming an alignment pattern in which longitudinal axes of the first liquid crystal molecules successively vary and a second alignment area overlapping with the second area and including a plurality of second liquid crystal molecules, longitudinal axes of the plurality of second liquid crystal molecules being arranged in the same direction.
