Abstract

According to one embodiment, a liquid crystal optical element includes a substrate, a first alignment control layer disposed on the substrate and comprising projections arranged at a predetermined pitch, and a first liquid crystal layer disposed on the first alignment control layer. The first liquid crystal layer comprises liquid crystal molecules which are aligned such that major axes of the liquid crystal molecules extend along the projections, respectively, and cured in a state where alignment directions of the liquid crystal molecules are fixed. The first alignment control layer is formed of a crosslinkable liquid crystal polymer.
