Abstract
According to one embodiment, a liquid crystal optical element includes a transparent substrate including a main surface, an alignment film disposed on the main surface, and a liquid crystal layer overlapping the alignment film and including a cholesteric liquid crystal including liquid crystal molecules stacked helically and an additive exhibiting a liquid crystalline property. In the liquid crystal layer, a reflective surface along which alignment directions of the liquid crystal molecules are identical is inclined with respect to the main surface.
