Original Abstract Submitted
According to one embodiment, a liquid crystal optical element includes an optical waveguide including a first main surface and a second main surface opposed to the first main surface, an alignment film disposed on the second main surface, a liquid crystal layer which overlaps the alignment film, which includes cholesteric liquid crystals, and which reflects at least part of light incident through the optical waveguide toward the optical waveguide, and a transparent first cover member opposed to the liquid crystal layer with a first low-refractive-index layer interposed between the first cover member and the liquid crystal layer, the first low-refractive-index layer having a refractive index lower than a refractive index of the liquid crystal layer.
