Abstract
Provided are a liquid crystal member and a millimeter-wave modulation element with the liquid crystal member including a liquid crystal layer having a non-flat surface. The liquid crystal member includes a liquid crystal layer in which a liquid crystal composition which contains a liquid crystal compound having a polymerizable group and a polymerization initiator is immobilized in an aligned state, with at least one main surface of two main surfaces of the liquid crystal layer at both ends in a thickness direction is a non-flat surface having various shapes in a region on the non-flat surface side of one of the two main surfaces, a slow axis of the liquid crystal compound has an equal angle with respect to an adjacent non-flat surface, and in a region on the other main surface side, slow axes of the liquid crystal compound are parallel to each other.
