A liquid crystal composition that includes a polymerizable compound having a high solubility, a composition obtained by polymerizing the polymerizable compound in the liquid crystal composition, and an AM device including any of the compositions are described. The liquid crystal composition has negative dielectric anisotropy, and includes at least one compound selected from the group of compounds represented by formula (1): wherein P1 and P2 are polymerizable groups, and, for example, ring A and ring B are independently an adamantane ring or a noradamantane ring, Z1, Z2 and Z3 are a single bond, and a, b and c are 1.
