A liquid crystal (LC) medium for polymerization alignment process includes at least a set of LC molecules, at least a set of reactive monomers, and at least one inhibitor at a concentration in a range of 0.01-1% wt of the reactive monomer. The inhibitor quenches polymerization of radicals of the reactive monomers, which is triggered by light or heat before the polymerization alignment process. Therefore influence on the reactive monomers before the polymerization alignment process is reduced and stability of the LC medium is improved.
