    • A liquid crystal composition having a homogeneous alignment of the liquid crystalline molecules, comprises a liquid crystal material, for example, nematic, smectic and cholesteric liquid crystal substances, an additive effective for forming the homogeneous alignment, said additive consisting of at least one heterocyclic compound having a five or six-membered heterocyclic ring containing therein at least one atomic group selected from the class consisting of the atomic group of the formulae; ##EQU1## wherein X is a hydrogen atom or substituted or unsubstituted phenyl radical, and at least one atomic group of the formula: ##EQU2## Y, wherein Y represents an oxygen or sulfur atom, said heterocyclic compounds being different from indigo, and, if necessary, a supplementary additive effective for enhancing the dynamic scattering property of the liquid crystal material, said supplementary additive consisting of at least one substance selected from the class consisting ofA. mixtures of a quinone compound and a compound in which oxo groups of the quinone compound are substituted by hydroxyl groups.B. organic cyclic compounds having either a hydroxyl or amino group, or both, and either a carbonyl or imino group, or both, andC. mixtures of one or more of the organic cyclic compounds as defined in the above Item (b) and at least one compound selected from the group consisting of the quinone and substituted quinone compounds as defined in the above Item (a).
