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; ¦ -N-X wherein X is a hydrogen atom or substituted or unsubstituted phenyl radical, and at least one atomic group of the formula: ¦ -C=Y, 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 of A. MIXTURES OF A QUINONE COMPOUND AND A COMPOUND IN WHICH OXO GROUPS OF THE QUINONE COMPOUND ARE SUBSTITUTED BY HYDROXYL GROUPS.
