ABSTRACT:
A liquid crystal display element of the present invention is arranged so that a material layer having dielectric anisotropy includes a chiral material and a liquid crystal material with a nematic liquid crystal phase, and 0.25≦d/p≦0.50 is satisfied assuming that the thickness of the material layer is d and the chiral pitch length of the liquid crystal material is p.
