Abstract
In a liquid crystal display element of the present invention, the aligning capability for imparting pre-tilt angles to a liquid crystal material is imparted only to the surface of the alignment film of one of the substrates, the material layer having dielectric anisotropy includes a chiral material and a liquid crystal material with a nematic liquid crystal phase, 0.25≦d/p≦0.50 is satisfied assuming that the thickness of the material layer having the dielectric anisotropy is d and the chiral pitch length of the liquid crystal material is p, and 1000×d/p≦Δn×d is satisfied assuming that the refractive index anisotropy of the liquid crystal material is Δn.
