Abstract:
In a liquid crystal display apparatus in which a liquid crystal layer is twist-aligned when no electric field is applied, Δnd value of a liquid crystal layer in a wavelength of 550 nm is 300 to 400 nm, each of directions of polarizing axes of pair of linear polarizers is substantially parallel or vertical to the alignment direction of liquid crystal molecules in each end face of the liquid crystal layer that is closer to each of linear polarizers, and the angle between polarizing axes of the pair of linear polarizers is 85° or larger and smaller than 90°. In a liquid crystal display apparatus in which a liquid crystal layer is aligned to be substantially vertical when no electric field is applied, the angle between polarizing axes of the pair of linear polarizers is 85° or larger and smaller than 90°. In a liquid crystal display apparatus of a lateral electric field drive system, a uniaxial alignment angle of a liquid crystal layer when no electric field is applied is larger than −45° and −40° or smaller, or +40° or larger and smaller than +45°.
