Abstract
In a liquid crystal display apparatus in which a first substrate and a second substrate are disposed in parallel to each other through a liquid crystal layer, a liquid crystal molecule in the liquid crystal layer is rotated in a plane parallel to the first substrate and the second substrate by driving voltage applied to the liquid crystal layer. A voltage value corresponding to a maximum gradation value of the driving voltage applied to the liquid crystal layer is a driving voltage value at which transmittance peaks based on V-T characteristics in an inclination direction inclined from a normal direction of a display surface of the liquid crystal display apparatus to a direction in which a refractive index of the liquid crystal layer is maximum.
