Abstract
A liquid crystal display apparatus of the present invention includes: a liquid crystal display device, the liquid crystal display device including: a pair of light transmissive substrates; a transparent electrode layer and an alignment film which are provided on one surface of each of the light transmissive substrates, the surface facing the other one of the light transmissive substrates; and a liquid crystal layer interposed between the pair of light transmissive substrates, wherein: the liquid crystal layer includes liquid crystal molecules; the liquid crystal molecules on a surface on each of the alignment films are pre-tilted in the same direction and by the same angle as those on a surface of the other one of the alignment films; and the liquid crystal layer has a homogeneous orientation; a pair of polarizers provided on respective sides of the liquid crystal display device; and at least one inclined phase plate including an index ellipsoid having three principal refractive indices na, nb and nc, wherein: the three principal refractive indices na, nb and nc of the index ellipsoid satisfy a relationship of na=nb>nc; each of the principal refractive indices na and nb is a princi…
