A liquid crystal display has a liquid crystal layer that is sandwiched between a pair of electrode substrates in a manner so as to contact alignment films, and also has a liquid crystal display element having optical phase-difference plates placed on both sides thereof. The liquid crystal layer is divided into a first division-section and a second division-section that have different sizes and that are oriented by the alignment films in respectively different directions. Further, with respect to the first division-section that has the larger size, an optical phase difference plate is placed so that the index ellipsoid, which identifies the refractive-index anisotropy of the optical phase-difference plate, has an inclined direction to the optical phase-difference plate that is opposite to the pretilt direction of liquid crystal molecules located in the vicinity of the alignment films. Thus, since biased optical characteristics are properly compensated, viewing-angle characteristics in the case of inclined viewing angles can be improved. Consequently, it becomes possible to eliminate the occurrences of a gradation-inverting phenomenon in the up and down directions as well as right and left directions and a coloring phenomenon in the up and down direction, and consequently to improve contrast while eliminating display unevenness.
