摘要： In a liquid crystal display device of a lateral electric field driving system, coloring problem in display is prevented in all the white, intermediate tone and the black display mode. In this liquid crystal display device: one of an incident side polarizing plate (5) and an exit side polarizing plate (9) has its polarizing axis substantially coincide with the direction of the orientation of a liquid crystal layer (10); an optical compensating layer (8) is interposed between at least one of transparent substrates (1,6) and the incident side polarizing plate (5) or the exit side polarizing plate (9) both disposed outside the at least one of the transparent substrates (1,6), the optical compensating layer (8) having a refractive index anisotropy with the other polarity other than that in the refractive index of the liquid crystal layer (10); and, the optical compensating layer (8) has the direction of its anisotropy axis substantially coincide with the direction of the orientation of the liquid crystal layer (10), provided that the orientation direction includes a predetermined pre-tilt angle.
