发明名称 DIFFERENT PHASE FILM
摘要 PROBLEM TO BE SOLVED: To greatly improve a display contrast and the visual field angle characteristic on tone inversion by the constitution in which three main refractive indices have biaxial alignability satisfying specific relations and the materials having refractive index anisotropy of specific angles have inclined alignment of specific angles, etc. SOLUTION: The different phase film A15 and 16 have the biaxial alignability that the three main refractive indices nx, ny, nz satisfy the relation nx<ny<fiz. In addition, the material having the refractive index anisotropy of 20 to 70 deg. in the angle formed by the optical axis of an X-axis is obliquely aligned in such a manner that the angle formed by a Z-axis and a film normal direction attains 20 to 70 deg. with a Y-axis as an axis of inclination. The angle formed by the optical axis of the films with the film face is 20 to 70 deg.. A polarizing plate 11/phase difference film B13/phase difference film A15/phase difference film C17/liquid crystal cell 10/phase difference film C18/phase difference film A16/phase difference film B14/polarizing plate 12 are laminated in this order between both polarizing plates 11, 12 and the liquid crystal cell 19.
