<P>PROBLEM TO BE SOLVED: To provide an inclined retardation film having high uniformity, and a liquid crystal display device which is superior in a view angle and color shift characteristics. <P>SOLUTION: In the inclined retardation film, wavelength dispersion L40 observed from the direction with 40° inclination from a normal direction of a film surface is 0.9 or more and 1.09 or less, an average inclination angle β1 is 50°or more and 85°or less, refractive index ellipsoid in-plane retardation Ro' satisfies 0≥Ro'≥80 nm, and refractive index ellipsoid thickness retardation Rth' satisfies -200≥Rth'≥-30 nm. <P>COPYRIGHT: (C)2012,JPO&INPIT |
