OPTICAL FILM, POLARIZING PLATE, AND LIQUID CRYSTAL DISPLAY

摘要

An optical film characterized by satisfying both the relationship (A): 0 = |?s - ?c| = 0.3 [wherein ?c is an orientation angle as determined at the transverse-direction center (L), and ?s is an orientation angle in a region (M) which spreads at least 900mm apart from the transverse-direction center (L) in the transverse direction], and the relationship (B): 0 = |Re(s) - Re(c)| = 2.0 [wherein Re(c) is an in-plane retardation as determined at the transverse-direction center (L), and Re(s) is an in-plane retardation in a region (M) which spreads at least 900mm apart from the transverse-direction center (L) in the transverse direction]; a polarizing plate provided with the optical film; and a liquid crystal display provided with the polarizing plate.
