发明名称 Liquid crystal display
摘要 A liquid crystal display comprising: a brightness enhancing film, polarizing plate (A), a liquid crystal cell, polarizing plate (B) laminated in that order, Wherein (i) polarizing plate (A) has a polarizing plate protective film facing the brightness enhancing film; (ii) the polarizing plate protective film is a cellulose ester film; (iii) an in-plane retardation value Ro(550) of the of the cellulose ester film represented by Formula (I) is 0 to 5 nm; and (iv) a retardation value in a thickness direction Rt(550) of the of the cellulose ester film represented by Formula (II) is -15 to 15 nm, <?in-line-formulae description="In-line Formulae" end="lead"?>Ro(550)=(Nx-Ny)xd Formula (I) <?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>Rt(550)={(Nx+Ny)/2-Nz}xd. Formula (II) <?in-line-formulae description="In-line Formulae" end="tail"?>
