ABSTRACT:
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)×d  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}×d.  Formula (II)in-line-formulae description="In-line Formulae" end="tail"?
