ABSTRACT:
As a polarizing plate with optical compensation function, that is thin and excellent in optical characteristics, the present invention provides a polarizing plate with optical compensation function including at least two optically compensating layers. The optically compensating layers includes: an optically compensating A-layer formed of a polymer film, satisfying conditions represented by formulae (I) and (II) below; and an optically compensating B-layer formed of a non-liquid crystalline polymer film, satisfying conditions represented by formulae (III) to (V) below.in-line-formulae description="In-line Formulae" end="lead"?20 (nm)≦Rea≦300 (nm)  (I)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1.0≦Rza/Rea≦8  (II)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1 (nm)≦Reb≦100 (nm)  (III)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?5≦Rzb/Reb≦100  (IV)in-line-formulae description="In-line Formulae" end="tail"?in-line-formulae description="In-line Formulae" end="lead"?1 (μm)≦db≦20 (μm)  (V)in-line-formulae description="In-line Formulae" end="tail"?The present invention also provides a liquid crystal display using the polarizing plate.
