Claim:
An optical compensation layer-attached polarizing plate, comprising a polarizing plate, an optical compensation layer ( 1 ) and another optical compensation layer ( 2 ) that are laminated in this order, wherein the optical compensation layer ( 1 ) has the relation nx 1 >ny 1 =nz 1 , comprises a resin with a photoelastic coefficient absolute value of at most 2.0×10 −11 m 2 /N, and has an in-plane retardation (nx 1 −ny 1 )d 1 in the range of 200 nm to 300 nm, where nx 1 is a refractive index in the direction of X axis along which the film in-plane refractive index is maximum, ny 1 is a refractive index in the direction of Y axis perpendicular to X axis, nz 1 is a refractive index in the direction of Z axis that is the film thickness direction, and d 1 is the film thickness (nm), the another optical compensation layer ( 2 ) has the relation nx 2 >ny 2 >nz 2 , comprises a resin with a photoelastic coefficient absolute value of at most 2.0×10 −11 m 2 /N, and has an in-plane retardation (nx 2 −ny 2 )d 2 in the range of 90 nm to 160 nm, where nx 2 is a refractive index in the direction of X axis along which the film in-plane refractive index is maximum, ny 2 is a refractive index in the direction of Y axis perpendicular to X axis, nz 2 is a refractive index in the direction of Z axis that is the film thickness direction, and d 2 is the film thickness (nm), a slow axis of the optical compensation layer ( 1 ) makes an angle of 10° to 30° with an absorption axis of the polarizing plate, and a slow axis of the another optical compensation layer ( 2 ) makes an angle of 75° to 95° with the absorption axis of the polarizing plate.
