<P>PROBLEM TO BE SOLVED: To provide a polarizing plate having a wide viewing angle and reducing color shift upon black display, to provide a liquid crystal display device using the polarizing plate, having a wide viewing angle and reducing color shift upon black display, to provide the polarizing plate having above mentioned performance and to provide an image display device. <P>SOLUTION: In the polarizing plate comprising at least one protective film and a polarizing film, the protective film disposed on a liquid crystal cell side has Re(λ) and Rth(λ) satisfying the conditions of 45 nm≤Re(590)≤65 nm and 150 nm≤Rth(590)≤240 nm and a hue a* and a hue b* of the polarizing plate disposed in an orthogonal position satisfy the formulae 1.0≤a*≤2.0 and 1.0≤b*≤2.0 (wherein Re (λ) represents a retardation value (unit: nm) in plane at a wavelength of λ nm, and Rth (λ) represents a retardation value (unit: nm) along a thickness of the film). <P>COPYRIGHT: (C)2007,JPO&INPIT |
