<P>PROBLEM TO BE SOLVED: To provide an optical compensation film which contributes to achievement of wider viewing angle of a polarizing plate, and to provide a polarizing plate and a liquid crystal display each exhibiting a wide viewing angle characteristic. <P>SOLUTION: The optical compensation film includes a light absorbing layer and a retardation layer, wherein the light absorbing layer shows absorption anisotropy in the plane (x-y plane) thereof with respect to light of wavelength λ nm in the visible light region, absorption coefficients kx(λ) and ky(λ) in the plane (therein, ky<kx) and thickness d (nm) of the light absorbing layer satisfies the following relation and in-plane absorption axis of the light absorbing layer and in-plane slow axis of the retardation layer are orthogonal to each other; 22 nm<(kx(λ)-ky(λ))×d<430 nm. The polarizing plate having the optical compensation film and liquid crystal display having the polarizing plate are also provided. <P>COPYRIGHT: (C)2010,JPO&INPIT |
