POLARIZING PLATE WITH OPTICAL COMPENSATION LAYER, LIQUID CRYSTAL PANEL USING POLARIZING PLATE WITH OPTICAL COMPENSATION LAYER, LIQUID CRYSTAL DISPLAY UNIT, AND IMAGE DISPLAY UNIT

摘要

A polarizing plate with an optical compensation layer capable of contributing to its thinning, realizing high contrast with viewing angle characteristics improved, preventing interference non-uniformity and thermal non-uniformity, being limited in color shift, delivering a good color reproducing feature, and favorably preventing light leakage at black displaying; and a liquid crystal panel, a liquid crystal display unit and an image display unit using such a polarizing plate with an optical compensation layer. The polarizing plate with an optical compensation layer comprises a polarizer, a first optical compensation layer, an adhesive layer, and a second optical compensation layer sequentially in the order mentioned, wherein the first optical compensation layer has a refractive index distribution, nx>ny=nz, with its in-plane phase difference Re₁ exhibiting wavelength dispersion characteristics that gradually decrease toward a short-wavelength side and with its in-plane phase difference Re₁ being 90-160 nm, and the second optical compensation layer is a coating layer, has a refractive index distribution, nx=ny>nz, with its in-phase difference Re₂ being 0-20 nm, its phase difference Rth₂ in thickness direction being 30-300 nm and its thickness being 0.5-10 µm.
