摘要：
A polarizing plate excellent in polarization performance in all wavebands from a short wavelength region to a long wavelength region and a liquid crystal display using such a polarizing plate. The polarizing plate including a polarizer has a portion having a polarization degree of 99% or more at each wavelength of light for wavelengths of 420 to 550 nm and a portion having a polarization degree of 99% or more at each wavelength of light for wavelengths of 550 to 700 nm.
