Patent ID: 6882475

Claim:
A polarizing member comprising a sheet-like member formed so that linearly polarized light can be obtained as transmitted light through said sheet-like member after natural light is incident on a rear surface of said sheet-like member, wherein said sheet-like member exhibits a transmittance difference of not larger than 6% between transmitted light components within a 20 nm-wide wavelength region in a transmission spectrum of light in a wavelength range of from 520 to 640 nm when said natural light is incident on said sheet-like member at any angle ranging from an angle viewing from a line normal to a surface of said sheet-like member to an election angle of 80 degrees with respect to the line normal to the surface of said sheet-like member, said sheet-like member comprising a laminate of an absorptive type polarizer, a circularly polarized light separating sheet comprising cholesteric liquid-crystal layers in close and integral contact with one another, and a quarter wave plate.
