Abstract:
A light-polarizing film processing a dichroic dye and having a light transmittance of not more than 0.3% at wavelengths of from 430 nm to 500 nm inclusive when irradiated with a linearly polarized light with a vibration plane parallel to an absorption axis of said film, and a light transmittance of not less than 77% at wavelengths of from 430 nm to 500 nm nm inclusive when irradiated with a linearly polarized light with a vibration plane perpendicular to the absorption axis of said film, wherein the dichroic dye comprises any one of the combinations of: C.I. Direct Orange 39 and C.I. Direct Red 81; C.I. Direct Orange 39 and C.I. Direct Red 2; C.I. Direct Orange 39 and C.I. Direct Red 28; C.I. Direct Orange 107 and C.I. Direct Red 81; C.I. Direct Orange 107 and C.I. Direct Red 2; and C.I. Direct Orange 107 and C.I. Direct Red 28.
