Abstract:
1. A color correcting polarizer comprising: a polarizer layer; and at least one discotic film layer, wherein the polarizer layer is an O-type polarizer, and the discotic film layer is optically transparent within the range of visible wavelength, and works as a polarizer in the wavelength range at least from 380 to 500 nm, wherein the discotic film layer is formed from a lyotropic liquid crystal based on discotic dichroic dye molecules, and the discotic film layer is made of the sulfonic derivatives of phenanthro-9′, 10′:2,3 quinoxaline of the general structural formula where n=1-4, m=1-4, and z=0-6 so that m+z+n≦12; X and Y=CH
