Abstract
A color-correcting polarizer is provided comprising a polarizer layer and at least one discotic film layer. The discotic film layer is optically transparent within the range of visible wavelength. The discotic film layer works as a polarizer in the wavelength ranges at least from 380 to 500 nm and/or from 600 to 780 nm. A liquid crystal cell comprising the color correcting polarizer is also disclosed.
