  • Patent number: 6124907
    Abstract: A liquid crystal display includes at least one polarizer located interior or internally of substrates of the display. In certain embodiments, the polarizer may be spin-coated onto the interior of one of the substrates, preferably the passive substrate of the display. Such a polarizer may also be located interior of color filters on the copassive substrate. Thus, light being transmitted through the display proceeds through the front polarizer prior to being de-polarized by the color filters. The result is improved contrast ratios in the display due to the minimization of the de-polarizing of color filters. In certain embodiments, the internal polarizer(s) may be photo-patternable by way of ultraviolet photo-imaging.
