  • Patent number: 5374493
    Abstract: The present invention is a color filter and method of making a color filter in which a reactive dye is added to a photosensitive composite, which contains pigment to form the color filter, and the reactive dye reacts with the binder polymer of the photosensitive composite to form a color filter having a high contrast color filter. The photosensitive composite, which has a primary color and which contains the product of the binder polymer and the reactive dye, is deposited on a glass substrate over a shielding layer. A layer of PVA is then deposited on the photosensitive composite layer. A masking layer then defines the area of the specific primary color for the photosensitive composite. This process is then repeated for the remaining primary colors of the color filter. The color filter produced by this process has a very high contrast ratio.

  • Patent number: 5229039
    Abstract: The present invention relates in general to color liquid crystal displays and more particularly to color liquid crystal displays in which the color filter functions as the orientation layer. A film which functions as both an orientation layer controlling the orientation of liquid crystal molecules and as a color filter is described. A process for producing the combination film is also described. The process comprises synthesizing a polyimide precursor by the ring-opening polyaddition reaction of a diamine component and an acid anhydride component in a solvent. Wherein the diamine component has a predetermined structure. Further, the acid anhydride component has a predetermined structure. Finally, the process includes the step of dispersing coloring materials in the polyimide precursor to form the filter.
