摘要： The present invention relates to a light shield for use in liquid crystal displays. According to the present invention, the light shielding layer includes an acrylic resin with a cross-linked structure in which carbon black particles are dispersed. Further, the light shield may be adapted to cover a switching element which controls the voltage applied to the liquid crystals. In addition, the present invention is directed to a method of manufacturing a light shield which includes an acrylic resin with cross-linked structure in which carbon black particles are dispersed.

摘要： 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.

摘要： Color filters, including those used in a liquid crystal display, aee repaired in a self-aligning manner. Defective parts of the colored pixels of a filter are filled with a negative type photosensitive resin containing a pigment of the same color as the colored pixel. The photosensitive resin is exposed to light through the defective colored pixels and the exposed resin is developed. When the defect extends through pixels of different colors, a gray colored resin is utilized. The gray colored resin has a color temperature equal to that of the white color temperature resulting from the additive color process of the colors of the various colored pixels of the filter.
