Abstract: An organically modified sol-gel method of preparing substantially crack-free aluminosilicates films is provided. Chelated aluminum alkoxide and polydimethylsiloxane are mixed in a 1:1 ratio by weight in a solvent and refluxed at approximately the boiling temperature of the solvent to produce a sol-gel liquid including polymerized aluminosilicates. The sol-gel liquid is cooled to room temperature. Additional solvent is added to the sol-gel liquid to reduce its viscosity. A substrate is coated with the reduced viscosity sol-gel liquid. The coating of sol-gel liquid on the substrate is dried to produce an organically modified aluminosilicates sol-gel film. The sol-gel film is heated, to enhance polymerization of the sol-gel film and to evaporate residual solvent, and then cooled.

Abstract: A liquid crystal display is provided which has improved wide angle viewing characteristics. The liquid crystal display includes a liquid crystal matrix. A non-planar fluorescent lamp positioned on a first side of the liquid crystal matrix has a center which traverses the fluorescent lamp in at least one longitudinal direction. A distance between the first side of the liquid crystal matrix and the fluorescent lamp center in a first portion of the fluorescent lamp is less than a distance between the first side of the liquid crystal matrix and the fluorescent lamp center in a second portion of the fluorescent lamp.
