摘要： A liquid crystal cell substrate having a polarizing function is disclosed which can be extremely thin and lightweight and is excellent in heat resistance, impact resistance and quality stability. The liquid crystal cell substrate comprises a resin substrate and, closely adhered thereon, at least a gas barrier layer, a crosslinked resin layer and a polarizing layer, wherein the polarizing layer comprises a coating layer. This cell substrate, having a polarizing function and high durability, can be efficiently produced because an exceedingly thin polarizing layer having excellent heat resistance can be deposited on a resin substrate by coating and because a gas barrier layer and a crosslinked resin layer also can be easily formed. It is excellent in moisture resistance, gas resistance and impact resistance, can be extremely thin and lightweight, and has excellent heat resistance. With this liquid crystal cell substrate, a liquid crystal cell excellent in the long-term stability of display quality can be fabricated.

摘要： An inclined optical compensation film formed from a non-liquid-crystal polymer, which is useful in a TN mode liquid crystal display. A substrate is coated with a non-liquid-crystal polymer to thereby form a coating film; the non-liquid-crystal polymer of the coating film is inclined and aligned; and the coating film is solidified, thereby forming an inclined optical compensation film. The non-liquid-crystal polymer can be inclined and aligned by, for example, applying external force, such as wind blowing, to the coating film. This inclined optical compensation film exhibits, for example, a birefringence (Δn) ranging from 0.001 to 0.5 and thus is useful in a TN mode liquid crystal display, etc.

摘要： The present invention provides a laminated retardation plate that shows an excellent viewing angle property when used in a liquid crystal display, and that can be decreased in thickness. The laminated retardation plate is formed by laminating an optically anisotropic layer (A) made of a polymer having an in-plane retardation of 20-300 nm and a ratio between a thickness direction retardation and the in-plane retardation of not less than 1.0, and an optically anisotropic layer (B) made of a non-liquid crystalline polymer such as polyimide having an in-plane retardation of not less than 3 nm and a ratio between a thickness direction retardation and the in-plane retardation of not less than 1.0. The thus obtained laminated retardation plate shows excellent optical properties, e.g., an in-plane retardation (Re) of 10 nm or more, and a difference between a thickness direction retardation and the in-plane retardation of 50 nm or more.
