An optically compensatory film in which a birefringent phase retarder layer is adhesively supported by a transparent film base is provided. The transparent film base has a specific gravity of not larger than 1.15 or a water absorption coefficient of not higher than 1.0% (at 23° C. and for 24 hours), and has an photoelastic coefficient of not larger than 30×10−12 m2/N. An optically compensatory polarizing plate is constituted of a laminate of the optically compensatory film and a polarizing plate, the optically compensatory film including a phase retarder layer composed of a liquid-crystal polymer.

A polarizing plate with an optical compensation layer is provided, which has an excellent peelability and is easy to reattach after mounted on an image display apparatus. A pressure-sensitive adhesive layer satisfying the condition (I) below is formed on both surfaces of an optical compensation layer, and one of the pressure-sensitive adhesive layers is further laminated with a polarizing plate.condition (I): in the case where a pressure-sensitive adhesive layer causing the optical compensation layer and the polarizing plate to adhere to each other is expressed by a pressure-sensitive adhesive layer (A) and the other pressure-sensitive adhesive layer is expressed by a pressure-sensitive adhesive layer (B) and attached to a glass substrate, the pressure-sensitive adhesive layer (A) causing the optical compensation layer and the polarizing plate to adhere to each other has an adhesive strength exceeding 12 N/25 mm, and the pressure-sensitive adhesive layer (B) causing the optical compensation layer and the glass substrate to adhere to each other has an adhesive strength of 1 to 10 N/25 mm.
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.
