Optical member, cell substrate and liquid-crystal display |
摘要 |
An optical member is made from an optical material either one of or each of two surfaces of which is coated with a pressure sensitive adhesion layer having a 1000% elastic modulus in a range of from 3 g/mm2 to 10 g/mm2 at 90° C. The optical member exhibits characteristic in which the quantity of curl is not larger than 3 mm per 12 inches when the optical member adhesively bonded to a resin substrate through the pressure sensitive adhesion layer is heated at 80° C. for 150 hours. A cell substrate comprises a resin substrate having a curl quantity of not larger than 3 mm per 12 inches when an optical member is heated at 80° C. for 150 hours after the optical member is adhesively bonded to the resin substrate through the pressure sensitive adhesion layer. A liquid-crystal display wherein an optical member is adhesively bonded, through a pressure sensitive adhesion layer of the optical member, to either one of or each of two surfaces of a liquid-crystal cell is formed by use of the cell substrate.
