Abstract: A polarizing sheet comprises a polarizing film interposed between a pair of protective films. The protective film comprises a cellulose ester of a lower fatty acid. The protective film has such heat moisture resistance that shrinkage ratio of the film in area is less than 10% after the film is left at 85.degree. C. and 90% RH for 500 hours. Further, the protective film has an equilibrium moisture content of less than 2.5 wt. % at 25.degree. C. and 65% RH. A liquid crystal display having the polarizing sheet is also disclosed.

Abstract: A method and an apparatus for thin film formation using off-set printing techniques, wherein a film-forming material is coated uniformly on a platform, which material is then transferred onto an object on which a thin film is to be formed. Coating the material on the platform is carried out by moving on the platform a roll coater which includes a distributing roller and a coating roller and which feeds the film-forming material onto the platform and by rotating the coating roller in a direction at which slippage in engagement between the coating roller and the platform is always involved in relation with the movement of the roll coater.
