Polarizing sheet and liquid crystal display

摘要

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 DEG C. and 90% RH for 500 hours. Further, the protective film has an equilibrium moisture content of less than 2.5 wt. % at 25 DEG C. and 65% RH. A liquid crystal display having the polarizing sheet is also disclosed.
