    摘要: A protective film for polarizers which comprises a cellulose ester film and which, even when stored for long, suffers no film deformation failures such as ridging and protrusion failures; a process for producing the protective film; a polarizer; a process for producing the polarizer; and a liquid-crystal display employing the polarizer. The process for producing a protective film for polarizers is characterized by forming a melt comprising a cellulose ester and at least one member selected among compounds respectively represented by the following general formulae (1) to (3) into a continuous cellulose ester film by melt casting and winding the film into a roll. [Chemical formula 1] General formula (1) (In the formula, R1 to R5 each represents a substituent.) [Chemical formula 2] General formula (2) (In the formula, R1 to R6 each represents a substituent.) [Chemical formula 3] General formula (3) (In the formula, Rf represents perfluoroalkyl, Rc represents alkylene, Z represents a nonionic polar group, n is 0 or 1, and m is an integer of 1-3.)
