<P>PROBLEM TO BE SOLVED: To produce a polarizing plate protective film which exhibits excellent visibility. <P>SOLUTION: The polarizing plate protective film is produced by filtering a cellulose ester solution of which the viscosity is in a range of 50-500 P with a filter medium having an absolute filtration accuracy of ≤0.005 mm, flow-casting the filtered solution on a support, peeling a flow-cast film from the support, and drying it. <P>COPYRIGHT: (C)2008,JPO&INPIT |
