Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an optical film and an optical sheet excellent in sustention of polarizance in a polarizing plate for a liquid crystal display device using iodine as a pigment. SOLUTION: The optical film or optical sheet is a protective film or protective sheet for a polarizing plate formed from a resin containing a triazine compound represented by general formula (1), wherein R1represents a 1-12C linear or branched alkyl group, a 3-8C cycloalkyl group or alkenyl group, a 6-18C aryl group, a 7-18C alkylaryl group or arylalkyl group, and R2represents a 1-8C alkyl group or a 3-8C alkenyl group.
