Abstract
A polarizing plate protective film containing a compound represented by formula (I); a polarizing plate; and a display: in formula (I), X represents a group of formula (I-A-1) or (I-A-2), L represents a single bond or a divalent linking group, Z represents an n-valent linking group, and n represents an integer of 2 or more; however, when n is 2, the case where L and Z each are simultaneously a single bond is excluded: in formulae (I-A-1) and (I-A-2), RAC1 and RAC2 each independently represent an alkyl, cycloalkyl, aryl, or acyl group; however, the case where RAC1 and RAC2 bond to each other to form a ring is excluded; RAC3 to RAC6 each independently represent a hydrogen atom, or an alkyl, cycloalkyl, aryl, acyl, alkoxy, or alkoxycarbonyl group; and an asterisk (*) represents a bonding hand to form a bonding with L.
