Abstract
Provided are a polarizing plate including a polarizer and a polarizing plate protective film laminated on the polarizer, in which the polarizing plate protective film contains at least one compound represented by any one of General Formulas (1) to (3) and cellulose acylate; an image display device using the polarizing plate; and a polarizing plate protective film used for the polarizing plate, and R7—N═C═N—R8 General Formula (3) in which R1 to R8 represent a specific substituent.
Claims10
A polarizing plate comprising:
- a polarizer;
- and
- a polarizing plate protective film laminated on the polarizer,
- wherein the polarizing plate protective film contains at least one compound represented by any one of General Formulas (1) to (3), and cellulose acylate,
- in General Formula (1), R1 and R2 represent an alkyl group, a cycloalkyl group, an aryl group, an acyl group, an alkoxy group, an aryl carbonyl group, or a carbamoyl group, and R3 represents an alkyl group, a cycloalkyl group, or an aryl group,
- in General Formula (2), R4 and R5 represent an alkyl group, a cycloalkyl group, an aryl group, an acyl group, an alkoxy group, an aryl carbonyl group, or a carbamoyl group, and R6 represents an alkyl group, a cycloalkyl group, or an aryl group, and
- R7—N═C═N—R8 General Formula (3)
- in General Formula (3), R7 and R8 represent an alkyl group, a cycloalkyl group, or an aryl group,
- provided that in each of General Formulas (1) to (3), a carbon atom and a nitrogen atom which are shown to be linked to each other by a double bond are not ring-constituting atoms of a monocyclic ring.
