  A polarizing plate composition, a polarizing plate protective film, a polarizer, a polarizing plate, and a liquid crystal display device contain a compound represented by the following Formula (I). In Formula (I), R represents a specific substituent, and each of EWG1 and EWG2 represents an electron-withdrawing group. EWG1 and EWG2 may form a ring by being bonded to each other. Here, there is no such case where EWG1 and EWG2 become the following group by being bonded to each other and form a ring by being bonded to a carbon atom substituted with R. Each of Rx and Ry represents a hydrogen atom or a substituent. * represents a position of bonding to a carbon atom substituted with R.
