Abstract
A composition for protective layers of a polarizing plate includes a photocurable monomer or oligomer having a glass transition temperature (Tg) of about 50° C. or greater, particles, a reactive monomer or oligomer, and an initiator. A polarizing plate includes a polarizer and a protective layer formed from the composition on one or both surfaces of the polarizer. The protective layer has a storage modulus at about 25° C. of greater than about 2000 MPa, as measured at a heating rate of 10° C./min, a temperature of −50° C. to 100° C., a frequency of 1 Hz, and a strain of 0.5%. An optical display includes the polarizing plate.
