Abstract: A polarizing plate includes a polarizer, a bonding layer on an upper surface of the polarizer, a protective film on an upper surface of the bonding layer and having a moisture transmittance of about 30 g/m2·24 hr or less at 40° C. and 90% relative humidity (RH), and a barrier layer on a lower surface of the polarizer and formed of a barrier layer composition including an alicyclic epoxy resin having a glass transition temperature of about 200° C. or more. The polarizing plate may have a light transmittance variation rate of 3% or less, as calculated by Equation 1: Light transmittance variation rate=|T0−T500|/T0×100  (1), where T0 is an initial light transmittance and T500 is a light transmittance after 500 hours as set forth herein.
