Abstract
A protective film for a polarizing plate includes a base film and a primer layer on one or both sides of the base film. The protective film has a transmittance of about 90% or greater at a wavelength of 550 nm, and a ratio of the refractive index (B) of the primer layer to the refractive index (A) of the base film of about 0.6 to about 1.0. The protective film exhibits good adhesiveness to the polarizer and improves the transmittance of the polarizing plate. A polarizing plate including the same, and a liquid crystal display including the same are also disclosed.
