Abstract

A polarizing plate and a liquid crystal display device are provided. The polarizing plate includes a polarizing layer, a short wavelength band blue light film, a supporting layer, a release film, and a protective film. The short wavelength band blue light film is disposed on an upper side or a lower side of the polarizing layer. The supporting layer is disposed on a side of the polarizing layer opposite another side of the pluralizing layer facing the short wavelength band blue light film. The release film is disposed on a lower side of the polarizing layer. The release film is connected to the polarizing layer or the short wavelength band blue light film through an adhesive layer.
