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.

Abstract: An alignment coating method for a substrate includes providing at least one substrate and at least one alignment plate, covering the alignment plate on to the substrate, coating polyimide liquid on the alignment plate, and transferring a polyimide liquid on the alignment plate to a region out of a blind via on the substrate according to a preset printing direction through a printing mechanism. Each of the substrates has the blind via. The alignment plate has at least one opening. The opening corresponds to the blind via.
