Patent ID: 7781068

Claim:
An observation side polarizing plate comprising: a polarizing film; and a pair of polarizing-plate-protecting films laminated on an observation side of the polarizing film and on an opposite side of the polarizing film, respectively, through water-based adhesive layers; wherein the polarizing-plate-protecting film on the observation side of the polarizing film comprises a polyester film comprising a biaxially oriented polyethylene terephthalate film having a thickness of 25-300 μm, and an adhesion-facilitating layer containing a hydrophilic acetyl cellulose resin and a thermosetting polyester resin, formed on the polarizing film side of the polyester film, wherein a content of the hydrophilic acetyl cellulose resin is more than 50% by weight of a total resin content of the adhesion-facilitating layer.
