发明名称 METHOD FOR MANUFACTURING POLARIZING PLATE
摘要 Disclosed is a method for manufacturing a polarizing plate including both a film having a high laser-beam absorption rate and a film having a low laser-beam absorption rate, in which a strip-shaped polarizing plate is cut, leaving only a peeling film layer formed on the surface to be bonded to a substrate. The method for manufacturing the polarizing plate comprises: cutting from the upper surface of a surface protection film layer down to a layer immediately above a layer formed of the film having a low laser-beam absorption rate by using a laser; and subsequently cutting the layer formed of the film having a low laser-beam absorption rate and an adhesive layer by using a cutter. According to the method for manufacturing the polarizing plate, a delamination does not occur between a polarizer protection film layer and a surface protection film layer both constituting the polarizing plate and a contamination due to the adhesive running off from the cutting surface does not also occur, so that it is possible to obtain a polarizing plate excellent in close-bonding property with respect to a substrate.
