<p>A method of manufacturing a polarizing plate in which an original polarizing plate is cut accurately, cracks are not extended easily in a section and foreign substances are not attached easily on a polarizing plate to be obtained, and a cutting mat to be used in the method are provided. An original polarizing plate having a plurality of layers is fixed on a first principal surface of an ultrahigh molecular weight polyethylene porous sheet (1) by drawing from the opposite side. The original polarizing plate (2) is cut by a blade (4) moving across the thickness of the original polarizing plate by using the porous sheet (1) as a cutting mat to obtain a polarizing plate (3) having a plurality of layers. A curable liquid, such as ultraviolet curable ink, is impregnated in vacant pores of the porous sheet (1), and is cured to obtain a sheet. The sheet thus obtained is particularly suitable for a cutting mat.</p> |
