To obtain a liquid crystal display device capable of performing excellent display even when a foreign matter exists on a polarizing plate, and the polarizing plate.
The machining method for the polarizing plate is a method for machining the polarizing plate 100 having a polarizing layer 111 inside, and includes a small-diameter hole part forming process for forming a hole part 130 on the polarizing plate 100 by laser beam machining on a faulty display area where the foreign matter 200 exists, a large-diameter hole part forming process for forming a large-diameter hole part 140 having a larger diameter than the hole part 130 formed in the small-diameter hole part forming process by removing a part which does not reach the layer 111 by the laser beam machining, and a light shielding forming process for embedding a light shielding member 150 in the hole parts formed in the respective processes.
