PURPOSE: To realize mass-production and stabilized quality by removing unnecessary parts of a large-sized polarizing plate stuck on a large-sized liquid-crystal cell except parts corresponding to individual liquid-crystal cells from the large- sized liquid-crystal cell together with film sheets provided to the large-sized polarizing plate.

CONSTITUTION: A film sheet 3 for peeling is stuck on the surface of the large- sized polarizing plate 2 and a film sheet 4 for protection is stuck on the reverse surface. Then, cutting lines 5 are drawn on the film sheet 3 for peeling and large-sized polarizing plate 2 in conformity with the shape of individual polarizing plates as many as liquid-crystal cells, and square cut parts 6 of the film sheet 3 for peeling are peeled off. Then, large-sized polarizing plate 2 is stuck on both top and reverse surfaces of the large-sized liquid-crystal cell 1 at the side of the film sheet 3 for peeling. Then, the film sheet 3 for peeling, large-sized polarizing plate 2, and film sheet 4 for protection are peeled off together. Consequently, only necessary polarizing plates 2a... are stuck on both top and reverse surfaces of the large-sized liquid-crystal cell 1.
