Abstract: A polarizing plate and a liquid crystal display device are provided which can prevent abrasion since the roughness and coefficient of friction of an outer base material of a polarizing plate are designed depending on the surface hardness of the outer base material by conducting studies and tests that are conducted into factors causing abrasion between the polarizing plate and an optical sheet and taking the results into account. Therefore, the problem of abrasion between the polarizing plate and the optical sheet associated with slim-profile liquid-crystal display devices can be solved, thereby achieving a slim design without cost increase.
