Abstract

The present invention provides an ultra thin polarizing plate comprising a polarizer, a protective film formed on one surface of the polarizer, and an adhesive layer formed on the other surface of the polarizer, wherein the protective film has a resisting force of 2.1 to 18.7 N, and a liquid crystal display device having the ultra thin polarizing plate. The ultra thin polarizing plate according to the present invention can inhibit curl occurrence to prevent bonding defects by the curl in the process that the polarizing plate is bonded to a liquid crystal cell, and can make the thickness of the protective film thin, and therefore it can be effectively used in a flexible display.
