The present invention relates to a polarizing plate characterized in that pressures-sensitive adhesives used in the upper and lower polarizing plates have different elastic properties and a liquid crystal display device comprising the same. More specifically, the present invention relates to a polarizing plate with improved light leakage phenomenon in accordance with bend of liquid crystal panels, characterized in that as slid distances of pressure-sensitive adhesives on the polarizing plate having the pressure-sensitive adhesive layer formed thereon and bonded to a glass plate with a contact area of 1 cm×1 cm at the time of applying a load of 1,000 gf at room temperature (25° C.) for 1,000 seconds, the difference between the slid distance X1 of pressure-sensitive adhesive for the upper polarizing plate and the slid distance X2 of pressure-sensitive adhesive for the lower polarizing plate is 50 to 500 μm.
