Abstract:
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.

Abstract:
It is an object of the present invention to provide a display strip with which the step of attaching a product-enclosed bag is easily automated and a product-enclosed bag is easily bonded again after the bag is once detached. The present invention relates to a display strip for arranging and attaching a plurality of product-enclosed bags for the display, which comprises at least a substrate layer and a sealant layer, the sealant layer being bondable to a surface layer of the bag by thermocompression bonding and having no pressure sensitive adhesive property before the thermocompression bonding, but being bondable to the bag again owing to exposure of a pressure sensitive adhesive face in the case of peeling of the bag bonded by thermocompression bonding.
