Polarizing plate having pressure sensitive adhesive layer with improved light leakage property

A liquid crystal display device comprising:

• a liquid crystal panel that comprises an upper polarizing plate that is attached on one side of a liquid crystal cell by a pressure-sensitive adhesive layer for the upper polarizing plate and a lower polarizing plate that is attached on the other side of the liquid crystal cell by a pressure-sensitive adhesive layer for the lower polarizing plate, and
• a backlight unit which is disposed under the liquid crystal panel which transmits light through the lower polarizing plate that is observed through the upper polarizing plate,
• wherein the upper and lower polarizing plates are adhered with crossing their optical axes of 0 degree and 90 degree so that elongation axis directions of the upper and lower polarizing plates are asymmetrical, and
• wherein the pressure-sensitive adhesive layers for the upper and the lower polarizing plates comply with Equation 1 and Equation 2 below:
• ΔX=X1−X2=162 μm to 279 μm (1)
• X1 and X2=233 μm to 720 μm (2)
• wherein,
• X1 is a slid distance measured with respect to the pressure-sensitive adhesive layer for the upper polarizing plate after adhering the pressure-sensitive adhesive layer to a glass plate so as to have a contact area of 1 cm×1 cm and then applying a load of 1,000 gf at room temperature (25° C.) for 1,000 seconds,
• X2 is a slid distance measured with respect to the pressure-sensitive adhesive layer for the lower polarizing plate after adhering the pressure-sensitive adhesive layer to a glass plate so as to have a contact area of 1 cm×1 cm and then applying a load of 1,000 gf at room temperature (25° C.) for 1,000 seconds, and
• ΔX=X1−X2 is a difference between the slid distance measured with respect to the pressure-sensitive adhesive layer for the upper polarizing plate and the slid distance measured with respect to the pressure-sensitive adhesive layer for the lower polarizing plate.
