Abstract: Provided is a pressure-sensitive adhesive composition. The pressure-sensitive adhesive composition may form a pressure-sensitive adhesive having a fine phase separation structure by a block copolymer including a hard segment and a soft segment, and also has a high elastic modulus and an excellent pressure-sensitive adhesive property. For example, although applied to a thin polarizing plate on at least one surface of which a polarizer protective film is not used, the pressure-sensitive adhesive may allow the polarizing plate to exhibit excellent durability, moisture resistance, workability, a pressure-sensitive adhesive property and a light leakage inhibiting ability.

Abstract: A pressure-sensitive adhesive composition, a pressure-sensitive adhesive polarizing plate and a liquid crystal display device are provided. The pressure-sensitive adhesive composition has excellent durability reliability under extreme conditions such as high temperature and/or humidity conditions, and shows superior workability such as cuttability or re-workability. Also, when the pressure-sensitive adhesive composition is applied to a polarizing plate or a liquid crystal display device, the composition can effectively prevent light leakage. Such a pressure-sensitive adhesive exhibits excellent characteristics, for example, even when the pressure-sensitive adhesive is applied to a 20-inch or more large display device.
