摘要： 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.

摘要： Provided are a pressure sensitive adhesive composition, a protective film, an optical film and a display device. The pressure sensitive adhesive composition shows appropriate low-speed and high-speed peel strengths after formation of a cross-linked structure, and has a superior balance between the two. Accordingly, when the pressure sensitive adhesive composition is applied to a protective film, for example, a superior protection effect as well as easy peel-off upon high-speed peeling, which is advantageous for a high-speed process, are shown, and in addition, a superior antistatic property may be obtained during the process.
