The present invention relates to a pressure-sensitive adhesive composition used for an optical filter of a display panel, comprising: (A) a near-infrared ray composed of a (meth) acrylic acid ester copolymer having a crosslinkable functional group in a molecule, (B) a crosslinking agent, and (C) a composite tungsten oxide It contains a water absorbent, and after crosslinking, storage elastic modulus (G ') at the temperature of 80 degreeC is 1 * 10 < 4> -1 * 10 < 6> Pa, and glass transition temperature (Tg) is -30 degreeC or more, It is characterized by the above-mentioned. It is a pressure-sensitive adhesive composition for displays. Pressure-sensitive adhesive for display, which has excellent optical properties while providing a low-cost optical filter while simplifying the layer structure of optical filters such as plasma display panels and liquid crystal display panels, in which various functional films are laminated, and having excellent durability and weather resistance. A composition is provided. |
