摘要:
Provided are a pressure-sensitive adhesive composition, an optical member, a polarizing plate and a display device. The pressure-sensitive adhesive composition having physical properties required for an optical member using a particular block copolymer and an antioxidant or a photostabilizer, which forms a fine phase change region in a crosslinking structure, and particularly having excellent bending preventability and storage stability may be provided. Such a pressure-sensitive adhesive composition may be used for optical uses, for example, to laminate various optical members, or apply an optical member to a display device.
