Abstract
An adhesive composition according to an embodiment includes an acrylic copolymer, and a compound containing a sulfide group and having a refractive index of 1.57 or more. The adhesive sheet prepared from the adhesive composition may have a low glass transition temperature and high refractive index, such that an image display device may not include a separate high refractive index pattern layer.
