Adhesives and image display apparatus using the same

An object of the present invention is to provide white turbidity even in a high-temperature and high-humidity environment when used between a front transparent plate and a touch panel, between a front transparent plate and an image display panel, or between a touch panel and an image display panel. Provided is a pressure-sensitive adhesive that is difficult and has step following ability. The pressure-sensitive adhesive of the present invention contains an acrylic base polymer and a hydrogenated terpene phenol resin having a softening point of 70 ° C to 150 ° C. The hydrogenated terpene phenol resin preferably has a terpene molar ratio of 0.1 to 0.7. The content of the acrylic base polymer is preferably 45 to 95 parts by weight relative to 100 parts by weight of the total amount of the pressure-sensitive adhesive composition. The total content of the acrylic base polymer and the hydrogenated terpene phenol resin is preferably 70 parts by weight or more. [Selection figure] None
