Abstract: Provided are: a pressure-sensitive adhesive composition for optical members having excellent durability, adhesiveness (adhesion), and removability; a pressure-sensitive adhesive layer for optical members that uses the pressure-sensitive adhesive composition; an adhesive optical member; and an image display device. The pressure-sensitive adhesive composition for optical members is characterized by containing 0.02 to 5 parts by weight of a curing catalyst, and 0.2 to 5 parts by weight of an isocyanate compound, with respect to 100 parts by weight of a polymer having a reactive silicon group with a weight average molecular weight of 2000 to 50000 on or near a molecular terminal.
