Provided are: a pressure-sensitive adhesive composition which has excellent conformability to ruggedness at the time of bonding to adherends and which after the bonding, can be inhibited from suffering delayed bubbles, lifting, or peeling; and a pressure-sensitive adhesive sheet which includes a pressure-sensitive adhesive layer comprising the pressure-sensitive adhesive composition. Also provided are a touch panel and a display device which include the pressure-sensitive adhesive sheet and can be effectively inhibited from suffering delayed bubbles, etc. after bonding. The pressure-sensitive adhesive composition comprises an acrylic ester copolymer having a crosslinkable functional group, an oligomer having two or more polymerizable unsaturated groups, a monomer having both a functional group reacting with the acrylic ester copolymer and a functional group reacting with the oligomer, a crosslinking agent which reacts with the acrylic ester copolymer by the action of heat, and a polymerization initiator for initiating the polymerization reaction upon irradiation with actinic rays. |
