摘要：
The present invention provides an optically clear adhesive sheet having excellent environment resistance using a heat-curable polyurethane composition that has excellent flexibility and is capable of giving a thick film. The optically clear adhesive sheet of the present invention is formed of: a cured product of a heat-curable polyurethane composition, the heat-curable polyurethane composition containing a polyol component, a polyisocyanate component, and a tackifier, the polyol component having an olefin skeleton, the polyisocyanate component being a modified polyisocyanate that is obtained by reacting an acyclic aliphatic and/or alicyclic polyisocyanate containing an isocyanate group with an ether compound containing an ethylene oxide unit.
