The present invention provides an impact absorption sheet for flat panel display with a polyoxyalkylene-series polymer as the main component, preferably, an impact absorption sheet for flat panel display made of a cured product obtained by curing a composition containing (A) polyoxyalkylene-series polymer having at least one alkenyl group in each molecule, (B) compound having an average of 2 or more hydrosilyl groups in each molecule, and (C) hydrosilylation catalyst.According to the present invention, an impact absorption sheet for flat panel display can be obtained, which can meet the size reduction and weight reduction of flat panel display, and which affords practically sufficient impact absorbability even in an area of thin film where practically sufficient impact absorbability has not been conventionally achieved. According to the present invention, moreover, an impact absorption sheet for flat panel display can be obtained, which not only has superior impact absorbability but is also superior in easy adhesion to flat panel display and redetachability after adhesion.
