The invention provides a transparent adhesive sheet for flat panel display, which shows superior level difference absorbability and does not develop bubbles in the adhesion surface to a plastic plate. The transparent adhesive sheet for flat panel display is made of a cured product of a composition comprising (A) a polyoxyalkylene based polymer having at least one alkenyl group in one molecule, (B) a compound having an average of not less than 2 and less than 5 hydrosilyl groups in one molecule, and (C) a hydrosilylation catalyst, wherein the transparent adhesive sheet has a shear storage elastic modulus (G′) of not more than 1.0×105 Pa at 25° C. and 1 Hz, and a gel fraction of not less than 40%.
