Suggested is an adhesive sheet that has one or more layers of a first adhesive layer and one or more layer of a second adhesive layer that exhibit different viscoelastic behaviors, and has an integrated structure whereby these layers are laminated, with a dynamic shear storage modulus G′ of 2×104 to 5×105 Pa for G′(20° C.) and 1×104 to 1×105 Pa for G′(150° C.) when measured with a 1 Hz frequency temperature dispersion.

Proposed is a surface protection panel disposed on the outer side of a liquid crystal display panel, that is to say, on the visible side of the liquid crystal display panel in a liquid crystal image display device equipped with a liquid crystal display panel. The surface protection panel has a constitution which a gas barrier transparent resin film having a gas barrier layer is layered on one side or on each side of a transparent synthetic resin plate, and the surface protection panel has a property which both the transparent synthetic resin plate and the gas barrier transparent resin film are non-stretched substantially, non-oriented or uniaxially oriented.
