Abstract: In relation to a polymerizable composition for forming a transparent optical resin layer to be interposed between an image display section of an image display device and a light-transmissive protective section thereof, the present invention provides a polymerizable composition that does not give rise to display defects caused by the deformation of the image display section, enables high-luminance, high-contrast image displaying, has excellent heat resistance, and also has a low dielectric constant. This polymerizable composition comprises: (1) a urethane (meth)acrylate obtained by reacting a hydrogenated polyolefin polyol and a compound having an isocyanato group and a (meth)acryloyl group; (2) a (meth)acryloyl-group-containing compound having a hydrocarbon group with a carbon number of 6 or greater; and (3) a photopolymerization initiator.
