Provided is a polymerizable composition that is interposed between an image display part and a transparent protection part of an image display device and polymerized in order to form a polymer layer, said polymerizable composition exhibiting a small volume shrinkage rate at the time of polymerization and enabling the production of a polymer which exhibits low permittivity and reduced discoloration due to heat, and which is highly adhesive to materials used in the transparent protection part, e.g. glass. The polymerizable composition according to the present invention contains: (component 1) at least one compound selected from the group consisting of compounds including a (meth)acryloyl group having a polyolefin structural unit, compounds including a (meth)acryloyl group having a hydrogenated polyolefin structural unit, compounds including a (meth)acryloyl group having a (poly)ester structural unit, and compounds including a (meth)acryloyl group having a (poly)carbonate structural unit; (component 2) a (meth)a
