Polymerizable composition, polymerization product, image display device, and method for producing same

A polymerization product used as a transparent optical resin layer interposed between an image display portion and a light-transmitting protective portion of an image display device;

• wherein, the dielectric constant of the polymerization product under conditions of a temperature of 23° C., frequency of 100 kHz and applied voltage of 100 mV is 3.0 or less, and the color coordinate b* value described in JIS Z 8729 of the polymerization product present between two glass plates and adjusted to a thickness of 200 μm after storing under conditions of a temperature of 95° C. for 500 hours is less than 1.0.
