Abstract
A laminate body () is provided with a transparent substrate () and a refractive layer () which refracts incident light towards the top of the substrate (). The refractive layer () contains, at least, one kind of fluorine compound (ss) selected from a group consisting of fluoro-silsesquioxane and fluoro-silsesquioxane polymers, and a resin (pl) having a refractive index higher than that of the aforementioned fluorine compound (ss). Of the side of the substrate () (the side of the back surface s) and the side opposite thereof (the side of the front surface s), the concentration of the fluorine compound (ss) in the refractive layer () is higher on said side opposite (the side of the front surface s), and the refractive layer () forms a graded structure layer of high refractive indices and low refractive indices inside the layer.
