A method for manufacturing an image display device includes applying a first photo-curable resin composition to a protective panel to form a first photo-curable resin composition layer. The first photo-curable resin composition layer is irradiated with curing light to form a first cured resin layer. A second photo-curable resin composition is applied to the first cured resin layer to form a second photo-curable resin composition layer. The second photo-curable resin composition layer has a reduced or eliminated height difference, compared with the first photo-curable resin composition layer. The protective panel and an image display member are laminated via the second photo-curable resin composition layer. The second photo-curable resin composition layer is irradiated with curing light.

The present invention provides an improved method for curing multi-layer constructs of energy curable (EC) inks and coatings with actinic radiation. In the method, one or more layers of EC inks and/or coatings comprising materials that can crosslink or polymerize when exposured to actinic radiation, e.g., monomers, oligomers or polymers, are applied to a substrate, which EC inks and coatings contain little or no photoinitiators. This is followed by applying one or more layers of non-EC inks and/or coatings, which comprise one or more organic peroxides but no readily polymerizable components, over the top of the layers of energy curable inks and/or coatings; and exposing the layers to actinic radiation.
