Abstract
Manufacture a highly reliable image display device capable of proceeding with resin cure even in the case where a protective panel is provided with a light shielding portion. A liquid crystal display unit 2 having a liquid crystal display panel 8 and a light transmissive protective panel 3 having a light shielding portion 5 are disposed face to face, a resin composition 10 is interposed between the liquid crystal display unit and the protective panel, and the resin composition is cured into a cured resin layer 11. As the resin composition 10, a light-heat-curing resin composition and containing a photopolymerization initiator and organic peroxide of thermal polymerization initiator is used. In curing the resin composition 10, cure by light (ultraviolet rays) irradiation is performed until a cure ratio of the resin composition becomes 30% or more and thereafter thermal cure is performed.
