In an image display device having a liquid crystal display panel 1 and a transparent protective panel 2 formed from a plastic which are arranged facing each other via a cured resin, an outer dimension of the protective panel 2 is made larger than an outer dimension of the liquid crystal display panel 1, curing of a resin composition 4 is carried out in a state where a peripheral edge of the protective panel 2 is fixed with a fixing jig 5, and the peripheral edge of the protective panel 2 is fixed with the fixing jig 5 even after the curing of the resin composition 4.

Abstract: An image display device has an image display part and a protective part on the image display part. The image display device suppresses image unevenness and cured resin peeling caused by internal stress generated due to curing shrinkage of a cured resin between the protective part and the image display part or external stress applied on the image display part due to warping of the protective part. A cured resin layer is arranged between the image display part and the protective part. The cured resin layer has a light transmittance in the visible region of 90% or more, an elongation ratio of 700% or more at 25° C. and 400% or more at 80° C., and an adhesive force with respect to the protective part of 0.4 N/cm or more at 25° C. and 0.3 N/cm or more at 80° C.

Abstract: A method for manufacturing an image display device includes the step of forming a cured resin layer by interposing a photo-curable resin composition between a protection member and a display-side panel including an image display unit and a frame member and then photo-curing the photo-curable resin composition, with the photo-curable resin composition being disposed across between the image display unit and the frame member. In the manufacturing method, a high-viscosity resin composition having a viscosity of 3000 mPa·s or more and 12000 mPa·s or less is used as the photo-curable resin composition. Alternatively, after a gap between the image display unit and the frame member is sealed with a sealing film, a photo-curable resin composition is interposed between the display-side panel and the protection member.

In the manufactured image display device, display defects caused by the deformation of the image display unit do not occur, and high-brightness and high-contrast display can be achieved. In addition, the resin in the area where the light-shielding member is formed can be sufficiently cured.

Abstract: It is possible to 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.
