Abstract: In the method of manufacturing an image display apparatus according to the present invention, a liquid photocurable resin composition that does not contain a thermal polymerization initiator is coated on the surface of a light-transmissive cover member including a light shielding layer or the surface of an image display member in a thickness thicker than that of the light shielding layer, and thereafter UV rays are irradiated in that state for curing to form a light-transmissive cured resin layer. Then, the image display member and the light-transmissive cover member are laminated to each other via the light-transmissive cured resin layer to obtain an image display apparatus.

Abstract: An image display device, and a production method thereof are provided, which maximize suppression of warping of a protective panel. A liquid crystal display panel and a transparent protective panel formed from a plastic are arranged facing each other via a cured resin. An outer dimension of the protective panel is made larger than an outer dimension of the display panel. Curing is carried out with an edge of the protective panel fixed with a fixing jig during and after curing. Alternatively, the outer dimension of the protective panel is substantially equal to an outer dimension of the display panel, which is substantially equal to an inner dimension of a case and the protective panel. Curing is carried out with the resin composition in contact with substantially the whole face of the protective panel.

Abstract: An image display device is manufactured by: applying a liquid photo-curable resin composition having a total value of cure shrinkage ratios based on pre-curing and complete curing of 3% or more to a surface of the light-transmitting cover member or a surface of the image display member with a thickness greater than that of the light-shielding layer to cancel the step between the light-shielding layer and the light-shielding layer forming surface of the light-transmitting cover member; pre-curing the photo-curable resin composition with the irradiation of ultraviolet rays to form a pre-cured resin layer; bonding the light-transmitting cover member to the image display member such that the pre-cured resin layer is placed inside; and subjecting the pre-cured resin layer to the irradiation of ultraviolet rays to achieve the complete curing thereof. The pre-curing is conducted to obtain a cure shrinkage ratio less than 3% in the complete curing thereof.
