Abstract: According to a method of manufacturing an image display device of the present invention, a photo-curable resin composition in a liquid state is applied to a surface of a light-transmitting cover member including a light-shielding layer or a surface of the image display member to a thickness greater than that of the light-shielding layer. Then, in this state, the photo-curable resin composition is irradiated with a UV ray to be pre-cured, thereby forming a pre-cured resin layer. Next, the image display member and the light-transmitting cover member are stacked via the pre-cured resin layer and thereafter, the pre-cured resin layer is irradiated with a UV ray to be completely cured, thereby forming a light-transmitting cured resin layer.

Abstract: A method for producing a bonded plate-shaped assembly includes retaining a pair of plate-shaped members facing each other by a pair of retaining base members; charging a photo-curable liquid material between the pair of plate-shaped members facing each other; causing movement of the pair of retaining base members by a retaining base member movement unit to cause the pair of plate-shaped members to draw close to each other to cause wetting spreading of the liquid material between the pair of plate-shaped members; detecting a wetting spreading state of the liquid material by a sensor; and illuminating curing light, in response to the result of detection, to the liquid material wettingly spread to the entire surfaces of the pair of plate-shaped members, to form the bonded plate-shaped assembly made up of the pair of plate-shaped members bonded together.

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: 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.
