Patent number: 9354462Abstract: 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.Type: GrantFiled: January 4, 2016Date of Patent: May 31, 2016Assignee: DEXERIALS CORPORATIONInventors: Tomoyuki Toyoda, Yoshihisa Shinya, Yusuke Kamata

Patent number: 8087967Abstract: 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.Type: GrantFiled: July 16, 2008Date of Patent: January 3, 2012Assignee: Sony Chemical & Information Device CorporationInventors: Yoshihisa Shinya, Kenji Kamiya, Yusuke Kamata
