Patent number: 10108034Abstract: 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.Type: GrantFiled: August 25, 2016Date of Patent: October 23, 2018Assignee: DEXERIALS CORPORATIONInventors: Kouichi Ogawa, Yoshihisa Shinya, Naoki Hayashi, Tomoyuki Toyoda

Publication number: 20180065354Abstract: 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.Type: ApplicationFiled: October 30, 2017Publication date: March 8, 2018Applicant: DEXERIALS CORPORATIONInventors: Kouichi OGAWA, Yoshihisa SHINYA, Naoki HAYASHI, Tomoyuki TOYODA

Patent number: 9885895Abstract: 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.Type: GrantFiled: September 21, 2015Date of Patent: February 6, 2018Assignee: DEXERIALS CORPORATIONInventors: Tomoyuki Toyoda, Yoshihisa Shinya, Yusuke Kamata

Publication number: 20170031203Abstract: A method for quickly applying and spreading adhesive between substrates without leaving air bubbles. The method includes holding two substrates apart from each other with adhesive sides facing, a second substrate being positioned above a first substrate. The second substrate is suspended in a manner so as to cause a portion to warp towards the first substrate. After a liquid filler is applied between the two substrates, rollers are lowered onto the second substrate and moved so as to disperse the liquid filler between the first and second substrates. In accordance with the rolling of the rollers, end portions of the second substrate are lowered towards the first substrate.Type: ApplicationFiled: October 13, 2016Publication date: February 2, 2017Applicant: DEXERIALS CORPORATIONInventors: Kouichi OGAWA, Yoshihisa SHINYA, Tomoyuki TOYODA, Yasumi ENDO

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
