Patent number: 9279911Abstract: 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: June 9, 2014Date of Patent: March 8, 2016Assignee: DEXERIALS CORPORATIONInventors: Tomoyuki Toyoda, Yoshihisa Shinya, Yusuke Kamata

Publication number: 20160011454Abstract: 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: ApplicationFiled: September 21, 2015Publication date: January 14, 2016Applicant: DEXIRIALS CORPORATIONInventors: Tomoyuki TOYODA, Yoshihisa SHINYA, Yusuke KAMATA

Patent number: 9182625Abstract: A display having high re-workability, a method for producing the display, and a transparent resin filler, are provided. A transparent resin filler (5), in which a value obtained on multiplying a hardness of an as-cured resin, expressed as Shore E, with a bonding strength, is not greater than 400, is used as a material of a transparent resin layer (4) to be charged between a picture image display panel (2) and a front side panel (3). In case an undesirable situation, such as mixing of foreign matter in the transparent resin layer (4), has occurred, a re-working member may be moved with ease through a space between the picture image display panel (2) and the front side panel (3) to separate picture image display panel (2) and the front side panel (3) from each other.Type: GrantFiled: October 16, 2009Date of Patent: November 10, 2015Assignee: Dexerials CorporationInventors: Yuki Watanabe, Yoshihisa Shinya, Kenji Kamiya

Publication number: 20150000836Abstract: 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: September 15, 2014Publication date: January 1, 2015Inventors: Kouichi OGAWA, Yoshihisa SHINYA, Naoki HAYASHI, Tomoyuki TOYODA

Patent number: 8710662Abstract: A light-reflective anisotropic conductive paste is used as an anisotropic conductive paste when a light-emitting device is produced by flip-chip mounting a light-emitting element such as a light-emitting diode element (LED) on a wiring board. The light-reflective anisotropic conductive paste includes light-reflective insulating particles, in order to improve light emission efficiency without providing, in the LED, a light-reflecting layer that causes an increase in manufacturing cost. With the light-reflective anisotropic conductive paste, a reduction in bonding strength of the light-emitting element to the wiring board in a high-temperature environment can be suppressed, and a reduction in conduction reliability after a TCT can also be suppressed. In the light-reflective anisotropic conductive paste, conductive particles and the light-reflective insulating particles are dispersed in a thermosetting resin composition.Type: GrantFiled: May 27, 2011Date of Patent: April 29, 2014Assignee: Sony Corporation & Information Device CorporationInventors: Hideaki Umakoshi, Hidetsugu Namiki, Akira Ishigami, Masaharu Aoki, Shiyuki Kanisawa, Yoshihisa Shinya
