  • Patent number: 8952911
    Abstract: An electronic display device being arrangeable during use into one of at least an opened and a closed state. The device includes a deformable display panel having an active area, a periphery area adjacent the active area, and a drive circuit for driving the active area. The active area includes an active area conductive structure substantially arranged along a front side of the active area. The periphery area includes a frame structure for visually bounding the active area. The frame structure is conformal to the display panel. The frame structure is electrically conductive and an insulator structure is provided between the active area conductive structure and the conductive frame structure. The insulator structure insulates the active area conductive structure from frame structure, the conductive frame structure being arranged to thereby shield the active area against ESD damage.

  • Patent number: 8829527
    Abstract: The present invention provides a method for manufacturing a highly reliable display device at a low cost with high yield. According to the present invention, a step due to an opening in a contact is covered with an insulating layer to reduce the step, and is processed into a gentle shape. A wiring or the like is formed to be in contact with the insulating layer and thus the coverage of the wiring or the like is enhanced. In addition, deterioration of a light-emitting element due to contaminants such as water can be prevented by sealing a layer including an organic material that has water permeability in a display device with a sealing material. Since the sealing material is formed in a portion of a driver circuit region in the display device, the frame margin of the display device can be narrowed.

  • Patent number: 8821966
    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.
