  • Patent number: 9046708
    Abstract: A display device includes a display panel, a protective plate which is provided opposed to the display panel, a member having touch sensor function, and a transparent organic layer which is provided between the display panel and the protective plate. The transparent organic layer includes an outer organic layer which is shaped like a frame to enclose at least a portion of an effective display area of the display panel, and an inner organic layer which is formed from the same material as the frame to fill a space enclosed by the frame. At least a part of the outer organic layer overlaps the effective display area of the display panel; and at least one of the display panel and the protective plate forms a portion of the member having touch sensor function.

  • Patent number: 8648818
    Abstract: Provided is a display device which is the liquid crystal display device (12) in which the transparent interlayer (3) is provided between the liquid crystal display panel (1) and the transparent substrate (11) having a touch panel function and disposed on a front side of the liquid crystal display panel (1). In the liquid crystal display device (12), the outermost periphery of the transparent interlayer (3) is shaped like a frame, and the same material is used to form a frame-shaped transparent interlayer (7) and the transparent interlayer (3) that constitutes an entire display area to prevent the liquid material of the interlayer (3) leaking out of the liquid crystal display device (12) during manufacture of a product or while the product is in use.
