  • 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.
