  • Patent number: 10290821
    Abstract: Provided is a display device having a substrate and a plurality of pixels. The substrate includes a first base film, a second base film; and a metal mesh which is located between the first base film and the second base film and has a first region and a second region. The pixels overlap with the first region through the second base film. The first region and the second region overlap with each other so that a part of the substrate overlaps with another part of the substrate, and a mesh size of the second region is larger than a mesh size of the first region.

  • Patent number: 10254799
    Abstract: A manufacturing method of a display device according to an embodiment of the present invention includes: a display panel forming process to provide a display panel includes the flexible base material, the plurality of pixels, and a display area, a display panel bending process to bend a part adjacent to the display area of the display panel and form a bent area, and arrange a part opposite to the display area with respect to the bent area to be opposed to the display area, a filling process to fill, by liquid adhesive, a space on the inner surface side that is in the bent area and that is the surface side of the display panel opposite to the surface on which the plurality of pixels are arranged on the flexible base material, and a curing process to cure the liquid adhesive and form an adhesive layer.

  • Publication number: 20170263689
    Abstract: A display device includes a first substrate, a second substrate facing the first substrate, an IC chip mounted in a non-facing region of a surface of the first substrate, a terminal formed between the IC chip and an edge of the first substrate in the non-facing region, and an FPC connected to the terminal. The surface of the first substrate faces the second substrate. The non-facing region is formed between the edge of the first substrate and an edge of the second substrate. The non-facing region does not face the second substrate. The FPC includes a terminal covering portion covering the terminal and connected to the terminal, and a lateral covering portion covering a lateral portion of the non-facing region. The lateral portion is located in a direction along the edge of the second substrate with respect to the IC chip. The lateral covering portion is attached to the lateral portion.
