  • Patent number: 11772364
    Abstract: A display device according to embodiments of the present disclosure includes a display panel, a protection member to protect the display panel, and an adhesive member between the display panel and the protection member to couple the display panel to the protection member. The display panel may include a plurality of pixels to display an image, and the adhesive member may include an adhesive agent and an anti-static agent dispersed in the adhesive agent. The anti-static agent may include halogen ions, and a content of halogen ions with respect to a total weight of the adhesive agent may be within a range (e.g., from about 1 ppm to about 1000 ppm) capable of reducing stain failures caused by static electricity, without causing corrosion of driving lines in the display.

  • Patent number: 9825108
    Abstract: A curved display device is disclosed. In one aspect, the display device includes a substrate comprising a flat portion and at least one curved portion, a display unit comprising a first display area on the flat portion, and a second display area on the curved portion, and a thin-film encapsulating layer sealing the display unit, and comprising at least one organic layer and at least one inorganic layer. The display device also includes a functional layer over the thin-film encapsulating layer, wherein the thin-film encapsulating layer comprises a first region overlapping the curved portion, and a second region overlapping the flat portion. The inorganic layer contacts the functional layer, and wherein the inorganic layer has a first surface roughness in the first region different from a second surface roughness in the second region.
