Patent number: 11772364Abstract: 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.Type: GrantFiled: August 11, 2022Date of Patent: October 3, 2023Assignee: Samsung Display Co., Ltd.Inventors: Jonggil Ryu, Seungmin Lee, Jonghak Hwang, Kwangnyun Kim, Chulkyu Choi, Namjin Kim
