  • Patent number: 11333915
    Abstract: The present disclosure provides a cover, a display device, and a method for manufacturing the display device. By forming a first via hole in an electronic component disposing region when an optically clear adhesive is formed on the cover, via holes are formed because the optically clear adhesive cannot form in the electronic component disposing region. Thus, the optically clear adhesive does not have portions having different thicknesses, thereby preventing bubbles from forming in a blind hole region, and solving technical problems of the existing display device that the OCA has bubbles around the corresponding blind hole region, which affects photographing quality.
