  • Patent number: 11480820
    Abstract: A display device improves ESD resistance while using a plurality of adhesive double-sided tapes for fixing a display. After an OGS and a liquid crystal display are bonded to each other to be integrated, an outer edge portion of the OGS is bonded and fixed to a frame housing a backlight unit by four adhesive double-sided tapes. The four adhesive double-sided tapes are arranged to substantially surround a central region with a slight gap between adjacent ones of the adhesive double-sided tapes. An end portion of each of the adhesive double-sided tapes is set to have a shape such that a narrow path is bent, rather than being straight, the narrow path being a space surrounded by end surfaces of the two adhesive double-sided tapes between the frame and the OGS and extending narrowly.
