  • Publication number: 20220352139
    Abstract: A display device including a display panel including a substrate, pixels provided on the substrate, and first lines connected to the pixels, the display device having a bending area where the display panel is bent. The display panel also includes a chip on film overlapping with a portion of the display panel and having second lines, an anisotropic conductive film provided between the chip on film and the display panel connecting the first lines and the second lines, and a coating layer covering the bending area and one end of the chip on film. In such a device, lines of the chip on film may be prevented from being corroded as they may be spaced apart from an edge of an insulating film.
