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.
Claims20
A display device, comprising:
- a display panel comprising a substrate, pixels provided on the substrate, and first lines connected to the pixels, wherein the display panel comprises a bending area where the display panel is bent;
- a first coating layer provided in an end portion of the display panel;
- and
- an anisotropic conductive film disposed on the substrate of the display panel and connected to the first lines.
A display device, comprising:
- a display panel comprising a substrate, pixels provided on the substrate, and first lines connected to the pixels, wherein the display panel comprises a bending area where the display panel is bent;
- a chip on film overlapping with a portion of the display panel and comprising second lines, the chip on film comprising an insulating film including a first surface and a second surface, the second lines on the first surface, and pads disposed on each of the second lines;
- an anisotropic conductive film provided between the chip on film and the display panel to connect the first lines and the second lines;
- and
- a coating layer overlapping with one end of the chip on film in the bending area,
- wherein:
- pads have a first width and a second width positioned sequentially in a direction moving away from an edge of the insulating film;
- and
- the first width and the second width are different from each other.
A display device, comprising:
- a display panel comprising a substrate, pixels provided on the substrate, and first lines connected to the pixels, wherein the display panel comprises a bending area where the display panel is bent;
