Abstract
A display device includes a display area; a pad area including a first pad for supplying a data signal to the display area, second pads for transmitting a DC signal, and a dummy pad, wherein each of the first pad, the second pads, and the dummy pad has a surface as a top face thereof, wherein each of the surface of the first pad, the surface of the second pads, and the surface of the dummy pad has a corresponding vertical level in a thickness direction of the display device, wherein the vertical level of the surface of each of the second pads is higher than the vertical level of the surface of the first pad, wherein the vertical level of the surface of the dummy pad is lower than or equal to the vertical level of the surface of the first pad.
Claims20
A display device comprising:
- a display area;
- and
- a pad area that contains a first pad for supplying a data signal to the display area, a plurality of second pads located outside the first pad for transmitting a direct current (DC) signal, and a dummy pad located between the first pad and a group of the plurality of second pads,
- wherein the dummy pad is immediately adjacent to the first pad and the group of the plurality of second pads,
- wherein each of the first pad, the plurality of second pads, and the dummy pad has a surface as a top face thereof,
- wherein each of the surface of the first pad, the surface of the plurality of second pads, and the surface of the dummy pad has a corresponding vertical level in a thickness direction of the display device,
- wherein a vertical level of the surface of each of the plurality of second pads is higher than a vertical level of the surface of the first pad, and
- wherein a vertical level of the surface of the dummy pad is lower than or equal to the vertical level of the surface of the first pad.
A display device comprising:
- a display area;
- and
- a pad area that contains a first pad for supplying a data signal to the display area, a plurality of second pads located outside the first pad for transmitting a direct current (DC) signal, and a dummy pad located between the first pad and a group of the plurality of second pads,
- wherein the dummy pad is immediately adjacent to the first pad and the group of the plurality of second pads,
