1. A display panel comprising:
a display substrate having a display area to display an image, and a pad area disposed on at least one side of the display area; and
a plurality of pads arranged on the pad area in a first direction, the plurality of pads comprises:
a plurality of first pads, and each of the first pads has an each first inclination with respect to a first reference line that is parallel to a second direction normal to the first direction; and
a plurality of second pads, and each of the second pads has an each second inclination, which is different from the each first inclination, with respect to the first reference line, and
wherein one of a second reference line and a third reference line defined by connection of respective ends of the first pads and the second pads is a curved line and the other one of the second reference line and the third reference line is a straight line or a substantially straight line, and
wherein the second reference line is defined adjacent to the display area, and the third reference line is defined adjacent to an edge of the display substrate,
wherein the plurality of pads arranged in a plurality of pad groups, and the plurality of pad groups comprises:
a first pad group is disposed on a central portion of the pad area; and
a second pad group is disposed on at least one side of the first pad group, and
wherein the first pad group includes the first pads, and the second pad group includes the second pads,
wherein the first pads in the first pad group are spaced from each other at a first pitch,
wherein the second pads in the second pad group are spaced from each other at a second pitch different from the first pitch,
wherein the second pad group comprises:
a plurality of first sub pad groups disposed on one side of the first pad group; and
a plurality of second sub pad groups disposed on the other side of the first pad group, and wherein each of the first sub pad groups and the second sub pad groups comprises the second pads,
wherein the second inclinations of the second pads of the first sub pad groups increase in the first direction outwardly from the central portion toward the end of the pad area, and
wherein the second pitch between the second pads decreases in the first direction outwardly from the central portion toward the end of the pad area.
