a first gate driving circuit arranged on the second corner display area of the substrate;
a first line connected to the first gate driving circuit and extending toward the main display area; and
a second line connected to the first gate driving circuit and extending toward the first corner display area.

2. The display panel of claim 1 , further comprising:
a corner light emitting device arranged on the second corner display area of the substrate; and
a pixel circuit connected to the corner light emitting device and which drives the corner light emitting device,
wherein the pixel circuit is arranged in the main display area or the first corner display area.

3. The display panel of claim 2 , wherein the pixel circuit includes:
a semiconductor layer arranged on the substrate; and
a gate electrode arranged on the semiconductor layer and overlapping at least a part of the semiconductor layer in a plan view,
wherein the first line and the second line each include a same material as the gate electrode.

4. The display panel of claim 1 , further comprising:
a second gate driving circuit arranged in the second corner display area and spaced apart from the first gate driving circuit; and
a first bridge line connected to the first line and the second line through contact holes and arranged between the first gate driving circuit and the second gate driving circuit.

5. The display panel of claim 1 , wherein the first line and the second line are provided in plural,
a (1-1) st line among the plurality of first lines is connected to a (2-1) st line among the plurality of second lines, and
in a state where the substrate is unfolded, a virtual extending line of the (2-1) st line is on the same line as a (1-2) nd line.

6. The display panel of claim 1 , wherein the first corner display area of the substrate includes:
a plurality of strip portions extending from the second corner display area toward the peripheral area; and
a plurality of through-portions is defined between the plurality of strip portions and passes through the substrate.

7. The display panel of claim 6 , wherein an area of the plurality of through-portions varies with a force applied to the first corner display area.

8. The display panel of claim 1 , wherein the first corner display area of the substrate includes:
a plurality of islands;
a plurality of connection portions connecting the plurality of islands to each other; and
a plurality of through-portions is defined between the plurality of islands and the plurality of connection portions and passes through the substrate.

9. The display panel of claim 1 , further comprising a third line arranged on the main display area, the first corner display area, and the second corner display area of the substrate and extending in a direction intersecting with the first line.

10. The display panel of claim 1 , further comprising:
