2 . The display apparatus of claim 1 , wherein the first scan line is configured to receive a first scan signal from the first gate driver and transmit the first scan signal to the first pixel group, and
wherein the third scan line is configured to receive the first scan signal through the first horizontal scan line and transmit the first scan signal to the third pixel group.

3 . The display apparatus of claim 2 , further comprising:
a fourth scan line extending in the first direction in a plan view and connecting the first gate driver and the fourth pixel group to each other; and a second horizontal scan line extending in the second direction in a plan view and connecting the second scan line and the fourth scan line to each other.

4 . The display apparatus of claim 3 , wherein the second scan line is configured to receive a second scan signal from the first gate driver and transmit the second scan signal to the second pixel group, and
wherein the fourth scan line is configured to receive the second scan signal through the second horizontal scan line and transmit the second scan signal to the fourth pixel group.

5 . The display apparatus of claim 1 , further comprising:
a first data line connected to a display element of the first pixel group and extending in the second direction in a plan view; and a first vertical data line extending in the first direction in a plan view and connecting the first data line and the data driver to each other.

6 . The display apparatus of claim 5 , wherein, in a plan view, the first gate driver is located at one side of the first peripheral area, and the data driver is located at an other side of the first peripheral area.

7 . The display apparatus of claim 6 , wherein, in a plan view, the first vertical data line is in an area of the display area, the area corresponding to the other side of the first peripheral area.

8 . The display apparatus of claim 7 , wherein, in a plan view, the first scan line is in an area of the display area, the area corresponding to the one side of the first peripheral area.

9 . The display apparatus of claim 1 , further comprising a plurality of scan lines comprising at least the first scan line, the second scan line, and the third scan line,
wherein the first horizontal scan line is connected to 4n scan lines from among the plurality of scan lines.

10 . The display apparatus of claim 9 , wherein one scan line from among the 4n scan lines is connected to the first gate driver, and the 4n scan lines are configured to receive a same scan signal generated by the first gate driver.

11 . A display apparatus comprising:
a substrate including a display area and a first peripheral area, the first peripheral area being on one side of the display area; a first gate driver in the first peripheral area; a data driver in the first peripheral area; a second gate driver in the first peripheral area, wherein, in a plan view, the second gate driver is between the first gate driver and the data driver; a plurality of pixel groups in the display area and comprising a plurality of display elements arranged along a first direction in a plan view; and a plurality of scan lines extending in the first direction in a plan view, wherein some scan lines from among the plurality of scan lines are connected to the first gate driver and other scan lines from among the plurality of scan lines are connected to the second gate driver, wherein the some scan lines and the other scan lines are connected to each other by a plurality of horizontal scan lines.

12 . The display apparatus of claim 11 , wherein the plurality of pixel groups comprises at least a first pixel group, a second pixel group, a third pixel group, a fourth pixel group, a fifth pixel group, a sixth pixel group, a seventh pixel group, and an eighth pixel group, and
wherein the plurality of scan lines comprises a first scan line, a second scan line, a third scan line, a fourth scan line, a fifth scan line, a sixth scan line, a seventh scan line, and an eighth scan line respectively connected to the first pixel group to the eighth pixel group.

13 . The display apparatus of claim 12 , wherein the plurality of horizontal scan lines comprises a first horizontal scan line, and
wherein the first scan line is connected to the first pixel group and connected to the fifth scan line and the seventh scan line by the first horizontal scan line.

14 . The display apparatus of claim 13 , wherein the plurality of horizontal scan lines further comprises a first additional horizontal scan line, and
wherein the seventh scan line is connected to the third scan line by the first additional horizontal scan line.

15 . The display apparatus of claim 14 , wherein, in a plan view, the first horizontal scan line and the first additional horizontal scan line are spaced from each other in the first direction.

16 . The display apparatus of claim 14 , wherein the first pixel group, the third pixel group, the fifth pixel group, and the seventh pixel group are configured to receive a same scan signal generated by the first gate driver.

17 . The display apparatus of claim 14 , wherein the first scan line is connected to the first gate driver, and the third scan line is connected to the second gate driver.
