2 . The display device according to claim 1 , further comprising:
a scan driver that provides a scan signal for the pixel; and a data driver that provides a data signal for the pixel, wherein the scan driver and the data driver are disposed on a same side of the pixel part.

3 . The display device according to claim 2 , wherein
the display area includes a short side and a long side, and the scan driver and the data driver are disposed closer to the long side than the short side.

4 . The display device according to claim 2 , wherein
the first connection line includes a first scan line electrically connected to the at least one first pad part without being connected to the at least one second pad part, the second connection line includes a second scan line electrically connected to the first scan line, and the pixel is electrically connected to the at least one first pad part through the first scan line and the second scan line.

5 . The display device according to claim 4 , wherein
the first scan line is disposed in the first display area without being disposed in the second display area, and the second scan line is disposed in the first display area or disposed over the first display area and the second display area.

6 . The display device according to claim 4 , further comprising:
line parts each including a portion of the first connection lines and provided in a pattern repeatedly arranged multiple times, wherein the line parts include:
a first line part disposed in the first display area;
a second line part disposed in the second display area; and
a third line part,
the first line part includes the first scan line, the second line part and the third line part do not include the first scan line, the second line part includes the first extension data connection line, and the third line part does not include the first extension data connection line.

7 . The display device according to claim 6 , wherein the pixel disposed in the second display area receives a scan signal through the first scan line included in the first line part.

8 . The display device according to claim 6 , wherein
each of the first line part, the second line part, and the third line part includes data lines, and the first extension data connection line of the second line part is electrically connected to the data lines of the third line part through the second extension data connection line disposed in the second display area.

9 . The display device according to claim 6 , wherein at least part of connection lines of the second line part transmits a data signal provided to the third line part.

10 . The display device according to claim 6 , wherein
the first extension data connection line of the second line part includes:
a (1_1)-th data connection line;
a (2_1)-th data connection line; and
a (3_1)-th data connection line,
the second extension data connection line includes:
a (1_2)-th data connection line;
