Abstract

A display apparatus includes first and second display areas, first pixels in the first display area, and second pixels in the second display area. Gate lines are connected to the first pixels. First gate electrode lines are connected to the second pixels. First gate driving lines are respectively connected to the first gate electrode lines. A first gate driver outputs first scanning signals to the first pixels via the gate lines. A second gate driver outputs second scanning signals to the second pixels via the first gate driving lines and the first gate electrode lines.

an edge non-display area surrounding the display area;
an inner non-display area between the first display area and the second display area and adjacent to the third display area in a direction opposite to the first direction; and
a through hole that penetrates through the substrate in the inner non-display area of the display;

a display including:
a plurality of pixels including first pixels in the first display area, second pixels in the second display area, and third pixels in the third display area;
a plurality of gate lines extending in the first direction and connected to the first pixels and not connected to the second pixels;
a plurality of first gate electrode lines extending in the first direction and connected to the second pixels and not connected to the first pixels; and
a plurality of first gate driving lines extending in the second direction different from the first direction, the first gate driving lines respectively connected to the first gate electrode lines;

a first gate driver to output first scanning signals to the first pixels via the gate lines; and
a second gate driver to output second scanning signals to the second pixels via the first gate driving lines and the first gate electrode lines.

2. The display apparatus as claimed in claim 1 , wherein a first scanning period for the first gate driver to output the first scanning signals is shorter than a second scanning period for the second gate driver to output the second scanning signals.

3. The display apparatus as claimed in claim 1 , wherein:
within a single frame period, the second gate driver is to output the second scanning signals to the second pixels after the first gate driver outputs the first scanning signals to the first pixels.

4. The display apparatus as claimed in claim 1 , wherein: the display includes a plurality of data lines extending in the second direction and connected to the first pixels and the second pixels, and
the data lines include first data lines including first portions and second portions, the second portions being separated from second first portions by the through hole in the second direction and second data lines spaced from the through hole in the first direction and electrically and respectively connected to the second portions of the first data lines.

5. The display apparatus as claimed in claim 4 , further comprising:
a plurality of data connecting lines connecting the second portions of the first data lines to the second data lines, respectively.

6. The display apparatus as claimed in claim 4 , wherein the second pixels are connected to the second portions of the first data lines.

7. The display apparatus as claimed in claim 4 , wherein: the data lines include third data lines spaced from the through hole in the first direction,
and the second data lines are between the first data lines and the third data lines in the first direction.

8. The display apparatus as claimed in claim 1 , wherein the inner non-display area is adjacent to the edge non-display area.

9. The display apparatus as claimed in claim 1 , wherein:
the display includes:
a plurality of second gate electrode lines extending in the first direction and connected to the third pixels; and
a plurality of second gate driving lines extending in the second direction and respectively connected to the second gate electrode lines,
the second gate driver is to output third scanning signals to the third pixels via the second gate driving lines and the second gate electrode lines.

10. The display apparatus as claimed in claim 9 , wherein:
within a single frame period, a time period for the second gate driver to output the third scanning signals to the third pixels is between a time period for the first gate driver to output the first scanning signals to the first pixels and a time period for the second gate driver to output the second scanning signals to the second pixels.

11. The display apparatus as claimed in claim 9 , wherein:
the display area includes a fourth display area adjacent to the first display area in the second direction,
the second display area and the inner non-display area are between the third display area and the fourth display area in the first direction, and
the pixels includes a plurality of fourth pixels in the fourth display area.

12. The display apparatus as claimed in claim 11 , wherein:
the display includes:
third gate electrode lines extending in the first direction and connected to the fourth pixels; and
third gate electrode lines extending in the second direction and respectively connected to the third gate electrode lines,
