Abstract

A display device in one embodiment includes a display panel configured to display an image in first and second display areas, a plurality of first gate lines corresponding to the first display area, and a plurality of second gate lines separated from the first gate lines and corresponding to the second display area. Accordingly, the distance between the first gate lines of the first display area and the second gate lines of the second display area is maximized to prevent static electricity from occurring between the electrodes, thereby increasing product yield.

First claim

What is claimed is:

1 . A display device comprising:
a display panel having a first display area and a second display area and configured to display an image in the first and second display areas; a plurality of first gate lines located on the display panel corresponding to the first display area; a plurality of second gate lines separated from the first gate lines and located on the display panel corresponding to the second display area; a plurality of first data lines provided on the display panel corresponding to the first display area to cross the first gate lines and defining a plurality of first pixel areas configuring the first display area; and a plurality of second data lines provided on the display panel corresponding to the second display area to cross the second gate lines and defining a plurality of second pixel areas configuring the second display area.

2 . The display device according to claim 1 , wherein the first gate lines and the second gate lines are separated from each other by a predetermined distance in a diagonal direction.

3 . The display device according to claim 1 , wherein the second gate lines are located in parallel above the first gate lines to correspond to each other in a diagonal direction.

4 . The display device according to claim 1 , further comprising:
first and second thin film transistors, wherein the second thin film transistors at intersections between the second gate lines and the second data lines are located above the first thin film transistors at intersections between the first gate lines and the first data lines to correspond to each other in a diagonal direction.

5 . The display device according to claim 1 , wherein a layout of the second gate lines and the second data lines is equal to a layout of the 180-degree rotated first gate lines and the first data lines.

6 . The display device according to claim 1 , wherein the first gate lines and the second gate lines are provided in parallel on the same line to be spaced apart from each other by a predetermined distance.

7 . The display device according to claim 1 , wherein the second gate lines overlap a second data line located at an outermost side of the second display area.

8 . The display device according to claim 1 , wherein the second gate lines are provided to be spaced apart from a second data line located at an outermost side of the second display area.

9 . The display device according to claim 1 , further comprising:
a first driving unit for providing first driving signals for displaying the image to the first gate lines and the first data lines; and a second driving unit for providing second driving signals for displaying the image to the second gate lines and the second data lines.

10 . The display device according to claim 9 , wherein the first driving unit includes:
a first gate driving unit for providing first gate signals to the first gate lines, a first data driving unit for providing first data signals to the first data lines, and a first timing controller for controlling the first gate driving unit and the first data driving unit, and wherein the first driving signals include the first gate signals and the first data signals.

11 . The display device according to claim 9 , wherein the second driving unit includes:
a second gate driving unit for providing second gate signals to the second gate lines, a second data driving unit for providing second data signals to the second data lines, and a second timing controller for controlling the second gate driving unit and the second data driving unit, and wherein the second driving signals include the second gate signals and the second data signals.

12 . The display device according to claim 1 , wherein the display device is any one of a liquid crystal display (LCD), an organic light emitting diode (OLED) display device, a curved display device, a rollable display device and a bendable display device.

13 . The display device according to claim 1 , wherein images implemented in the first display area and the second display area are different from or equal to each other.
