Display device
A display device includes a plurality of gate lines extending in a first direction on the display area, a plurality of source lines extending in a second direction, a plurality of lead-out lines extending in the second direction and for transmitting gate signals to the plurality of gate lines. A plurality of connecting portions each electrically connects one gate line to one lead-out line. The plurality of connecting portions pass through a first insulating layer at a plurality of jointing points which are selected among a plurality of overlapping points where the plurality of lead-out lines and the plurality of gate lines overlap in a plane area.
1. A display device for displaying an image in a display area in accordance with image signals, the display device comprising:
a plurality of gate lines extending in a first direction on the display area;
a plurality of source lines extending in a second direction which is different from the first direction;
a plurality of lead-out lines extending in the second direction and for transmitting gate signals to the plurality of gate lines; and
a plurality of common lines extending in the second direction for providing a common voltage to a common electrode,
wherein a number of the plurality of source lines is larger than a number of the plurality of lead-out lines, and the plurality of source lines include a first source line extending along one of the plurality of lead-out lines, and a second source line extending along one of the plurality of common lines.
2. The display device according to claim 1 , further comprising a first insulating layer formed between the plurality of lead-out lines and the plurality of gate lines; and
a plurality of connecting portions each electrically connecting one of the plurality of gate lines to one of the plurality of lead-out lines.
3. The display device according to claim 1 , wherein each of the plurality of source lines extending along either one of the plurality of lead-out lines or one of the plurality of common lines.
4. The display device according to claim 1 , wherein the plurality of common lines include a first common line, a second common line and a third common line, the first common line, the second common line and the third common line arranged adjacent to each other in this order,
a number of the plurality of lead-out lines formed between the first common line and the second common line is the same as the number of the plurality of lead-out lines formed between the second common line and the third common line.
5. The display device according to claim 1 , wherein the plurality of common lines and the plurality of lead-out lines are formed in the same layer.
6. The display device according to claim 5 , further comprising:
a second insulating layer formed between the plurality of source lines and the plurality of common lines; and
a third insulating layer formed between the plurality of source lines and the common electrode, wherein
the plurality of common lines provide the common voltage to the common electrode via a through hole formed in the second insulating layer and the third insulating layer.
