Abstract

A display device may include a substrate; a plurality of signal lines on the substrate; a plurality of scan lines on the substrate, the scan lines crossing the signal lines; and a plurality of thin film transistors at crossing positions of the scan lines and the signal lines. The scan lines include some first scan lines and some second scan lines. Each of the second scan lines has an end connected to a load element.

Claims (22)

1. A display device comprising:

a substrate having a display area and a non-display area;

a plurality of signal lines extending in a first direction within the display area;

a plurality of scan lines extending in a second direction crossing the signal lines within the display area;

a plurality of thin film transistors disposed in the display area; and

a scanning circuit disposed along an edge of the substrate, wherein

the scan lines include a first scan line, a second scan line and a third scan line,

a first end of the first scan line, a second end of the second scan line and a third end of the third scan line are connected to the scanning circuit,

a first number of the thin film transistors is connected to the first scan line, a second number of the thin film transistors is connected to the second scan line, a third number of the thin film transistors is connected to the third scan line within the display area,

the second number is smaller than the first number, and the third number is smaller than the second number,

the first scan line includes a fourth end, the second scan line includes a fifth end, and the third scan line includes a sixth end;

a first load element is connected to the fifth end of the second scan line within the non-display area,

a second load element is connected to the sixth end of the third scan line within the non-display area, and

the first load element is not connected to the first scan line.

2. The display device according to claim 1 , wherein

each of the first load element and the second load element is a field-effect element.

3. The display device according to claim 1 , wherein

a length of the second scan line is shorter than a length of the first scan line, and

a length of the third scan line is shorter than a length of the second scan line.

4. The display device according to claim 3 , wherein

a fourth number of the field-effect elements is connected to the second scan line,

a fifth number of the field-effect elements is connected to the third scan line, the fourth number is smaller than the fifth number.
