## 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

### Claim 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,
the first scan line, the second scan line and the third scan line are connected to the scanning circuit,
a number of all of the thin film transistors that are connected to the second scan line is smaller than a number of all of the thin film transistors that are connected to the first scan line,
a number of all of the thin film transistors that are connected to the third scan line is smaller than the number of all of the thin film transistors that are connected to the second scan line,
a first load element is connected to the second scan line within the non-display area,
a second load element is connected to the third scan line within the non-display area, and
the first load element is not connected to the first scan line.

### Claim 2 (depends on 1)

The display device according to claim 1, wherein
each of the first load element and the second load element is a field-effect element.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 3)

The display device according to claim 3, wherein
a number of the field-effect elements of the second load element is smaller than a number of the field-effect elements of the first load element.
