DISPLAY PANEL
First Claim
1. A display panel comprising:
- a display area including a gate line and a data line; and
a gate driver connected to one end of the gate line, including a plurality of normal stages and dummy stages, integrated on a substrate to output a gate voltage,wherein a supplied scan start signal is transmitted through a first scan start signal wire and a second scan start signal wire,the first scan start signal wire transmits the scan start signal to a dummy stage of the dummy stages, andthe second scan start signal wire transmits the scan start signal to a first stage of the normal stages.

Abstract
The present invention divides a wire supplying a scan start signal to a gate driver into two wires, so as to avoid overlapping a clock signal line. In this way the clock signal is not delayed by interference, and a gate driving margin may continue uninterrupted, thereby uniformly outputting a gate-on voltage. In particular, if the clock signal line is connected to all stages in the gate driver and the clock signal line overlaps the scan start signal line, unsightly horizontal bands appear on the image and the parallel gate lines generate a very large parasitic capacitance. In contrast, the gate drivers in the present disclosure comprise clock signal lines which do not overlap the scan start signal lines. As benefits, interference resulting in horizontal banding is minimized and the power consumption may be reduced by about 10%.
