It includes the first sub- lead 20311 and the second sub- lead 20312 positioned at different metal layer that adjacent first, which is fanned out to lead 2031, then
This second is fanned out to lead 2032 and may be considered and be made of the first sub- lead and the first sub- lead and above-mentioned first is fanned out to lead
The sub- lead 20311 of the first of 2031, which is located at different metal layer or above-mentioned second sub- lead 2032, may be considered by the second son
Lead forms and the second sub- lead and the above-mentioned first the second sub- lead 20312 for being fanned out to lead 2031 are located at different metal layer.
Those skilled in the art can be fanned out to lead 2032 for above-mentioned second and be arranged in the first metal layer according to the needs of actual conditions
Or second metal layer.For example, second be fanned out to lead 2032 can be set in the first metal layer and second metal layer resistivity compared with
Small metal layer.Specifically, it if the resistivity of above-mentioned the first metal layer is greater than the resistivity of second metal layer, and is fanned out to second
Lead 2032 it is adjacent first be fanned out to lead 2031 include positioned at the first metal layer the first sub- lead 20311 and be located at the second gold medal
Belong to the second sub- lead 20312 of layer, and this second is fanned out to lead 2032 and can be set in the lesser second metal layer of resistivity, this
When this second is fanned out to lead 2032 and the adjacent first the first sub- lead 20311 for being fanned out to lead 2031 is located at different metal layer,
It may be considered that this second be fanned out to lead be by with above-mentioned first to be fanned out to the first sub- lead 20311 of lead 2031 adjacent first
Sub- lead composition.This can enable any resistance value R1 for being fanned out to lead 203 and the resistance values for being fanned out to lead 203 adjacent thereto
R2 can satisfy -20%≤(R1-R2)/R2≤20%, reduces the resistance difference for being respectively fanned out to lead 203, improves display surface
The display effect of plate.
