As shown in Figure 1B, 0.8≤a/b≤1.2 can be met apart from a and line width b, it is seen then that first in the present embodiment is fanned out to lead
10311 line width the distance between adjacent two oblique line portions 1 can be more or less the same with same metal level.In prior art
In, all in display panel are fanned out to lead and are generally arranged at same metal level, it is adjacent be fanned out to the distance between lead with
The line width difference for being fanned out to lead is also little, but adjacent first in the present embodiment is fanned out to lead 10311 and can be arranged on
Different metal level, therefore, in the first sub- fan-out area 1033 in sub- fan-out area 1031 and the 3rd, positioned at same metal level
First be fanned out to the quantity of lead 10311 reduce half and the adjacent first oblique line portion 1 for being fanned out to lead 10311 distance it is constant, this
Can cause positioned at each the first of same metal level be fanned out to the oblique line portion 1 of lead 10311 shared by D1 in the first direction away from
From reduction, so as to realize the distance for reducing the D1 in the first direction of lower frame area 1022 so that display panel 100 can be realized
Narrow frame design.And in the present embodiment, second, which is fanned out to lead 10321, is arranged at second metal layer M2, and second is fanned out to lead
10321 only include the line part parallel with first direction D1.Because the second fan-out line 10321 itself is parallel to first direction D1,
So its D1 in a first direction distance reached it is most narrow.
The display panel that above-described embodiment of the application is provided, driving chip 130 therein can be arranged on flexible circuit
On plate 120, flexible PCB 120 can be bundled in the lower frame area 1022 of array base palte 120, and fan-out area 103 is located at following
The first sub- fan-out area 1031, the second sub- fan-out area 1032, the 3rd sub- fanout area in frame area 1022, the fan-out area 103
It can be arranged in order in domain 1033 with D2 in a second direction, the first sub- fan-out area 1033 in sub- fan-out area 1031 and the 3rd can be set
There is a plurality of first to be fanned out to lead 10311, each first is fanned out to lead 10311, and D2 is arranged in order in a second direction, and in the first metal
It is arranged alternately in layer and second metal layer, so as to reduce the first sub- edge of fan-out area 1033 in sub- fan-out area 1031 and the 3rd
First direction D1 distance, you can to reduce the D1 in the first direction of lower frame area 1022 distance, display panel can be realized narrow
Frame design.
