Those second data wires 14b is not connected by the folding line a～d in connecting portion LT.It is noted that
The length of folding line a～d is that then length is longer further away from the first kink 23a.
With reference to Fig. 2, Fig. 3, corresponding to the Zhou Bianqu 12 of the second area 11B of non-rectangle viewing area 11,
Because common line 23, routing layer 25 and metal level 27 have taken certain range of distribution after impedance computation
Product, therefore it is less to be reserved to the arrangement space that electronic component 21 uses.Therefore, the present invention especially will be right
Mutual second spacing d2 of the second electronic component 21b that should be arranged in the second area 11B, setting becomes
Less than mutual first spacing d1 of the first electronic component 21a arranged corresponding to the first area 11A.For
In response to the diminution of spacing, the electronic component 21 that arranges corresponding to the second area 11B, such as second is electric
The connection of the second electronic component 21a in subcomponent group 18b, itself and the second data wire 14b is in response to institute
Need and have the folding line a～d in connecting portion LT as shown in Figure 3.It is of the invention to optimize based on above-mentioned
Layout, makes more flexible in layout designs.
Fig. 4 A and Fig. 4 B show the partial enlarged drawing of circuit near the second electronic component group 18 of Fig. 3,
To illustrate according to the configuration of electronic component 21 of the present invention, for the electrical performance of static discharge (ESD).
Reference picture 4A, when electrostatic discharge event ESD occurs in folding line b, static discharge current can
Can be towards path path1 and path2 flowing, if may destroy if most of flowing toward path path1
Sub-pixel SP that data wire 14 in viewing area 11 is connected inner member (such as thin film transistor (TFT),
Or other display elements etc.).Due to the first type of the invention and the second electronic component of Second-Type group 18a, 18b
Interior mutual second spacing d2 of the second electronic component 21b is less than the first spacing d1, the second electronic component
The electric capacity Xc to each other of the second electronic component 21b in group 18 become big so that electrical couplings effect compared with
By force, for the static discharge for belonging to high-frequency ac pattern, increase equivalent to the width by path path2.
Therefore, by the jump characteristic of static discharge, static discharge current can be divided to path path2 (as schemed
Shown in 4B), and reduce flowing to the static discharge current of path path1.
Fig. 5 shows the partial enlarged drawing of circuit near the second electronic component group 18 of Fig. 3, to say
The bright configuration according to electronic component 21 of the present invention, for the electrical performance of static discharge (ESD).
With reference to Fig. 5, it is considered to when static discharge in viewing area 11 outward (such as in the kink of common line 23
23a) the situation for occurring.Because impedance is directly proportional to line length, and electric current is inversely proportional to impedance, if path
The resistance difference of path1～path6 is bigger, then the allocation proportion difference of electric current is also bigger.Excessive electric current can
The electronic component 21b (such as diode) that can cause path path1 punctures conducting, and access path path1
Electric current can destroy data wire 14b connection sub-pixel SP inner member (for example thin film transistor (TFT) or
Other display elements etc.).Therefore, second in second electronic component of Second-Type of the present invention group 18b is electric
Mutual second spacing d2 of subcomponent 21b is less than the first spacing d1 so that the electronic component of Second-Type second
The second electronic component 21b in group 18b is positioned as close to, and static discharge stream is more fifty-fifty divided
The second electronic component 21b on each path path1～path6 is dissipated, the probability of destruction is reduced.
