As shown in fig. 6, line segment 421 and third class in second sub-segments 42, in first kind metal wire sections group L1
Line segment 423 in metal wire sections group is intervally arranged and head and the tail are sequentially connected.Line segment 421 extends along the first direction X, described
First direction X can be for by the direction of the first side a of the viewing area 33 direction second side c, the first side a and institute
It is opposite to state second side c.In the present embodiment, first direction X is perpendicular to first side a, that is, is parallel to viewing area 33
Third side b and four side d.Angle between the extending direction and first direction X of line segment 423 is the first angle.
It should be noted that in practical applications, the multiple line segment group can for three classes metal wire sections group or three classes with
On metal wire sections group.In one embodiment, the multiple line segment group can be first kind metal wire sections group L1, third metalloid
Line segment group (not shown) and the 4th metalloid line segment group (not shown).The extending direction of the first kind metal wire sections group L1 with
The extending direction of third metalloid line segment group intersects, and angle is the first angle, the extension of the first kind metal wire sections group L1
Direction is intersected with the extending direction of the 4th metalloid line segment group, and angle is the second angle.To avoid content redundancy, below with
It is illustrated for two sub-segments 42.
As shown in fig. 7, line segment 421, third eka-gold in second sub-segments 42, in first kind metal wire sections group L1
Belong to line segment 423 and the line segment 424 in the 4th metalloid line segment group in line segment group to be intervally arranged and be sequentially connected from beginning to end.
In one embodiment, as shown in figure 3, metal wire 34 can be arranged around the viewing area 33.Wherein, it can show
The metal wire 34 is arranged in first side a, second side c, the corresponding non-display area 32 of third side b in area 33.First side
A, second side c, multiple reciprocally bending section A can be respectively set in the corresponding non-display area 32 of third side b.Metal
Two endpoints 35,36 of line 34 can be located on the side of the four side d of the viewing area 33.
In embodiments of the present invention, as shown in Fig. 3~Fig. 4, the metal wire 34 includes multiple line segments；The multiple line segment
Between be sequentially connected in series.Specifically, metal wire 34 may include multiple reciprocally bending sections being sequentially connected in series, each reciprocally bending section
Interior line segment is also sequentially connected in series.In the present embodiment, not only metal line wire is simple, easily prepared, moreover, making crack detection
As a result simple, be conducive to the efficiency for improving crack detection, avoid the erroneous judgement introduced by testing result complexity.
In one embodiment, the material of the metal wire 34 can be molybdenum.When the metal wire prepared on a display panel
When material is molybdenum, since metal wire is easy to crack as display panel cracks, it is thus possible to improve crack detection
Accuracy.
In one embodiment, display panel 31 may include multilayer inorganic layer, and metal wire 34 may be provided at undermost nothing
On any side inorganic layer between machine layer and the inorganic layer of top layer.
In one embodiment, display panel 31 further include: driving chip (not shown).The driving chip includes high electricity
Two endpoints 35,36 of flat pin, the metal wire 34 are electrically connected with the high level pin.On the one hand, the endpoint of metal wire
After pin floating, due to antenna effect, the charge of surrounding can be attracted, damage by static electricity is caused to display panel；Therefore, metal wire
Endpoint is connected on the high level pin of driving chip, can prevent the charge product at the endpoint of metal wire to avoid antenna effect
It is tired to wound display panel.On the other hand, display panel is in the more complicated environment of various electric signals, and extraneous electric signal can be right
Electric signal in display panel generates interference.Therefore, after the endpoint of metal wire is connected on the high level pin of driving chip, outside
Boundary's electric signal, which encounters the constant pressure high level signal on metal wire, to be neutralized, and extraneous electric signal can be fused to constant pressure high level signal
In, the voltage of high level is presented, the circuit environment in display panel can become relatively quiet.So the endpoint of metal wire connects
After connecing on the high level pin of driving chip, relatively quiet hoop can be provided for electric signal corresponding in display panel
Border prevents external electric signal from interfering.
When detecting the crackle on above-mentioned display panel 31, display can be detected by detecting the resistance value of metal wire 34
It whether there is crackle on panel.It specifically, can be before being cut to display panel or carrying out reliability test, by two
Endpoint 35,36 is respectively connected to multimeter, the resistance value of metal wire 34 is detected, as reference resistance.It is carried out to display panel
After cutting or after carrying out reliability test, two endpoints 35,36 can be respectively connected to multimeter again, detect metal wire
34 resistance value, as test resistance value.When test resistance value is identical as reference resistance, indicate that there is no disconnected on metal wire
Crackle is not present on display panel for point.When test resistance value is bigger than reference resistance, and test resistance value and reference resistance
Difference is greater than preset threshold, but when being less than infinitely great, indicates that metal wire is not broken completely, there are fine cracks on display panel.
When test resistance value is infinitely great (for example test resistance value is 1M Ω), indicates that metal wire is broken completely, deposited on display panel
In crackle.
It should be noted that, although the number of reciprocally bending section A can be to be multiple, still, the tool of reciprocally bending section A
Body number also needs the detectable limit setting according to detection board, because if the number of reciprocally bending section A is excessive, can lead
It causes the resistance value of metal wire excessive, and then leads to the purpose that can not achieve crack detection, or cause testing result inaccurate.

In the present embodiment, since the non-display area setting in viewing area periphery includes the metal wire of reciprocally bending section, and
In reciprocally bending section, at least two extending direction in multiple line segments of metal wire intersects, in this way, metal can be improved
The probability that line is truncated by crackle, and then the probability for detecting crackle is improved, so as to efficiently detect to be on display panel
It is no that there are crackles.
Display device provided in an embodiment of the present invention can not only carry out crack detection in production or reliability test,
It is practical even if crack detection can also be carried out after forming product.
