The embodiment of the present invention provides a kind of flat field array base palte, and this flat field array base palte, including being arranged at substrate base
Data wire, grid line, pixel electrode and public electrode on plate, flat field array base palte also includes the first electrode and/or second
Electrode, and the first electrode is corresponding with the position of data wire, the second electrode is corresponding with the position of grid line.When this flat field array
When substrate is applied to the display device including liquid crystal layer, data wire and the first electrode can be not provided with lining at flat field array base palte
At the liquid crystal layer that the side of substrate, i.e. data wire are corresponding, formed vertical electric field with drive the liquid crystal molecule of this position towards
It is perpendicular on the direction of underlay substrate overturn；Grid line and the second electrode can form vertical electric field to drive at liquid crystal layer

And/or the liquid crystal molecule in the correspondence liquid crystal layer of grid line position overturns on the direction be perpendicular to underlay substrate, it is thus possible to
Enough stop the liquid crystal molecule generation one-way flow that the orientation of pixel electrode corresponding position is the most parallel with flat field array base palte, enter
And it is prevented from the phenomenon that liquid crystal molecule occurs one side to pile up.
On this basis, as it is shown in figure 1, when the first electrode 100 and/or the second electrode 200 are positioned at data wire 10 and grid line
The side of 20 away from substrate substrates 101, and the first electrode 10 and/or the second electrode 20 include multiple first strip sub-electrode 110
In the case of, relative to spacing H2 of adjacent second strip sub-electrode 120 and the ratio of the width W2 of the second strip sub-electrode 120
(H2/W2 is generally about 2) so that the electric field that pixel cell P correspondence position is formed in flat field array base palte 01 is with level
Electric field component is main, to ensure that the liquid crystal molecule 301 of this position revolves in the plane that flat field array base palte 01 is parallel
Turn, to show normally；Spacing H2 of adjacent second strip sub-electrode 120 and the width W2 of the second strip sub-electrode 120
Ratio need less than H2/W2, and the width W1 of the first strip sub-electrode 110 is less than or equal to the width of the second strip sub-electrode
W2, spacing H1 of adjacent first strip sub-electrode 110 is less than spacing H1 of adjacent second strip sub-electrode 110, so that putting down
The electric field that in field, face array base palte 01, data wire 10 and grid line 20 correspondence position are formed is based on ll vertical electric field component such that it is able to
Ensure that the liquid crystal molecule 301 of this position overturns in the vertical plane of flat field array base palte 01.
Concrete, when H1/W1 is more than 1:1, vertical electric field in the electric field that data wire 10 and grid line 20 correspondence position are formed
Component makes the liquid crystal molecule 301 of this position occur the angle overturn less on O-O ' direction, it is impossible to effectively prevent liquid
Brilliant molecule occurs one side to pile up.When H1/W1 is less than 1:2, on data wire 10 and grid line 20, adjacent first strip sub-electrode 110
Spacing H1 too small increase so that make required precision, and then make cost of manufacture increase, therefore, currently preferred,
In the case of flat field array base palte 01 includes the multiple second strip sub-electrodes 120 corresponding with pixel cell P position, first
The width W1 of strip sub-electrode 110 is less than or equal to the width W2 of the second strip sub-electrode, adjacent first strip sub-electrode 110
Spacing H1 is less than spacing H1 of adjacent second strip sub-electrode 110, spacing H1 of adjacent first strip sub-electrode 110 and Article 1
The ratio of the width W1 of shape sub-electrode 110 is between 1:2 to 1:1.
Such as, when the width W2 of the second strip sub-electrode 120 is 3 μm, spacing H2 of adjacent second strip sub-electrode 120 is
During 6 μm, i.e. H2/W2=2, can be 3 μm (i.e. W1=W2) by the width W1 of the first strip sub-electrode 110, adjacent first strip
Spacing H1 of sub-electrode 110 is 3 μm (H1 is less than H2), and now the ratio of H1/W1 is 1:1.
Further, for Simplified flowsheet, reduce cost of manufacture, by patterning processes just first electrode 100 and/
Or second electrode 200 arrange with material with layer with pixel electrode 50.Such as, such as Fig. 3 (Fig. 1 is along the sectional view in B-B ' direction) institute

20 with the same material of layer, uses metal material to make, so that the resistance of this public electrode wire 401 reduces, and then reduces aobvious
The load of showing device, reduces display picture simultaneously and the probability of the bad phenomenon such as image retention, film flicker occurs.
It is further preferred that the first electrode 100 is connected with public electrode wire 401, and it is connected with public electrode 40,
And/or, the second electrode 200 is connected with public electrode wire 401, and is connected with public electrode 40.
Such as, as shown in fig. 4 a, the first electrode 100 and the bulk electrode 300 of the second electrode 200 composition, simultaneously with public
Electrode wires 401 and public electrode 40 are connected, the most concrete connected mode, can as shown in Figure 4 b, this bulk electrode 300
In the second electrode 200 be connected with public electrode wire 401 by the first via D1, by the second via D2 and public electrode 40
It is connected, so so that bulk electrode 300 and public electrode wire 401 are extensive in the plane of flat field array base palte 01
In parallel such that it is able to further to reduce the resistance on public electrode wire 401, reduce the load of display device further, thus
Reduce display picture and the probability of the bad phenomenon such as image retention, film flicker occurs.
