With the angular bisector of second direction.Put down from fig. 6 it can be seen that frictional direction 3 ' is first direction 1 ' and the angle of second direction 2 '
Separated time, in the adjacent rows sub-pixel of the pixel unit, if friction direction occur deviation, or polarizer sheet sticking when
Time generation is crooked, and certain deflection can occur for the initial angle of the liquid crystal molecule above sub-pixel area, because the first sub-pixel area
The incline direction of middle RGB is identical with the incline direction of the RGB in the 3rd sub-pixel area respectively, so above the 3rd sub-pixel area
The initial angle of liquid crystal molecule is identical with the initial angle of the liquid crystal molecule above the first sub-pixel area；In second sub-pixel area
The incline direction of RGB is identical with the incline direction of the RGB in the 4th sub-pixel area respectively, then the liquid crystal above the second sub-pixel area

Occur crooked when polarizer sheet sticking, and cause the initial angle of liquid crystal molecule and the second row picture above the first row sub-pixel
The initial angle of plain top liquid crystal molecule is different, then the first row is bright, and the second row is dark, or the first row is dark, and the second row is bright, causes
The band phenomenon descended two row brightness unevenness and occurred.
In the present invention, strip shaped electric poles are included in sub-pixel, then sub-pixel includes at least one slit (slit), it is assumed that
There is n slit in each sub-pixel, the line width of slit is A, and the line width of strip shaped electric poles is B, it is assumed that slit's to pixel edge must
To be L apart from the width for C, wherein C >=2 μm, whole sub-pixel, then if the width of sub-pixel is just 2C+nA+ (n+1) B
(top com structures), or during 2C+nA+ (n-1) B (mid com structures), the distribution of its slit line width line-spacing is most rational.Figure
7a is the structure diagram of the sub-pixel provided in the embodiment of the present invention one, it can be seen from fig 7a that sub-pixel is to tilt to set
Put, so the line width B of the line width A of line width L, slit of sub-pixel and strip shaped electric poles will be with next with the perpendicular direction of slit 6
Determining, slit 6 is parallel with first direction 1 ', and first straight line 7 and first direction 1 ' are perpendicular, so the line width L of sub-pixel,
The line width A of the slit and line width B of strip shaped electric poles is the width on 7 direction of first straight line.
Usually when carrying out dot structure design, due to the limitation of technological ability, the line width and line-spacing of pixel slit slit
All it is that size limits, under normal circumstances, strip shaped electric poles and slit and the width of pixel meet L=2C+nA+ (n-1) B or L
=2C+nA+ (n+1) B；If the width of pixel is bigger than 2C+nA+ (n+1) B or 2C+nA+ (n-1) B slightly, but is not enough to put
The line width of next group of new slit line widths and strip shaped electric poles, then slit distribution is just no longer rationally, that is, the width when sub-pixel
When degree L is less than 2C+ (n+1) A+nB more than 2C+nA+ (n-1) B, or L is less than 2C+ (n+1) A+ (n+ more than 2C+nA+ (n+1) B
2) during B, it will usually widen slit line widths or widen slit line-spacings；But if run into the specific pixel in part, such as
The pixel of 5.5 cun of HD resolution ratio, slit line widths are simply widened or widen slit line-spacings, just occur serious black
Farmland, so as to cause the situation that aperture opening ratio rises but transmitance is not risen accordingly.
In the dot structure design of the present invention, slit line widths are not widened or widen slit line-spacings, but by picture
Plain electrode is designed also according to the relation of L=2C+nA+ (n-1) B or L=2C+nA+ (n+1) B, compared with prior art
It is to be compressed sub-pixel, and each sub-pixel is compressed in rear additional part region, that is, the present invention and carries
The first area arrived, the first area corresponds to the second area on second substrate, and second area is then used for setting black square
Battle array BM, and insulated column can be arranged on second area；And if to set insulated column in second area, need using extremely
Few 3 sub-pixels are compressed, and the region out so compressed could be used for setting insulated column enough；In the prior art,
Usually when insulated column is set, BM will be made big, can thus reduce the aperture opening ratio of panel, and then influence the aobvious of panel
Show effect.And in the present invention, insulated column is arranged on second area, then will not reduce the aperture opening ratio of panel, additionally it is possible to is improved
The display effect of panel.
In the present invention, 3 sub-pixels are included in four sub-pixel areas respectively, each sub-pixel includes at least one
A slit 6 and a strip shaped electric poles 1, strip shaped electric poles 1 are parallel to first direction 1', and each sub-pixel includes four edges, its
In two sides it is parallel with x-axis direction, two other side is parallel with first direction 1', as shown in Figure 7b, have orthogonal x-axis and
Y-axis, x-axis are horizontally oriented, and y-axis is vertical direction, which is a rectangle, as can be seen that the rectangle from Fig. 7 b
Four vertex be A ', B ', C ', D ', in rectangle A ' B ' C ' D ', line segment A ' B ' and C ' D ' are parallel with y-axis, line segment A ' D '
And B ' C ' are parallel with x-axis, the length of the rectangle is that the length of line segment A ' B ' and C ' D ', line segment A ' B ' are the lines of the sub-pixel area
Wide P；Perpendicular straight line is first straight line 7 with first direction 1', and first straight line 7 passes through the vertex A' of the sub-pixel area, with this
The intersect at a point angles of E ', line segment A ' E ' and line segment A ' B ' of the side B ' C ' of sub-pixel area are θ, and the length of line segment A ' E ' is P ',
Then the relation between P ' and P is P '=P (θ)=P/cos (θ).
With reference to figure 2, as described above, first area 2 is identical with the size of second area 4, so in second area 4 BM it is big
It is small to be weighed by the size of first area 2；Because the sub-pixel area sub-pixel is obliquely installed, sub-pixel
Line width and the line width of BM will be determined with the direction perpendicular with slit 6, so the line width of sub-pixel and the line width of BM are all
Width on one straight line, 7 direction.BM will be set between adjacent subpixels, as can be seen that the line of the sub-pixel from Fig. 7 b
Width is L, and the width of the black matrix BM between two neighboring sub-pixel is M, and the width of BM is d in the second area, and d=d '
+ d ", and the width of the BM in second area includes the BM between the adjacent sub-pixel in left and right, thus pass through compression in the present invention
Sub-pixel and the part width that is available is that the width of second area subtracts the width of the BM set between two adjacent subpixels
Degree, can find out, d ' includes two parts width, and a part of width is the width of the BM between two neighboring sub-pixel from Fig. 7 b
M, a part of width is a part of width for compressing the region that sub-pixel is available, thus three sub-pixels of actual compression are vacated
The width in region come is d-M, and the width in the region that three sub-pixels compressions are available refer to be not enough to put down three groups it is new
The line width of slit line widths and strip shaped electric poles, then 0 ＜ d-M ＜ 3 (A+B)；When panel design is actually carried out, due to technique energy
The limitation of power, the size of the width M of the black matrix BM between two neighboring sub-pixel are greater than equal to 5 μm, and less than or equal to 6
μm。
In conclusion and combine Fig. 7 a, P, P ', L, M, d meet following relational expression：
P '=P (θ)=3L+2M+d,
Wherein d=d '+d ", 5 μm≤M≤6 μm；
And L=2C+nA+ (n-1) B or L=2C+nA+ (n+1) B；
It can then draw the pass between the width B of strip shaped electric poles and the width A of slit in the width P and sub-pixel of sub-pixel area
It is formula, it is as follows：
P (θ)=3 [2C+nA+ (n-1) B]+2M+d,
0 μm of wherein 0 μm of A ＞, B ＞, C >=2 μm, 5 μm≤M≤6 μm, 0 ＜ d-M ＜ 3 (A+B)；
Or P (θ)=3 [2C+nA+ (n+1) B]+2M+d,
0 μm of wherein 0 μm of A ＞, B ＞, C >=2 μm, 5 μm≤M≤6 μm, 0 ＜ d-M ＜ 3 (A+B)；
Pixel is compressed using the above method, in the case where panel aperture opening ratio will not be reduced, additionally it is possible to realize wide
