200 short side is obliquely extended in an angle.First electrode 210 is connected to each third branch electrode 230 with second electrode 220,
So that the level on entire pixel electrode 200 is consistent, to ensure that the deflection angle of liquid crystal in single pixel is consistent.In Fig. 1,
In the presence of the third branch electrode 230 for the different directions being distributed in four regions.Further, third branch electrode 230 is according to default
Distance interval setting.Third branch electrode 230 facilitates in Formation of liquid crystals pre-tilt angle, guides liquid crystal according to third branch electrode 230
Direction deflection, thus in one pixel formed four farmlands liquid crystal, to improve the display effect of picture.
Further, it is done if transversely being chosen on circuit substrate, changes the width of Non-overlapping Domain K1 in each point, obtain
The dark line result arrived is as shown in the table:
K1/μm | 2.32 | 2.75 | 2.82 | 3.01 | 3.04 | 3.14 | 3.21 | 3.93 | 4.34 | 4.92 |
Dark line | Have | Have | Have | Nothing | Nothing | Nothing | Nothing | Nothing | Nothing | Nothing |
