Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not paying creative work, all belongs to the scope of protection of the invention.
Embodiments provide a kind of array base palte, comprise public electrode and pixel electrode, among public electrode and pixel electrode, one is reticulate texture, and another is platy structure.
When applying voltage between public electrode and pixel electrode, liquid crystal molecule can deflect along moving towards in cancellated electrode.Cancellated each grid is a polygon, liquid crystal molecule corresponding to polygonal every bar limit, will deflect along the direction on this limit, liquid crystal molecule corresponding to each limit just forms the dot structure of multidomain, so user is identical from the image that the direction on every bar limit is watched, thus solve existing liquid crystal panel because the direction of liquid crystal deflecting element is single, cause the technical matters that the viewing angle symmetry of liquid crystal display is poor.
Embodiment 1:
The array base palte that the embodiment of the present invention provides, public electrode is reticulate texture, and pixel electrode is platy structure.Certainly, also public electrode can be made platy structure, pixel electrode is made reticulate texture, its technique effect is identical.
In the embodiment of the present invention, cancellated grid is regular polygon.Each angle, each limit of regular polygon is all equal, inherently has symmetric shape, so liquid crystal molecule is according to the deflection of such multidomain form, the display effect of liquid crystal display can be made to have better symmetry.
As depicted in figs. 1 and 2, in the embodiment of the present invention, cancellated grid is regular hexagon.When applying voltage between public electrode 11 and pixel electrode 2, liquid crystal molecule can along six kinds of symmetrical direction deflections, because orthohexagonal opposite side is parallel, so the yawing moment of liquid crystal molecule has three kinds, namely define the dot structure on three symmetrical farmlands, and each farmland is dimeric, the deflection schematic diagram of liquid crystal molecule as shown in Figure 3, such liquid crystal display is just provided with extraordinary viewing angle symmetry, and the contrast simulation drawing of different visual angles as shown in Figure 4.
As shown in Figure 5, in the embodiment of the present invention, public electrode 11 covers (over lap) on the data line 3 of array base palte.Like this, the public electrode 11 of whole array base palte can be made into an entirety, make the Design and manufacture process of electrode pattern more simple.
