Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention rather than limiting the invention.It also should be noted that in order to just
Only the parts related to the present invention are shown in description, attached drawing rather than entire infrastructure.
A kind of liquid crystal display substrate is present embodiments provided, which for example can be ito glass substrate,
It can be used as the component part of liquid crystal display panel, which for example can be flat liquid crystal display panel or 3D liquid
LCD panel.Fig. 2 is a kind of structural schematic diagram of liquid crystal display substrate provided in an embodiment of the present invention.As shown in Fig. 2, this reality
The liquid crystal display substrate 10 for applying example offer includes: substrate 11, and the alignment film 12 on substrate 11, and the alignment film 12 is at least
Cover the viewing area of liquid crystal display substrate 10.Wherein, alignment film 12 includes main body orientation area 121 and multiple extension areas 122, is extended
Area 122 is located at the corner in main body orientation area 121 and contacts with the turning in main body orientation area 121, the graphics shape of extension area 122
Different from the graphics shape in main body orientation area 121, and the extension area 122 is special-shaped figure.
It should be noted that 12 extension area of alignment film and main body are matched in liquid crystal display substrate 10 provided in an embodiment of the present invention
It is only exemplary as described in Figure 2 to the shape in area 11, in the case where satisfying the conditions as described above, liquid provided in an embodiment of the present invention
Brilliant display base plate can also be other forms, such as shown in Fig. 4~Fig. 6.
Refering to what is shown in Fig. 2, spraying alignment materials on the substrate 11 of liquid crystal display substrate 10 to form alignment film 12, this is matched
There are multiple extension areas 122 of 121 corner of main body orientation area 121 and main body orientation area to film 12.Due to liquid crystal display base
The alignment film 12 of plate 10 can control into the orientation of the liquid crystal molecule injected after box, thus the orientation formed is sprayed on substrate 11
The main body orientation area 121 of film 12 should at least cover the viewing area of liquid crystal display substrate 10, so that the liquid crystal molecule in viewing area
Orientation is controllable.Meanwhile the graphics shape of the extension area 122 of alignment film 12 is different from the graphics shape in main body orientation area 121, and prolongs
