With the integration of printed circuit board, and then drive liquid crystal molecule rotation, show image.Wherein, under liquid crystal drop (LC Dispenser or
Person LC Inkjet) it is the important step that liquid crystal display panel makes, for forming liquid between TFT substrate and CF substrate
Crystal layer.Since there are mutual pollutions with uncured frame glue for liquid crystal, so needing to control the liquid of outermost when under liquid crystal drop
There is suitable distance, hypotelorism can pollute frame glue, or even puncture, and hypertelorism will lead to liquid between brilliant material and frame glue
Crystalline substance can not be diffused into the quadrangle of viewing area.
It is saved in (PI-Less) technology in alignment film, substrate surface need to increase additive without both alignment layers in liquid crystal
(Additive), which is diffused into the display area of substrate with the flowing of liquid crystal, and then by ultraviolet light, formation is matched
To layer.Because substrate surface is without alignment film, substrate surface poor diffusivity, as shown in Figure 1, using pattern under the liquid crystal drop of rectangle
100 (LC pattern) have the problem of additive cannot be diffused into the quadrangle of viewing area 200 well, cause quadrangle orientation different
Often, there is the exception that quadrangle light leakage whitens, it is bad in turn result in product.
Summary of the invention
The purpose of the present invention is to provide a kind of production methods of liquid crystal display panel, can effectively spread liquid crystal material
To entire viewing area, avoid showing bad.

Specific embodiment
Further to illustrate technological means and its effect adopted by the present invention, below in conjunction with preferred implementation of the invention
Example and its attached drawing are described in detail.
Referring to Fig. 6, the present invention provides a kind of production method of liquid crystal display panel, include the following steps:
Step S1, as shown in Fig. 2, providing first substrate 1, the first substrate 1 includes viewing area 11 and shows around described
Show the rim area 12 in area 11.
Preferably, the first substrate 1 be array substrate, which is provided with thin film transistor (TFT) array and with the film crystal
The pixel electrode that pipe array is electrically connected, 11 rectangle of viewing area, the rim area 12 is the square for surrounding the viewing area 11
Shape frame.
Step S2, frame glue 13 is coated in the rim area 12.
Preferably, the frame glue 13 is heat cure frame glue material, and the frame glue 13 is uncured frame glue at this time.
Step S3, area 111 under the liquid crystal drop being spaced with the rim area 12 is set in viewing area 11, and in the liquid crystal
It drips and instills liquid crystal material 14 in area 111；
Area 111 includes the first area 101 of rectangle and is connected respectively with the quadrangle of first area 101 under the liquid crystal drop
Four second areas 102.
Specifically, liquid crystal material is instilled in area 111 under the liquid crystal drop using machine under a liquid crystal drop in the step S3
14。
Further, it is to pass through modification that the method in area 111 under liquid crystal drop, which is arranged, in the step S3 in the viewing area 11
The control parameter of machine changes the shape in area 111 under the liquid crystal drop under liquid crystal drop.
Further, the liquid crystal material 14 in the step S3 is light alignment liquid crystal material, the smooth alignment liquid crystal material
Including liquid crystal molecule and light orientation additive, due to using light orientation, simultaneously alignment film is not formed in the first substrate 1,
The liquid crystal material 14 directly drips on first substrate 1 rather than drop is on alignment film.
It should be noted that the present invention increases the of protrusion by the quadrangle in the area under the liquid crystal drop of traditional rectangle
Two regions 102, can increase the liquid crystal material of the quadrangle liquid crystal drop Xia Qu, and guarantee liquid crystal material 14 can completely cover whole after spreading
A viewing area 11, display caused by avoiding because of 11 4 jiaos of viewing area without liquid crystal material covering is bad, promotes product yield.
Preferably, as shown in figure 3, in the first embodiment of the present invention, the shape of the second area 102 is rectangle,
The diagonal line of the diagonal line of the second area 102, the diagonal line of first area 101 and viewing area 11 is on same straight line.
Preferably, as shown in figure 4, in the second embodiment of the present invention, the shape of the second area 102 is Xiang Suoshu
The outside of first area 101 tip-angled shape outstanding, the center line of the wedge angle, the diagonal line of first area 101 and viewing area 11
Diagonal line be on same straight line.
Certainly, the shape of the second area 102 is not limited to this, and according to actual needs, the second area 102 may be used also
Think the other shapes such as semicircle shape or ellipticity.
It is noted that the purpose that the second area 102 is arranged is to help the covering of liquid crystal material 14 to display
The quadrangle in area 11, therefore the size of second area 102 needs to be determined according to the mobility of liquid crystal material 14, the liquid crystal material
Mobility is stronger, and the size of second area 102 is smaller, and needs to guarantee that second area 102 and uncured frame glue 13 are spaced,
It prevents from mutually polluting.
When it is implemented, second area 102 is only the region of an auxiliary diffusion, first area 101 is main liquid crystal drop
Lower region, thus the area of each second area 102 is much smaller than the area of first area 101.
Step S4, as shown in figure 5, providing the second substrate 2, by the second substrate 2 and 1 pair of composition box of first substrate.
Specifically, the second substrate 2 is color membrane substrates, is set to color filter film, black matrix" and public electrode thereon,
Liquid crystal is controlled by the voltage between public electrode and pixel electrode to rotate to different angle, realizes that picture is shown.
Further, the production method of the liquid crystal display panel further include:
Step S5, the frame glue 13 is toasted, so that the frame glue 13 solidifies.
Wherein, while the frame glue 13 solidifies, the baking also promotes the diffusion of liquid crystal material 14 to cover entire viewing area
11。
Further, the production method of the liquid crystal display panel further include:
Step S6, orientation is carried out to the liquid crystal material 14 using ultraviolet lighting, by the ultraviolet lighting light is matched
To additive reaction, so that liquid crystal molecule forms preset pre-tilt angle, LCD alignment is completed.
Further, in some embodiments of the invention, in orientation, it is also necessary in first substrate 1 and the second substrate 2
Upper application voltage, so that liquid crystal molecule is rotated to preset angle.
Specifically, the smooth orientation additive is a kind of phototaxis monomer.
In conclusion the present invention provides a kind of production method of liquid crystal display panel, include the following steps: step S1,
First substrate is provided, the first substrate includes viewing area and the rim area around the viewing area；Step S2, in the frame
Frame glue is coated in area；Step S3, area under the liquid crystal drop with the rim area interval is set in viewing area, and in the liquid crystal drop
Liquid crystal material is instilled in lower area；Area includes the first area of rectangle and is connected respectively with the quadrangle of first area under the liquid crystal drop
Four second areas；Step S4, the second substrate is provided, by the second substrate and first substrate to composition box, passes through change
The shape in area under liquid crystal drop increases second area in first area quadrangle, can guarantee that liquid crystal material effectively diffuses to viewing area
Quadrangle, avoid the quadrangle because of viewing area without liquid crystal material covering caused by show bad, promote product yield.
The above for those of ordinary skill in the art can according to the technique and scheme of the present invention and technology
Other various corresponding changes and modifications are made in design, and all these change and modification all should belong to the claims in the present invention
Protection scope.
