Description
Technical field
The present invention relates to display technology field, more particularly to a kind of liquid crystal display panel and preparation method thereof.
Background technology
With the development of Display Technique, the plane such as liquid crystal display (Liquid Crystal Display, LCD) display dress
Put because having the advantages that high image quality, power saving, fuselage is thin and has a wide range of application, and be widely used in mobile phone, TV, individual number
The various consumption electronic products such as word assistant, digital camera, notebook computer, desktop computer, as the master in display device
Stream.
Liquid crystal display device on existing market is largely backlight liquid crystal display, it include liquid crystal display panel and
Backlight module (backlight module).The operation principle of liquid crystal display panel is put among the parallel glass substrate of two panels
Putting has many tiny electric wires vertically and horizontally in the middle of liquid crystal molecule, two panels glass substrate, liquid crystal is controlled by whether being powered
Molecular changes direction, generation picture is reflected by the light of backlight module.
Usual liquid crystal display panel is by color film (CF, Color Filter) substrate, thin film transistor (TFT) (TFT, Thin Film
Transistor) substrate, the liquid crystal (LC, Liquid Crystal) that is sandwiched between color membrane substrates and thin film transistor base plate and close
Sealing frame (Sealant) is constituted, and its moulding process is generally comprised：Leading portion array (Array) processing procedure (film, gold-tinted, etching and stripping
Film), stage casing is into box (Cell) processing procedure (TFT substrate and CF baseplate-laminatings) and back segment module group assembling processing procedure (driving IC and printing electricity
Road plate pressing).Wherein, leading portion Array processing procedures are mainly to form TFT substrate, in order to control the motion of liquid crystal molecule；Stage casing
Cell processing procedures mainly add liquid crystal between TFT substrate and CF substrates；Back segment module group assembling processing procedure is mainly driving IC pressings
With the integration of printed circuit board (PCB), and then drive liquid crystal molecule rotate, display image.
As industry pursues more reliable panel quality and more outstanding Consumer's Experience, LCD Display Techniques not section
Face challenge, and govern the development of technology the problem of broken bright spot always, how to efficiently reduce or prevent the appearance of broken bright spot
Great subject under discussion as lifting LCD quality.The generation overwhelming majority of broken bright spot is because TFT substrate and CF in current industry
After substrate is to group, sept (PS) is contacted with the alignment film (PI) on wherein side substrate, is rubbed in the presence of external force
Chip is produced, if these chips drop to open region and liquid crystal will be influenceed normally to deflect, broken bright spot (issue) is caused.Fig. 1 is existing
The structural representation of some liquid crystal display panels, from figure 1 it appears that after CF substrates 100 and 200 pairs of groups of TFT substrate, CF bases
Still there can be some spaces between sept 300 and TFT substrate 200 on plate 100, these spaces cause sept 300 to exist
Possess the space of slip under external force effect, the risk that broken bright spot is produced is added, as shown in Fig. 2 existing liquid crystal display panel
