Description
Technical field:
The present invention is relevant for a kind of Liquid crystal disply device and its preparation method, particularly relevant for a kind of more Liquid crystal disply device and its preparation method of superior optical characteristics that provides.
Prior art:
Lcd technology is one of very popular in recent years technical field, and characteristics such as liquid crystal indicator has that volume is little, in light weight, power saving and full color have the potentiality that replace present cathode-ray tube display (CRT) greatly.
As shown in Figure 1, what show among the figure is typical liquid crystal indicator, comprises color filter (color filter) substrate 101, and array (array) substrate 102.Separate with splashing gap (ball spacer) 170 between colour filtering chip basic board 101 and the array base palte 102, in order to form thickness uniform cell gap (cell gap) 190.Be full of liquid crystal material 180 in the cell gap 190 between colour filtering chip basic board 101 and the array base palte 102, control the light throughput because of the characteristic that applies electric field and rotate by liquid crystal material.
As shown in Figure 2, what show among the figure is another kind of typical liquid crystal indicator, comprises colour filtering chip basic board 201, and array base palte 202.Separate with photoresistance formula gap (photo spacer) 260 between colour filtering chip basic board 201 and the array base palte 202, in order to form thickness uniform cell gap 290.Be full of liquid crystal material 280 in the cell gap 290 between colour filtering chip basic board 201 and array base palte 202, control the light throughput because of the characteristic that applies electric field and rotate by liquid crystal material.
What show among the figure as shown in Figure 3, is that tradition uses splashing gap and vacuum to suct the process flow diagram of the liquid crystal indicator of formula liquid crystal implantttion technique.After in step 30a and step 30b, forming colour filtering chip basic board and array base palte respectively, carry out the alignment film coating of step 31, that is be coated with alignment film respectively at above-mentioned two substrates.Then carry out orientation (rubbing) processing procedure of step 32.Secondly, carry out the formation fluid sealant of step 33 in the periphery of arbitrary substrate but reserve the fluid sealant coating process of an opening.After, step 34 forms splashing gap on array base palte.Then, colour filtering chip basic board and array base palte are carried out the upright processing procedure of group of step 35, carry out step 36 then, the cutting processing procedure that upright big glass substrate is cut into little face glass (panel) will be organized, utilize the vacuum technology of sucting to carry out the liquid crystal implantation step of step 37 subsequently, treat just to carry out the processing procedure that seals of step 38 after the liquid crystal injection fully, and the panel manufacturing process for cleaning of step 39, and finish the making of traditional liquid crystal indicator.The so-called formula liquid crystal implantttion technique that sucts, be meant several pieces of panels are placed in the container that is full of liquid crystal material, make inlet downward, put in the vacuum chamber after the heating, it is flooded in the liquid crystal storage tank, utilize capillarity and pressure differential liquid crystal to be injected a kind of liquid crystal implantttion technique in crack between the panel.
People such as Lim (U.S. Patent Publication No. 20040125319 A1) disclose a kind of Liquid crystal disply device and its preparation method, this device utilizes traditional vacuum to suct the technology filling liquid crystal, and improves at the uneven defective of the brightness that produces because of gravity (gravity mura).
In general, tradition forms gap of even cell gap in order to separate colour filtering chip basic board and array base palte, mostly be single kind of gap greatly, splashing gap that for example single use is shown in Figure 1, or single use photoresistance formula gap shown in Figure 2.But,, may cause panel when bearing external force, to produce light leak or uneven (the touch mura of contrast that causes display frame because of touching if only be used alone gap along with the increase of panel size; Be designated hereinafter simply as the touch-type defective), or cause display frame to produce light leak or the contrast inequality (is sound mura because of the vibrations of public address equipment; Be designated hereinafter simply as the vibration-type defective) etc. phenomenon.
