Embodiment
Below, the disclosure is discussed in detail in conjunction with specific embodiments.
In an embodiment of the disclosure, as shown in Figure 1a, liquid crystal display panel 100 includes first substrate 11, the second base
Plate 12 and the liquid crystal layer 15 being arranged between the first substrate 11, second substrate 12, frame glue 160.Wherein, the frame glue
160 are set around the liquid crystal layer 15, for bonding the first substrate 11, second substrate 12 while by the liquid crystal layer
15 are closed in the sealing space 151 enclosed by the frame glue 160 and the first substrate 11, second substrate 12.In order to
Holding power between first substrate 11 and second substrate 12 is provided, sept 170 has been additionally provided with the sealing space 151.
The projection on first substrate 11 or second substrate 12 respectively of liquid crystal layer 15, may be defined as liquid crystal display panel
Viewing area 111, the region around viewing area 111 may be defined as non-display area 112.Usually, liquid crystal layer 15 is arranged on described aobvious
Show in area 111, viewing area 111 in response to liquid crystal layer 15 shape and usually from rectangle.
It is to mark off frame glue material coating area (in figure in non-display area 112 in advance in a kind of existing frame glue manufacture craft
Do not show), frame glue material can be selected to coat on first substrate 11 or second substrate 12, and one is formed around the viewing area 111
The figure of closing., can be in filling liquid crystal molecule in the viewing area 111 that frame glue material is encircled a city before treating that frame glue material parches.Then, institute
First substrate 11, second substrate 12 are stated into box processing procedure, makes the first substrate 11, the exactitude position of second substrate 12, sets
The first substrate 11 (or second substrate 12) of framed sizing material and liquid crystal molecule is corresponding to fit in (or the first substrate of second substrate 12
11).So after frame glue material solidification, first substrate 11 and second substrate 12 bond, by substrate cut process by first
Substrate, second substrate are LCD Slab element independent one by one along substrate cut wire cutting.Because this technique needs
Filling liquid crystal molecule is just needed before frame glue material is uncured, liquid crystal molecule is likely to contact with frame glue material concurrently biochemical anti-
Answer, influence the quality of follow-up display.Therefore, it is necessary to spacer portion is set between the coating area of frame glue material and liquid crystal molecule
The chance that part, barrier or reduction liquid crystal contact with frame glue, improves product qualification rate.
Wherein, the first substrate 11 can be active switching array substrate, for example, thin-film transistor array base-plate
(tft array substrate).Specifically, thin film transistor (TFT) array (not shown) is provided with the first substrate 11, it is described thin
Film transistor array (does not show including forming active electrode (not shown), drain electrode (not shown) and gate electrode in figure
Go out), and/or scan line (not shown), the metal level 113 of data wire (not shown).
Second substrate 12 may be, for example, colored optical filtering substrates (CF substrate).Wherein, it is provided with the second substrate 12 black
Color matrix layer 121, photoresist layer (not shown) and the transparent electrode layer 122 being covered in the black-matrix layer 121.
Transparent electrode layer 122 described in the covering part of frame glue 160.
Wherein, as shown in Fig. 1 b, Fig. 1 c, on the non-display area 112 of the first substrate 11 frame glue 160 is preset out to apply
Region is covered, corresponding to the coating zone of frame glue 160, the first limiting section 14 is set on the metal level 113.First limit
Position portion 14 is set along the non-display area 112 in banding or strip, for the spacing of frame glue 160；So that the frame glue 160 applies
Overlay on first limiting section 14 and be then not easy to leak outside.
Specifically, with reference to shown in Fig. 1 a, Fig. 1 c, first limiting section 14 of the present embodiment comprises at least：First barrier wall
141st, the second barrier wall 142.First barrier wall 141 is set close to the viewing area 111, and pre- with the viewing area 111
Provided with a safe distance.The safe distance is able to ensure that frame glue 160 will not mutually pollute with liquid crystal layer.Second barrier wall 142 is set
It is placed in the outside of first barrier wall 141 (i.e. between the first barrier wall 141 and substrate cut line) so that the first barrier wall
141st, the second barrier wall 142 is set away from the liquid crystal layer successively.Deposited between first barrier wall 141, the second barrier wall 142
It is used to house the first guide groove 144 of the frame glue 160 to form one in the first spacing.
Alternatively, in actual production, after frame glue material is cured as frame glue 160, the expansion rate of volume up to 250%~
280%；And when first substrate 11, second substrate press about 12, frame glue material can also spread towards the both sides of the first limiting section 14.Treat
After frame glue material solidifying and setting is referred to as frame glue 160, now the wide cut of frame glue 160 is defined as line width d.In the present embodiment, with reference to Fig. 1 c
The wide cut in predeterminable first gap is D1, i.e., the width of described first guide groove 144 is D1.And the line width d's of frame glue 160 is big
The no quality accurately to liquid crystal display panel quality is that have an impact to subtotal at last, therefore the expansion of frame glue 160 or diffusion amplitude are equal
It can be taken into account in after the final shaping in the line width values of frame glue 160.If the line width of frame glue 160 is too thin, follow-up contraposition pressure is likely to result in
Close processing procedure vent sequence is bad, liquid crystal can not fill complete, the bad phenomenon of panel gap uniformity, the periphery of frame glue 160 occurs
The bad phenomenons such as white edge.If the line width of frame glue 160 is too thick, the difficulty of follow-up cutting processing procedure may be increased as because being applied to alignment film
On cause frame glue 160 to peel off, frame glue 160 is too close to viewing area 111 and causes pollution problem between liquid crystal etc..
It is preferred that the wide cut D1 of the first guide groove 144 is preferred not less than the line width d of frame glue 160, as illustrated in figure 1 c.Such as
This, in the coating of frame glue material, can make frame glue material be coated between the first barrier wall 141, the second barrier wall 142, even in
In subsequent step by substrate pressing, the process of setting expansion still can ensure that most of frame glue 160 fall into the first barrier wall 141,
In the first guide groove 144 that second barrier wall 142 is formed.Internally, the first barrier wall 141 can prevent frame glue 160 and liquid crystal
Mutual pollution, externally, the second barrier wall 142 can prevent that the line width of frame glue 160 is excessive, effectively define the position of frame glue 160
And shape.
Further, the liquid crystal display panel of different sizes or model, its viewing area 111, the area of non-display area 112
It is different.Made to adapt to the frame glue 160 of the liquid crystal display panel of different sizes or model, the first of the present embodiment is spacing
Portion 14 also includes the 3rd barrier wall 143, as described in Fig. 1 d.3rd barrier wall 143 is arranged at outside second barrier wall 142
Side, i.e., between the second barrier wall 142 and substrate cut line.Have the between 3rd barrier wall 143, the second barrier wall 142
Two space Ds 2 are used for the second guide groove 145 for housing the frame glue 160 with formation.The introducing of second guide groove 145 can meet
The requirement that the line width of frame glue 160 can be adjusted flexibly.For example, large-sized liquid crystal display panel needs the appropriate increase line of frame glue 160
Width is to keep the rock-steady structure of substrate, and now, frame glue material can be coated in the first guide groove 144, the second guide groove 145, with
Larger line width is obtained, and similarly, the first barrier wall 141, the 3rd barrier wall 143 can be equally played to the spacing of frame glue 160
Effect.Similarly, now the preferably width D 1 of first guide groove 144 is more than with the sum of width D 2 of the second guide groove 145
The frame glue line width d.
Alternatively, it is primary, therefore the height of the first barrier wall 141 to prevent contact of the uncured frame glue 160 with liquid crystal
Degree needs appropriate increase.For example, the height h of the first barrier wall 141 should be less than first substrate, second substrate to box press after away from
From H, and preferred h>H/2 is preferred.Second barrier wall 142, the 3rd barrier wall 143 height can relative reduction, to meet frame glue
160 expansion needs；For example, it may be the height of the second barrier wall 142, the 3rd barrier wall 143 is less than the first barrier wall 141
Highly, it is highly identical between the second barrier wall 142, the 3rd barrier wall 143；In another example can be first barrier wall 141,
Second barrier wall 142, the height of the 3rd barrier wall 143 are reduced (with reference to shown in figure 1a) successively.
Further, in order that the expansion process of frame glue 160 is more steady, make frame glue 160 and the bonding of substrate even closer
Reliably, the present embodiment is further adjusted to the structure of the first limiting section 14.
As shown in fig. le, first barrier wall 141 can be continuous bar, can also be split as the continuous block in portion
Body.For example, first barrier wall 141, the second barrier wall 142 can be split as some groups of the first successive stoppers of head and the tail
Gap w be present between 141A, the second stopper 142A, the first stopper 141A, between the second stopper 142A.Will
First barrier wall 141, the second stopper 142A " from integralization zero ", are on the one hand the first barrier wall 141, the second barrier wall 142
Expand with heat and contract with cold and flow down enough spaces, and save cost；On the other hand the first barrier wall, the second barrier wall are considerably increased
Contact area between 142 and frame glue so that the concatenation ability increase between the first limiting section 14 and frame glue 160.In consideration of it, the
Gap between one stopper 141A, between the second barrier wall 142 can be with identical, can also be different.
Alternatively, as shown in Figure 1 f, can also select so that the first barrier wall 141 keeps continuous strip to form a closing
Figure, with most effective contact of the isolation liquid crystal molecule with frame glue, and can make the second barrier wall 142 be broken as several the
Gap between two stopper 142A, the second stopper 142A, which awards frame glue 160, to be had toward line of cut expansion sufficient space,
Add the contact area between the second barrier wall and frame glue.
Similarly, with reference to shown in Fig. 1 e, Fig. 1 f, it is successive that the 3rd barrier wall 143 can also be split as some groups of head and the tail
The 3rd stopper 143A, gap w be present between the 3rd stopper 143A.So that painting of the frame glue 160 in the first stop part
It is covered with more regulation spaces.Gap w between second stopper 142A (the 3rd stopper 143A) can be with identical, can also not
Together, but it is not more than first spacing.
Certainly, the position between the first stopper 141A, the second stopper 142A, the 3rd stopper 143A is unrestricted, can
, can also mutual dislocation neatly to correspond to.
Gap between first substrate 130, second substrate 140 is supported in order to stable, can also be mixed in the sealing space
Some septs 170, there is provided the support force of upper and lower two-layer substrate.Wherein, sept 170 can be spherical shape or column, material
It may be, for example, metal or resin, the metal layer in first substrate can be formed by photoetching technique.Further, at least one
The individual sept 170 is arranged between the liquid crystal layer 150 and the frame glue 160 (with reference to shown in figure 1b), sept 170
The highly preferred gap between first substrate 130, second substrate 140 is identical.Such sept 170 can be noted in liquid crystal molecule
Chance fashionable, that effectively barrier or reduction liquid crystal molecule contact with frame glue, reduces the probability that liquid crystal molecule reacts with frame glue,
Improve product qualification rate.
The present embodiment also provides the preparation side of this thin film transistor base plate (TFT substrate) with the limiting section of frame glue 160

31).So after frame glue material solidification, first substrate 31 and second substrate 32 bond, by substrate cut process by first
Substrate, second substrate are LCD Slab element independent one by one along substrate cut wire cutting.Because this technique needs
Filling liquid crystal molecule is just needed before frame glue material is uncured, liquid crystal molecule is likely to contact with frame glue material concurrently biochemical anti-
Answer, influence the quality of follow-up display.Therefore, it is necessary to spacer portion is set between the coating area of frame glue material and liquid crystal molecule
The chance that part, barrier or reduction liquid crystal contact with frame glue, improves product qualification rate.
Wherein, the first substrate 31 can be active switching array substrate, for example, thin-film transistor array base-plate
(tft array substrate).Specifically, thin film transistor (TFT) array (not shown) is provided with the first substrate 31, it is described thin
Film transistor array (does not show including forming active electrode (not shown), drain electrode (not shown) and gate electrode in figure
Go out) metal level 134.
Second substrate 32 may be, for example, colored optical filtering substrates (CF substrate).Wherein, it is provided with the second substrate 32 black
Color matrix layer 321, photoresist layer (not shown) and the transparent electrode layer 322 being covered in the black-matrix layer 221.
Transparent electrode layer 322 described in the covering part of frame glue 360.
Wherein, with reference to shown in Fig. 3 b, the coating area of frame glue 360 is preset out on the non-display area 312 of second substrate 32
Domain, corresponding to the coating zone of frame glue 360, the second limiting section 34 is set in the black-matrix layer 321.Second limit
Position portion 34 is used for the spacing of frame glue 360, and the frame glue 360 is limited in around viewing area 311.
Specifically, with reference to shown in Fig. 3 a, Fig. 3 c, second limiting section 34 of the present embodiment comprises at least：4th barrier wall
341st, the 5th barrier wall 342.4th barrier wall 341 is set close to the viewing area 311, and pre- with the viewing area 311
Provided with a safe distance.The safe distance is able to ensure that frame glue 360 will not mutually pollute with liquid crystal layer.4th barrier wall 341,
Five barrier walls 342 are set away from the liquid crystal layer successively.Spacing be present between 4th barrier wall 341, the 5th barrier wall 342
D3 is used to house the 3rd guide groove 344 of the frame glue 360 to form one.
Alternatively, in actual production, after frame glue material is cured as frame glue 360, the expansion rate of volume up to 250%~
280%；And when first substrate 31, second substrate press about 32, frame glue material can also spread towards the both sides of the second limiting section 34.Treat
After frame glue material solidifying and setting is referred to as frame glue 360, now the wide cut of frame glue 360 is defined as line width d.In the present embodiment, with reference to Fig. 3 c
The wide cut in predeterminable first gap is D1, i.e., the width of described 3rd guide groove 344 is D1.And the line width d's of frame glue 360 is big
The no quality accurately to liquid crystal display panel quality is that have an impact to subtotal at last, therefore the expansion of frame glue 360 or diffusion amplitude are equal
It can be taken into account in after the final shaping in the line width values of frame glue 360.If the line width of frame glue 360 is too thin, follow-up contraposition pressure is likely to result in
Close processing procedure vent sequence is bad, liquid crystal can not fill complete, the bad phenomenon of panel gap uniformity, the periphery of frame glue 360 occurs
The bad phenomenons such as white edge.If the line width of frame glue 360 is too thick, the difficulty of follow-up cutting processing procedure may be increased as because being applied to alignment film
On cause frame glue 360 to peel off, frame glue 360 is too close to viewing area 311 and causes pollution problem between liquid crystal etc..
Similarly, Fig. 3 c can be combined to understand, also, it is preferred that the wide cut D1 of the 3rd guide groove 344 is not less than the frame glue
360 line width d are preferred.In this way, in the coating of frame glue material, frame glue material can be made coated in the 4th barrier wall 341, the 5th barrier wall
Between 342, it still can ensure that most of frame glue 360 is fallen into by substrate pressing, the process of setting expansion in subsequent step
In the 3rd guide groove 344 that 4th barrier wall 341, the 5th barrier wall 342 are formed.Internally, the 4th barrier wall 341 can prevent
Frame glue 360 and the mutual pollution of liquid crystal, externally, the 4th barrier wall 341 can prevent that the line width of frame glue 360 is excessive, effectively define
The location and shape of frame glue 360.
Further, the liquid crystal display panel of different sizes or model, its viewing area 311, the area of non-display area 312
It is different.Made to adapt to the frame glue 360 of the liquid crystal display panel of different sizes or model, as shown in Figure 3 d, this implementation
Second limiting section 34 of example also includes the 6th barrier wall 343.6th barrier wall 343 is arranged at the 5th barrier wall 342
Outside, i.e., between the 5th barrier wall 342 and substrate cut line.Exist between 6th barrier wall 343, the 5th barrier wall 342
4th space D 4 is used for the 4th guide groove 345 for housing the frame glue 360 with formation.The introducing of 4th guide groove 345 can expire
The requirement that the sufficient line width of frame glue 360 can be adjusted flexibly.For example, large-sized liquid crystal display panel needs appropriate increase frame glue 360
Line width is to keep the rock-steady structure of substrate, and now, frame glue material can be coated in the 3rd guide groove 344, the 4th guide groove 345,
To obtain larger line width, and similarly, the 4th barrier wall 341, the 6th barrier wall 343 can equally play the limit to frame glue 360
Position effect.Similarly, now preferably the width D 3 of the 3rd guide groove 344 and the sum of width D 4 of the 4th guide groove 345 are big
In the frame glue line width d.
Alternatively, it is primary, therefore the height of the 4th barrier wall 341 to prevent contact of the uncured frame glue 360 with liquid crystal
Degree needs appropriate increase.For example, the height h of the 4th barrier wall 341 should be less than first substrate, second substrate to box press after away from
From H, and preferred h>H/2 is preferred.5th barrier wall 342, the 6th barrier wall 343 height can relative reduction, to meet frame glue
360 expansion needs；For example, it may be the height of the 5th barrier wall 342, the 6th barrier wall 343 is less than the 4th barrier wall 341
Highly, it is highly identical between the 5th barrier wall 342, the 6th barrier wall 343；In another example can be the 4th barrier wall 341,
5th barrier wall 342, the height of the 6th barrier wall 343 are reduced (with reference to figure 3a) successively.
Further, in order that the expansion process of frame glue 360 is more steady, the structure of frame glue 360 of formation is more reliable, this implementation
Example is further adjusted to the structure of the second limiting section 34.
4th barrier wall 341, the 5th barrier wall 342 can be continuous bars, and it is continuous can also to be split as portion
Block.For example, as shown in Figure 3 e, the 4th barrier wall 341, the 5th barrier wall 342 can be split as some groups of head and the tail phases
After the 4th stopper 341A, the 5th stopper 342A, between the 4th stopper 341A, the 5th stopper 342A it
Between gap w be present.By the 4th barrier wall 341, the 5th barrier wall 342 " be on the one hand the 4th barrier wall 341 from integralization zero ",
Expanding with heat and contract with cold for five barrier walls 342 flows down enough spaces, and saves cost；On the other hand the 4th barrier wall is considerably increased
341st, the contact area between the 5th barrier wall 342 and frame glue so that the concatenation ability between the first limiting section 34 and frame glue 360
Increase.In consideration of it, the gap between the 4th stopper 341A, the 5th stopper 342A can be with identical, can also be different.
Similarly, alternatively, as illustrated in figure 3f, can also select so that the 4th barrier wall 341 keeps continuous strip-like-shaped
Into the figure of a closing, with contact of the most effective isolation liquid crystal molecule with frame glue, and if the 5th barrier wall 342 can be made to be broken as
Gap between dry the 5th stopper 342A, the 5th stopper 342A, which awards frame glue 360, has past line of cut expansion empty enough
Between, also increase the contact area between the second barrier wall and frame glue.
Similarly, as shown in Fig. 3 e, Fig. 3 f, the 6th barrier wall 343 is split as the 6th successive resistance of some groups of head and the tail
Gap w be present between block 343A, the 6th stopper 343A.So that frame glue 360 is more in being coated with for the second stop part
Adjust space.Gap w between 5th stopper 342A (the 6th stopper 343A) can be with identical, can also be different, but less
In the D4.
Certainly, the position between the 4th stopper 341A, the 5th stopper 342A, the 6th stopper 343A is unrestricted, can
, can also mutual dislocation neatly to correspond to.
Gap between first substrate 31, second substrate 32 is supported in order to stable, one can be also mixed in the sealing space
A little septs 370, there is provided the support force of upper and lower two-layer substrate.Wherein, sept 370 can be spherical shape or column, and material can
For example, metal or resin, it can be formed by photoetching technique above the black-matrix layer 321 of second substrate 32.Further
Ground, at least one sept 370 are arranged between the liquid crystal layer 350 and the frame glue 360 (with reference to shown in figure 3b), such as
This sept 370 effectively can obstruct or reduce the chance that liquid crystal molecule contacts with frame glue when liquid crystal molecule injects, and reduce liquid
The probability that brilliant molecule reacts with frame glue, improve product qualification rate.

Structure, now, frame glue material can be coated in the 3rd guide groove 584, the 4th guide groove 585, to obtain larger line width, and equally
Ground, the 4th barrier wall 581, the 6th barrier wall 583 can equally play the position-limiting action to frame glue 560.Similarly, now preferred institute
State the wide cut of the 3rd guide groove 584 and be more than the frame glue line width d with the wide cut sum of the 4th guide groove 585.
Alternatively, it is primary, therefore the height of the 4th barrier wall 581 to prevent contact of the uncured frame glue 560 with liquid crystal
Degree needs appropriate increase.For example, the height h of the 4th barrier wall 581 should be less than first substrate, second substrate to box press after away from
From H, and preferred h>H/2 is preferred.5th barrier wall 582, the 6th barrier wall 583 height can relative reduction, to meet frame glue
560 expansion needs；For example, it may be the height of the 5th barrier wall 582, the 6th barrier wall 583 is less than the 4th barrier wall 581
Highly, it is highly identical between the 5th barrier wall 582, the 6th barrier wall 583；In another example can be the 4th barrier wall 581,
5th barrier wall 582, the height of the 6th barrier wall 583 are reduced (with reference to Fig. 5 a) successively.
Further, in order that the expansion process of frame glue 560 is more steady, the structure of frame glue 560 of formation is more reliable, this implementation
Example is further adjusted to the structure of the second limiting section 58.
As fig 5d, the 4th barrier wall 581 can be split as some groups of the 4th successive stopper 581A of head and the tail,
Gap w be present between the 4th stopper 581A." it is on the one hand the 4th barrier wall from integralization zero " by the 4th barrier wall 581
581 expand with heat and contract with cold flows down enough spaces, and saves cost；On the other hand also there are more fine settings for the expansion of frame glue 560
Space.The especially corner of frame glue 560, the expansion that the gap between the 4th stopper 581A gives frame glue 560 have enough
Fine setting space, be advantageous to the formation of frame glue 560.In consideration of it, the gap between the 4th stopper 581A can also may be used with identical
With difference, but it is not more than the 3rd spacing.
Similarly, it is also an option that making the 5th barrier wall 582 divide for the 5th successive stopper of some groups of head and the tail
Gap w be present between 582A, the 5th stopper 582A, and/or, another 6th barrier wall 583 is split as some groups
Gap w be present between the 6th successive from beginning to end stopper 583A, the 6th stopper 583A.So that frame glue 560 is in the second resistance
Stopper adjusts spaces coated with more.Gap w between 5th stopper 582A (the 6th stopper 583A) can with identical,
Can also be different, but it is not more than the 3rd spacing.
Certainly, the position between the 4th stopper 581A, the 5th stopper 582A, the 6th stopper 583A is unrestricted, can
, can also mutual dislocation neatly to correspond to.
Only selection the 5th barrier wall 582, the 6th barrier wall 583 " from integralization zero ", can also be kept into the 4th barrier wall 581
Complete enclosed construction, isolating for frame glue 560 and liquid crystal was so both may insure, the regulation needs of frame glue 560 can also be met
(with reference to figure 3f).
Gap between first substrate 51, second substrate 52 is supported in order to stable, one can be also mixed in the sealing space
A little septs 270, there is provided the support force of upper and lower two-layer substrate.Wherein, sept 570 can be spherical shape or column, at least one
The individual sept 570 is arranged between the liquid crystal layer 550 and the frame glue 560.
When first substrate 51, second substrate 52 in box processing procedure, it is necessary to well press, it is therefore desirable to control the first limiting section
54th, the size and position relationship between the second limiting section 58.For example, the first limiting section 54, second limiting section 58 can make it that
Maximum height sum is not more than the thickness of sept 570.In another example the first limiting section 54, the phase of the second limiting section 58 can make it that
Mutually dislocation " occlusion ", is mutually avoided, and space on the one hand can be more adjusted to frame glue, on the other hand also can effectively avoid influenceing liquid
The pressing of LCD panel.
