With reference to Fig. 1, in further the present embodiment, this chock insulator matter stopper slot C includes strip groove
C1 and/or point-like groove C2.The length of strip groove C1 groove port is more than the width of groove port,
Example, groove port can be rectangle.The shape of point-like groove C2 can be arbitrary, such as its
The shape of groove port can be regular polygon, can be circular, and now the entirety of point-like groove C2 is seen
Can be the hemisphere of depression, it is also possible to be irregular shape.
Use which kind of shape chock insulator matter stopper slot C can as required depending on.Example, if first
Chock insulator matter stopper slot C on substrate 31 needs the top limiting chock insulator matter (the most perpendicular in multiple directions
Straight and horizontal both direction) on movement, the most now can select point-like groove C2.Example,
If needing the movement on a direction (such as horizontal direction) with the chock insulator matter stopper slot C on substrate 1,
The most now can select strip groove C1.Certainly, first substrate 31 can also both arrange strip
Connected in star C1, also sets up point-like groove C2.
In order to design effect preferably chock insulator matter stopper slot C, based on ADS pattern under first analyzing
Liquid crystal indicator in, there is the reason of dark-state light leak, specially glass (i.e. substrate) produces
Retardation to combine the structure of ADS pattern itself be the main cause causing light leak.Below with this liquid
Crystal device includes color membrane substrates and array base palte, and PS be arranged on color membrane substrates as a example by carry out
Explanation.
Wherein, the main subjected to stress in source of glass substrate retardation, and the source of stress is PS
And the frictional force between its relative substrate (the most specifically array base palte).In color membrane substrates and battle array
After box is completed by row substrate, also there is certain decrement in main PS and array base palte upper surface,
Therebetween there is frictional force.According to formula Rm=Ct | σx-σy|, wherein, Rm represents retardation, C
Representing photoelastic coefficient, t represents glass substrate thickness, | σx-σy| represent because of main PS top and array base
Frictional force between plate and the stress that produces, wherein, σxAnd σyIt is respectively in x/y plane (glass lined
Place, end plane) interior glass substrate produce maximum principal stress and minimum principal stress.
Wherein, glass substrate subjected to stress formula is
Wherein, μ is coefficient of friction, and N is the contact area density (unit plane of PS and array base palte
Contact area in long-pending), Δ L is that (actually relevant to amount of liquid crystal, amount of liquid crystal is got over for the deformation quantity of PS
Little, PS compression is the most serious, and deformation quantity is the biggest), L is that the original height of PS is not (when i.e. having stress
The height of PS, namely the height of PS before color membrane substrates and array base palte are to box), K is PS
Young's modulus.
As can be seen here, if frictional force is the least, then the retardation that glass produces is the least, thus light leak amount is more
Little (wherein light leak index shows that the most greatly light leak degree is the biggest).And the size of frictional force depends on PS
The product of deformation quantity and contact area density.This structure also goes through verification experimental verification equally, such as following table
Shown in 1.
Table 1
In prior art, it is contemplated that the impact on frictional force of the contact area density, reduced by employing
The distribution of PS reaches this purpose；But, use this method frictional force to diminish, and make
Easily sliding, if sliding into pixel region in the top obtaining PS, it is likely that scratches alignment films, and then
Cause the appearance of locus coeruleus phenomenon.Another further aspect, in order to prevent the slip on PS top in prior art,
PS usually can be designed to the structure that frictional force is bigger, so it is generally required to bigger contact area,
The most still cannot well reduce light leak degree.In order to solve this problem, embodiment of the present invention column
The top of chock insulator matter 40 is supported in chock insulator matter stopper slot C on the first substrate, and at LCD
Plate 1 not by the case of external force, the bottom of the top of cylindrical spacer 40 and chock insulator matter stopper slot C
Between there is gap, so can not only reduce contact area, but also prevent the top of cylindrical spacer 40
Slide.
In order to allow cylindrical spacer 40 top and the bottom of chock insulator matter stopper slot C between have
Gap, chock insulator matter stopper slot C can be to be gradually reduced from opening cross section on earth, in order to when first
When substrate 31 and second substrate are to box, cylindrical spacer 40 can be stuck in chock insulator matter stopper slot C's
Stage casing, thus bottom with chock insulator matter stopper slot C does not contacts.
Preferably with reference to Fig. 5 a, the cross section of chock insulator matter stopper slot C is arc.For strip groove
For C1, those skilled in the art should understand that cross section here be cross section (in Fig. 1 AA ' to
Cross section), the now semi-cylindrical being generally shaped like depression of strip groove C1 or semiellipse post
Shape；It should be noted that, " partly " here can not be half, it is also possible to is only cylindrical or ellipse
Cylindrical sub-fraction.So, the top of chock insulator matter can be along the length side of strip groove C1
To slip, but owing to strip groove is in pixel delimited area 12, thus the cunning on this direction
Move and do not interfere with display；It addition, the top of chock insulator matter can also be along the width side of strip groove C1
To carrying out a certain degree of skew, but due to the stop of strip groove C1 sidewall so that chock insulator matter
Top be difficult to skid off groove in pixel region, and also beneficially chock insulator matter top return slide into initial
Position.For point-like groove C2, cross section here it can be appreciated that above-mentioned cross section,
Now point-like groove C2 can be substantially the strip groove that length is less.Certainly, point-like groove C2
Can also is that the cross section of its any direction is arc, now point-like groove C2 be generally shaped like recessed
The hemisphere fallen into or semielliptical, " partly " here can not be half, it is also possible to only spheroid,
Or ellipsoid sub-fraction.
Preferably, with reference to Fig. 5 b, the cross section of chock insulator matter stopper slot C can be that therefrom the heart depends on to both sides
The stairstepping of secondary rising.Understanding for cross section is referred to the explanation for Fig. 5 a.
Preferably, with reference to Fig. 5 c, the cross section of chock insulator matter stopper slot C can be inverted triangle.For cutting
The understanding in face is referred to the explanation for Fig. 5 a.
Preferably, with reference to Fig. 5 d, the cross section of chock insulator matter stopper slot C can be inverted trapezoidal.For cutting
The understanding in face is referred to the explanation for Fig. 5 a.
Scheme according to Fig. 5 a, Fig. 5 b, Fig. 5 c or Fig. 5 d arranges chock insulator matter stopper slot C, can
So that chock insulator matter stopper slot C is from groove port to bottom portion of groove, its aperture area is gradually reduced.So,
With reference to Fig. 7 a, Fig. 7 b, Fig. 7 c or Fig. 7 d, when the apex area of cylindrical spacer 40 is more than groove
Bottom area time, when liquid crystal indicator does not stresses, the top of chock insulator matter can be with bottom portion of groove
There is gap, thus, if not changing (the dottle pin in unit are of chock insulator matter distribution density in prior art
The number of thing), the most still can reduce the contact area density of chock insulator matter and first substrate 31, thus
Reduce frictional force, and then reduce dark-state light leak.Wherein, the top of above-mentioned cylindrical spacer 40 is against
Chock insulator matter stopper slot C may is that, the top of above-mentioned cylindrical spacer 40 is directly and first substrate 31
On chock insulator matter stopper slot C contact；Can also be that the top of cylindrical spacer 40 has thin film,
This thin film contacts, such as with the chock insulator matter stopper slot C on first substrate 31: this thin film can be to take
To film.
If it should be noted that the chock insulator matter stopper slot C on first substrate 31 is because being provided with dottle pin
Thing pad 20 is just formed, then chock insulator matter stopper slot C and the groove on chock insulator matter pad 20
Shape should be roughly the same.It addition, the formation material for chock insulator matter pad 20 does not does in the present embodiment
Limiting, such as it can be inorganic material, such as metal, quasiconductor etc.；Can also is that organic material,
Material that such as can be identical with flatness layer selection, it is also possible to be resin, it is particularly possible to use photonasty
Resin (material of photoresist).
It addition, the shape of cylindrical spacer 40 can be identical compared with technology, for cylinder；Generally
Because of the restriction of processing technology, practical situation is generally truncated cone-shaped, now the top of cylindrical spacer 40
For plane.Certainly, as shown in Figure 8, the top of cylindrical spacer 40 can also be the cambered surface protruded,
So so that cylindrical spacer 40 is after slip, it is easier to return to its initial position with initial
Shape.Now, can fit with the bottom of chock insulator matter stopper slot C in the top of cylindrical spacer 40,
Can also and the bottom of chock insulator matter stopper slot C between leave gap.
Preferably this display panels can be ADS (Advanced-Super Dimensional
Switching, senior super dimension field switch) type display panels, certain display panels can also
Be TN (wisted Nematic, twisted nematic) type, (In-Plane Switching puts down IPS
Face change) type, FFS (Fringe Field Switching, fringe field switching technology) type, blue phase
