Description

Liquid crystal display cells and manufacture method thereof
Technical field
The present invention relates to liquid crystal display cells, saying so in more detail makes liquid crystal display cells and the manufacture method thereof of dispersed liquid crystal in macromolecular compound.
Background technology
High-molecular dispersed liquid crystal display element, with the display mode of the light scattering effect that adopts the complex that constitutes by liquid crystal and macromolecular compound, be that the liquid crystal display cells of twisted nematic existing modes such as (TN) is different, do not need to be used to obtain the polarizer of rectilinearly polarized light.Therefore, because the utilization ratio height of light, so as the liquid crystal display cells of a new generation and noticeable, and carrying out active development research.
Above-mentioned high-molecular dispersed liquid crystal display element can be classified as follows.The 1st kind is called as NCAP (to row calibration curve phase), with polyvinyl alcohol (PVA) etc. nematic liquid crystal is made miniature little box body.The 2nd kind is called as PDLC (polymer-dispersed liquid crystal), the liquid crystal drop of globulate or ellipse of revolution shape roughly is dispersed in (for example, Society for informationdisplay international symposiumdigest ' 90 p.227-230) in the polymer matrix independently of each other.In addition, the 3rd kind be not make liquid crystal drop separate but make its part exist to be in contact with one another with the state that is connected (for example, the 22nd liquid crystal discussion solicit contributions in advance the collection p.403-404,1996).Further, the 4th kind is called as PNLC (polymkeric substance nematic liquid crystal), has to make macromolecule resin with the three-dimensional netted structure that spreads in the external phase of liquid crystal (for example, p.190 No. 5304323, the 15th time liquid crystal discussion of United States Patent (USP) solicit contributions collection in advance, 1989).
In existing high molecule liquid crystal decentralized display element, usually only adopt any structure in above-mentioned.
Here, for example, make a part of liquid crystal drop, make by the following method to be in contact with one another the high molecule liquid crystal decentralized display element (with reference to figure (31a)) that exists with the state that is connected.
At first, the last substrate 1001 and the following substrate 1002 that are oppositely arranged is bonding by encapsulant 1006, make it form uniform gap.Then, between last substrate 1001 and following substrate 1002, inject the potpourri that comprises liquid crystal material and polymerizable monomer, polymerization temperature and exposure intensity are set at rated condition, and shine this potpourri with ultraviolet ray.Thus, make monomer polymerization, thereby phase is separated.And carrying out above-mentioned when irradiation ultraviolet ray, above-mentioned exposure intensity is evenly distributed in the plate face.
Consequently, according to above-mentioned condition, between two substrates, formation make liquid crystal material be dispersed in state in the polymer matrix or liquid crystal material with the form of continuous connection be dispersed in the polymer matrix state (for example, reference: flat-panel monitor ' 91, Nikkei BP society, p.221).
But the liquid crystal drop that makes of practicability is the mutual fully high molecule liquid crystal decentralized display element of independent structures in TFT type liquid crystal board in fact, exists and makes the high problem of poor contrast or driving voltage because of scattering is low.
The low reason of aforesaid scattering is as follows.That is, under the situation of separate liquid crystal drop, its particle diameter is about 0.8 μ m, if press liquid crystal number percent, this is about as much as 69%.Greater than above-mentioned value, then a part of liquid crystal drop will become the connection form as particle diameter and liquid crystal number percent.Here, for example when the light wavelength of incident was the 0.4 μ m left and right sides, in order to obtain enough scatterings, the particle diameter of liquid crystal drop was necessary for about 1.2 μ m.This is equivalent to about 75% by liquid crystal number percent.But, as mentioned above, because the particle diameter of separate liquid crystal drop is too small, so scattering is low.Therefore, make contrast deterioration.In addition, the reason that uprises of driving voltage is as follows.That is, as mentioned above, because scattering is low under the situation of separate liquid crystal drop, so, in order to obtain to be in contact with one another the scattering same, just must strengthen the gap of liquid crystal board with situation about being connected with a part of liquid crystal drop.Consequently, driving voltage is uprised.
In addition, at a part of liquid crystal drop is in the high molecule liquid crystal decentralized display element or polymer network type high molecule liquid crystal decentralized display element of interconnective structure, exists because of environment temperature changes the macromolecule resin that makes near the viewing area the encapsulant and produces the uneven problem of demonstration that chaps thereby striated takes place.
Discoveries such as present inventor, for example carrying out placing under the situations such as inspection operation of cool to room temperature behind the certain hour under the hot environment for the reliability of the temperature characterisitic of estimating above-mentioned high-molecular dispersed liquid crystal display element, the demonstration that aforesaid striated has taken place is inhomogeneous.Below, the uneven genesis mechanism of this demonstration is described.That is, as high-molecular dispersed liquid crystal display element was for example being placed 24 hours under 80 ℃ the high temperature, then as Figure 31 (b) shown in, macromolecule resin 1005 and liquid crystal 1004 expansions.At this moment, the encapsulant 1005 of support substrate also expands along with temperature, but the degrees of expansion of encapsulant 1005 is quite little.Therefore, the distortion of convex takes place in the section of liquid crystal board on substrate up and down.Because the viscosity of liquid crystal at high temperature sharply reduces, institute so that liquid crystal be easy to flow.And the edge part of going up substrate 1001 and following substrate 1002 is being fixed by encapsulant 1005.Thus, complex layer 1003, be subjected on the direction of arrow shown in this figure from the pressure of substrate 1001 and following substrate 1002.Therefore, make near the encapsulant 1006 liquid crystal be subjected to this pressure and in the internal flow of liquid crystal board.Then, when making the liquid crystal board cool to room temperature, the viscosity of liquid crystal at room temperature uprises.Thus, the liquid crystal that flows to the liquid crystal board central portion can not be returned near the encapsulant 1006, the result reduces near the liquid crystal density the encapsulant 1006.Therefore, in the time of near the macromolecule resin matrix when pressure is added in encapsulant 1006 from last substrate 1001 and following substrate 1002, will produce 1007 (with reference to Figure 31 (c)) that chap.Therefore, it is inhomogeneous to produce the demonstration of striated at the edge part of display panel.
As mentioned above, be the high-molecular dispersed liquid crystal display element of mutually complete independent structures for liquid crystal drop, though it is inhomogeneous to can't see the demonstration of striated on display panel, its contrast is originally just low.On the other hand, for a part of liquid crystal drop is the high-molecular dispersed liquid crystal display element or the polymer network type high-molecular dispersed liquid crystal display element of interconnective structure, though contrast is good, can see that on display panel the demonstration of striated is inhomogeneous.That is, can realize that good contrast can prevent to show the high-molecular dispersed liquid crystal display element of uneven generation again, does not see up to now as yet.
On the other hand, the demonstration of the above-mentioned striated that causes because of taking place to chap is inhomogeneous, and also mechanism as described below takes place.And the demonstration of the striated of mentioning here is inhomogeneous, even be that liquid crystal drop is dispersed in independently of each other under the situation of the high-molecular dispersed liquid crystal display element in the macromolecule resin matrix and also can takes place in the structure that is known as PDLC.Hereinafter, be that example describes with this PDLC.
Above-mentioned high-molecular dispersed liquid crystal display element shown in figure 32, structurally is that complex layer 2103 is clamped between the last substrate 2101 and following substrate 2102 that is formed with show electrode 2014,2014.Between substrate 2101 and the show electrode 2104, forming colour filter 2106 on above-mentioned.Above-mentioned complex layer 2103 is close to substrate 2101 and following substrate 2102 forms.In addition, complex layer 2103 has and makes liquid crystal drop be dispersed in structure in the matrix phase that is made of macromolecular compound.
In above-mentioned high-molecular dispersed liquid crystal display element, complex layer 2103 expands along with the variation of environment temperature or shrinks, and make near the macromolecule resin the encapsulant 2105 produce be full of cracks, thereby exist the inhomogeneous such problem of demonstration that striated takes place.
Aforesaid demonstration is inhomogeneous, for example takes place during the inspection operations such as thermal shock of cool to room temperature carry out placing certain hour under hot environment for the reliability of the temperature characterisitic of estimating above-mentioned high-molecular dispersed liquid crystal display element after.That is, as high-molecular dispersed liquid crystal display element is at high temperature placed certain hour, then shown in Figure 33 (b), complex layer 2103 expands.At this moment, under above-mentioned environment, the viscosity of complex layer 2103 reduces rapidly, so the flowability of this complex layer 2103 increases.And the edge part of going up substrate 2101 and following substrate 2102 is being fixed by encapsulant 2105.Thus, complex layer 2103, be subjected on the direction of arrow shown in this figure from the pressure of substrate 2101 and following substrate 2102.Consequently, macromolecule resin is flowed to the liquid crystal board central portion, institute is so that this central portion further expands (with reference to Figure 33 (c)).Then, when making the liquid crystal board cool to room temperature, because of the viscosity degree increase of complex layer 2103 reduces flowability, so that near the liquid crystal density the encapsulant 2105 reduce, therefore encapsulant 2105 near, produce 2110 (with reference to Figure 33 (d)) that chap.Consequently, it is inhomogeneous to produce the demonstration of striated at the edge part of display panel.
In addition, as if above-mentioned existing high-molecular dispersed liquid crystal display element is such, complex layer 2103 is close to substrate 2101 and following substrate 2102, then when for example making display panel be subjected to pushing by pen touch input etc., exists display panel the uneven problem of demonstration takes place.
Below, describe this problem in detail.Figure 34 is the vertical view when last substrate 2101 sides are observed existing high-molecular dispersed liquid crystal display element.As pushing the A point shown in this figure from following substrate side 2102 sides, then to be close under the state of substrate 2101 and following substrate 2102 at complex layer 2103, complex layer 2103 is also along with last substrate 2101 and substrate 2102 deflection together (with reference to Figure 35) down.Therefore, at the deflection division 2121,2121 of liquid crystal board amount of deflection maximum, between last substrate 2101 and the complex layer 2103, and down between substrate 2102 and the complex layer 2103, with direction of arrow generation shear stress 2122 shown in the figure respectively.Under the effect of this shear stress 2122, by the short space that macromolecule resin crosses, spherical state from the outset is deformed into perpendicular to the length of the direction of last substrate 2101 short space (with reference to Figure 36) less than the flat of the length of the direction that is parallel to substrate 2101.Liquid crystal molecule in the short space that is enclosed in flat is arranged by the shear stress direction.Therefore, when electric field OFF, on zone 2111, transmitted light is scattered and the outward appearance that is creamy white.But in the zone 2110 that is wing, the refractive index corresponding with incident direction reduces and scattering weakened, thereby presents slightly sub-translucent outward appearance, and on display panel demonstration inhomogeneous (with reference to Figure 34) takes place.On the other hand, when electric field ON, the zone 2110 interior threshold voltages that are wing compare the little of zone 2111, so produce deviation on threshold voltage.Therefore, even in this case, also can show inhomogeneous.
In addition, above-mentioned existing high molecule liquid crystal decentralized display element also exists the low problem of light utilization ratio that colour mixture takes place, reach black matrix between the color material film RGB of colour filter 2106.
That is, as shown in figure 37, for example, when inciding complex layer 2103, be scattered from the incident light of following substrate 2102 side incidents.At this moment, the part of the incident light after the scattering is absorbed by black matrix and causes light loss.On the other hand, remaining light is at the color material film G that arrives colour filter 2106 by complex layer 2103 back.Further, when when this color material film G makes progress substrate 2101 incidents, light is scattered into radial.Here, when last substrate 2101 is made of glass etc., its refractive index n g(for example, n g=1.5) greater than aerial refractive index n Air(=1.0).Therefore, make part total reflection on the border of last substrate 2101 and air of scattered light sometimes.Colour mixture then will take place as inciding in the adjacent color material film B in this light after by total reflection.
In addition, in above-mentioned existing high-molecular dispersed liquid crystal display element, also has following problem.That is, complex layer 2103 is applied electric field and carry out on display panel, whether existing the inspection of the show state of point defect or line defect.This checks operation, the dummy cell that assembles is being injected liquid crystal material and carrying out after constituting liquid crystal cells (this situation is even the existing liquid crystal display cells of TN type too).Therefore, confirming that defective by complex layer 2103 grade causes under the situation of the defective of display panel etc., the opposed substrate that has the colour filter etc. of high price also must be discarded, so exist the problem that causes cost high.
As above situation has been concluded, then to listing problem as described below at above-mentioned existing high-molecular dispersed liquid crystal display element.
At liquid crystal drop is in the high-molecular dispersed liquid crystal display element of mutually complete independent structures, so because of the low poor contrast of scattering, or the driving voltage height.
That demonstration takes place is inhomogeneous because of the deflection of liquid crystal board or for estimating thermal shock test that reliability carries out etc.
When being provided with colour filter and carrying out colour when showing, will the colour mixture between color material film RGB take place or cause the reduction of light utilization ratio because of the light loss of black matrix.
When by show checking when finding defective, the opposed substrate that has colour filter at high price etc. also will be discarded, so cause the cost raising.

In addition, one group of the present invention is based on identical or similar design.But, because each invention is with different embodiment realizations, so will divide into I invention group and II invention group with closely-related each invention of this group of the present invention in this manual.And, hereinafter, in order each grouping (invention group) is illustrated its content.
(1) I invention group is developed for reaching above-mentioned the 1st purpose, relates generally to inhomogeneous, while liquid crystal display device with excellent and the manufacture method thereof on display characteristics such as contrast and scattering of demonstration of the striated on the elimination display panel.Promptly, for reaching above-mentioned the 1st purpose, liquid crystal display cells, have respectively at medial surface between a pair of substrate of electrode, configuration makes liquid crystal drop be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding by encapsulant, this liquid crystal display cells is characterised in that: above-mentioned high molecule liquid crystal complex layer, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute, or dispersed liquid crystal is remained in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, when forming, the outer peripheral face of above-mentioned high molecule liquid crystal complex layer and the inner peripheral surface of encapsulant are adjacent to, and, being divided into the main part that makes above-mentioned high molecule liquid crystal complex layer is the viewing area, and the edge part of the close above-mentioned encapsulant of this high molecule liquid crystal complex layer is a non-display area, further, the high molecule liquid crystal complex layer of above-mentioned viewing area, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute with the interconnective state of a part, or dispersed liquid crystal is remained in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, the interval that makes the particle diameter of liquid crystal drop of above-mentioned viewing area or grid when forming is different with the interval of the particle diameter of the liquid crystal drop of above-mentioned non-display area or grid.
According to said structure, because the interval that makes the particle diameter of liquid crystal drop of non-display area or grid when forming is different with the interval of the particle diameter of the liquid crystal drop of viewing area or grid, so, can prevent near the high molecule liquid crystal complex layer the encapsulant, to produce be full of cracks when being placed on environment that environment temperature for example changes to low temperature from high temperature when carrying out fail-test down.
Specifically, when the interval of the particle diameter of the liquid crystal drop of non-display area or grid less than the interval of the particle diameter of the liquid crystal drop of viewing area or grid and near the zone encapsulant be liquid crystal drop disperse independently of each other structure the time, even environment temperature rises, liquid crystal also is difficult to move to central portion.Consequently, can prevent that near the liquid crystal density of the non-display area the encapsulant from reducing, so can prevent the generation of chapping.On the other hand, when the interval of the particle diameter of the liquid crystal drop of non-display area or grid during, liquid crystal is become flow easily greater than the interval of the particle diameter of the liquid crystal drop of viewing area or grid.That is, when the interval of the particle diameter of liquid crystal drop or grid is big, the liquid crystal during no matter to high temperature expand or during to cooling from around the rapid variation of the pressure that is subjected to of macromolecule resin, liquid crystal all has servo-actuated, and makes between the liquid crystal drop and also can move at an easy rate.Therefore, the liquid crystal density that can suppress near the non-display area the encapsulant reduces, so can prevent the generation of chapping.
And, in the viewing area, the structure of formed high molecule liquid crystal complex layer with make liquid crystal drop with separate and structure that state that disperse remains in the matrix that comprises macromolecular compound and constitute is different, so can under the contrast good state, prevent show inhomogeneous.
In addition, the test period of aforesaid fail-test has nothing in common with each other, so when this test period in short-term, the difference at the particle diameter of the particle diameter of the liquid crystal drop by making non-display area or the interval of grid and the liquid crystal drop of viewing area or the interval of grid is slightly different, can prevent the generation of chapping.
In addition, for reaching above-mentioned the 1st purpose, liquid crystal display cells, have respectively at medial surface between a pair of substrate of electrode, configuration makes liquid crystal drop be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding by encapsulant, this liquid crystal display cells is characterised in that: above-mentioned high molecule liquid crystal complex layer, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute, or dispersed liquid crystal is remained in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, when forming, the outer peripheral face of above-mentioned high molecule liquid crystal complex layer and the inner peripheral surface of encapsulant are adjacent to, and, being divided into the main part that makes above-mentioned high molecule liquid crystal complex layer is the viewing area, and the edge part of the close above-mentioned encapsulant of this high molecule liquid crystal complex layer is a non-display area, further, the high molecule liquid crystal complex layer of above-mentioned viewing area, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute with the interconnective state of a part, or dispersed liquid crystal is remained in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, when forming, make the liquid crystal number percent of above-mentioned viewing area different with the liquid crystal number percent of above-mentioned non-display area.
According to said structure, owing to when forming, make the liquid crystal number percent of non-display area different with the liquid crystal number percent of viewing area, so, can prevent near the high molecule liquid crystal complex layer the encapsulant, to produce be full of cracks when being placed on environment that environment temperature for example changes to low temperature from high temperature when carrying out fail-test down.
Specifically, when the liquid crystal number percent of non-display area less than the liquid crystal number percent of viewing area and near the zone encapsulant be liquid crystal drop disperse independently of each other structure the time, even environment temperature rises, liquid crystal also is difficult to move to central portion.Consequently, can prevent that near the liquid crystal density of the non-display area the encapsulant from reducing, so can prevent the generation of chapping.On the other hand, when the liquid crystal number percent of non-display area during greater than the liquid crystal number percent of viewing area, the particle diameter of the liquid crystal drop of non-display area or the interval of grid will be greater than the particle diameter of the liquid crystal drop of viewing area or the intervals of grid.Consequently, liquid crystal is become flows easily.That is, the liquid crystal during no matter to high temperature expand or during to cooling from around the rapid variation of the pressure that is subjected to of macromolecule resin, liquid crystal all has servo-actuated, and also can move at an easy rate between liquid crystal drop.Therefore, the liquid crystal density that can suppress near the non-display area the encapsulant reduces, so can prevent the generation of chapping.
And, in the viewing area, the structure of formed high molecule liquid crystal complex layer with make liquid crystal drop with separate and structure that state that disperse remains in the matrix that comprises macromolecular compound and constitute is different, so can under the contrast good state, prevent show inhomogeneous.In addition, the test period of aforesaid fail-test has nothing in common with each other, thus when this test period in short-term, the difference of the liquid crystal number percent by making non-display area and the liquid crystal number percent of viewing area is slightly different, can prevent the generation of chapping.
Here, the liquid crystal number percent of above-mentioned viewing area and the liquid crystal number percent of above-mentioned non-display area poor is preferably at least more than 5%.
In addition, for reaching above-mentioned the 1st purpose, liquid crystal display cells, have respectively at medial surface between a pair of substrate of electrode, configuration makes liquid crystal drop be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding by encapsulant, this liquid crystal display cells is characterised in that: above-mentioned high molecule liquid crystal complex layer, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute, or make liquid crystal drop disperse to remain in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, when forming, the outer peripheral face of above-mentioned high molecule liquid crystal complex layer and the inner peripheral surface of encapsulant are adjacent to, further, will the zone part in addition of be full of cracks take place as the viewing area near the above-mentioned encapsulant in the whole zone of above-mentioned high molecule liquid crystal complex layer.
As mentioned above, for example make environment temperature from high temperature under the situations such as fail-test that low temperature changes, owing to structurally make the viewing area not comprise near the zone of encapsulant that generation is chapped, so can prevent from display panel, to see that the demonstration of the striated that causes because of this be full of cracks is inhomogeneous.
In addition, for reaching above-mentioned the 1st purpose, liquid crystal display cells, have respectively at medial surface between a pair of substrate of electrode, configuration makes liquid crystal drop be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding by encapsulant, this liquid crystal display cells is characterised in that: above-mentioned high molecule liquid crystal complex layer, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute, or dispersed liquid crystal is remained in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, and, when forming, the outer peripheral face of above-mentioned high molecule liquid crystal complex layer and the inner peripheral surface of encapsulant are adjacent to, further, near the inside of the be full of cracks that the above-mentioned encapsulant of above-mentioned high molecule liquid crystal complex layer, takes place, the material that filling mainly is made of liquid crystal.
According to said structure, by the material that the inside filling in be full of cracks mainly is made of liquid crystal, the refringence with on every side high molecule liquid crystal complex layer of can reducing to chap, thereby can make be full of cracks itself no longer noticeable.
In addition, for reaching above-mentioned the 1st purpose, liquid crystal display cells, have respectively at medial surface between a pair of substrate of electrode, configuration makes liquid crystal drop be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding by encapsulant, the feature of this liquid crystal display cells also is: above-mentioned high molecule liquid crystal complex layer, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute, or dispersed liquid crystal is remained in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, and the outer peripheral face of above-mentioned high molecule liquid crystal complex layer and the inner peripheral surface of encapsulant are fitted, further make the material that mainly constitutes be filled near the inside of the be full of cracks that above-mentioned encapsulant, produces of above-mentioned high molecule liquid crystal complex layer by liquid crystal.
By the inside with the material filling be full of cracks that mainly is made of liquid crystal, the be full of cracks part and the refringence of on every side high molecule liquid crystal complex layer are diminished as above-mentioned knot, its result makes be full of cracks itself become not obvious.
And then, for reaching above-mentioned first purpose, liquid crystal display cells, have its liquid crystal drop of configuration between a pair of substrate of electrode in the inboard respectively and be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding with encapsulant, this liquid crystal display cells is characterised in that, its liquid crystal drop of above-mentioned high molecule liquid crystal complex layer disperses to remain on and comprises in basic unit's external phase that macromolecular compound constitutes or its liquid crystal drop disperses to remain in the net of three the pseudostructure that comprises that macromolecular compound constitutes, further, inward flange at above-mentioned encapsulant, the width frame shape zone more than 1.5mm at least is set, and the viewing area is located at the inboard in above-mentioned frame shape zone.
According to said structure, making inner circumference width that be full of cracks occurs in self-sealing material at least in the frame shape zone more than 1.5mm, and irrelevant with the area size of liquid crystal board.Therefore, by the viewing area being located at least the inboard in above-mentioned frame shape zone, can prevent from reliably in the viewing area, to chap.Consequently, it is inhomogeneous the demonstration of the striated that caused by this be full of cracks can not occur on display panel.
In addition, for reaching above-mentioned the 1st purpose, liquid crystal display cells, have respectively at medial surface between a pair of substrate of electrode, configuration makes liquid crystal drop be dispersed in high molecule liquid crystal complex layer in the macromolecular compound, and it is above-mentioned a pair of substrate is bonding by encapsulant, this liquid crystal display cells is characterised in that: the viewing area is set and at the outer peripheral frame shape non-display area of this viewing area on above-mentioned high molecule liquid crystal complex layer, the high molecule liquid crystal complex layer of above-mentioned viewing area, make liquid crystal drop disperse to remain in the matrix external phase that comprises macromolecular compound and constitute with the interconnective state of a part, or make liquid crystal drop disperse to remain in the net of the three-dimensional netted matrix that comprises macromolecular compound and constitute, the high molecule liquid crystal complex layer of above-mentioned non-display area, with the liquid crystal drop of roughly globulate or ellipse of revolution shape with separate and state that disperse remains in the matrix that comprises macromolecular compound and constitute.

The structure of above-mentioned TFT substrate 102 is, forms TFT (not shown) as on-off element, and and the pixel capacitors 105 that is electrically connected of this TFT and source electrode line 108 etc. on substrate 111 down.In more detail, above-mentioned TFT and pixel capacitors 105, source electrode line 108 etc., formation in the zone suitable on following substrate 111 with viewing area 201.In addition, on following substrate 111, dielectric film 109 is being set also, is making it cover above-mentioned TFT and pixel capacitors 105.On the other hand, the structure of above-mentioned opposed substrate 103 is to form opposite electrode 107 etc. on last substrate 112.In addition, on above-mentioned opposite electrode 107, dielectric film 109 is being set also.In addition, be used for the encapsulant 106 that TFT substrate 102 and opposed substrate 103 is bonding, press the formation of frame shape at the edge part of liquid crystal board.
Here, between viewing area 201 that forms above-mentioned TFT and pixel capacitors 105 etc. and encapsulant 106, the width frame shape non-display area 202 more than 1.5mm at least is set.
In more detail, when for example making liquid crystal board, will the polymeric resin matrix materialization compound and the liquid crystal drop of liquid crystal board inside be expanded, and liquid crystal board itself is also expanded 80 ℃ of long-time down placements.Near the encapsulant 106 liquid crystal owing to the distortion of descending substrate 111 and last substrate 112 is under pressure, thereby flows in liquid crystal board.After this, when cool to room temperature,, and near the fragility of the macromolecule resin matrix the sealing material 106 is increased because liquid crystal the flowing of liquid crystal board inside, makes near the liquid crystal density the encapsulant 106 reduce.Further, by under substrate 112 and 111 pairs of above-mentioned macromolecule resin matrix applied pressures of following substrate, on macromolecule resin matrix, produce and chap 110.The zone that this be full of cracks takes place is equivalent to above-mentioned non-display area 202.Here, why make non-display area 202 be at least the frame shape zone of width more than 1.5mm, be based on the result of Fig. 3.Fig. 3 illustrates the variation of the distance of encapsulant corresponding with the standing time under 80 ℃ 106 and be full of cracks 110.Can know from this Fig. 3 and to find out, even be 60 hours the standing time under 80 ℃, encapsulant 106 and be full of cracks 110 apart from d (mm), maximum is also just about 1.45mm.Consequently, non-display area 202 only need be at least the frame shape zone of width more than 1.5mm and get final product.Therefore, in the liquid crystal display cells of present embodiment, because the frame shape zone (non-display area 202) of 1.5mm is being set, thereby the generation area of be full of cracks 110 is not comprised in the viewing area 201, therefore, even make fail-test that environment temperature changes to low temperature from high temperature etc., can not see also that on display panel the demonstration of striated is inhomogeneous.As shown in Figure 4, above-mentioned encapsulant 106 and be full of cracks 110 apart from d (mm), be illustrated in the distance between the inner peripheral surface of the be full of cracks 110 of innermost side near the be full of cracks 110 that take place the encapsulant 106 and sealing material 106.
In addition, the liquid crystal board gap between TFT substrate 102 and the opposed substrate 103 is 10 μ m, but in the present embodiment, is not limited thereto, as long as in the scope more than 3 μ m, below the 15 μ m.As in above-mentioned numerical range, 110 the generation area of then chapping is the frame shape zone of 1.5mm for the inner peripheral surface width from encapsulant 106.Here, in the liquid crystal board more than 3 inches for example, there is not dependence in the generation area of be full of cracks 110 to its size.Specifically, when making liquid crystal board at high temperature place the back cool to room temperature for a long time, by under substrate 112 and 111 pairs of above-mentioned macromolecule resin matrix applied pressures of following substrate, generation chaps 110 near the macromolecule resin matrix encapsulant 106.The degree that this pressure applies is subjected to the influence of area of liquid crystal board little, and mainly is that the influence in liquid crystal board gap is big.Therefore, in above-mentioned numerical range 3 μ m～15 μ m, it is the zone of 1.5mm that be full of cracks 110 occurs in from the inner peripheral surface width of encapsulant 106, and irrelevant with the size of liquid crystal board.
In addition, when the liquid crystal board gap surpassed 15 μ m, the driving voltage that is used to drive high molecule liquid crystal complex layer 104 increased considerably, and when less than 3 μ m, the transmittance of liquid crystal board increases also makes the scattering power reduction, thereby was unsuitable.Therefore,, the increasing considerably of driving voltage of high molecule liquid crystal complex layer 104 can be suppressed to be used to drive, the reduction of contrast can be suppressed simultaneously by above-mentioned liquid crystal board gap is set in the above-mentioned numerical range.
Above-mentioned TFT substrate 102 and opposed substrate 103 as long as any one has transmitance at least, are not done special the qualification.Therefore, a kind of substrate can be opaque substrates such as silicon substrate, in this case, has the structure of reflecting plate by employing, can constitute the liquid crystal display cells of reflection-type.As substrate, for example can adopt transparent substrates or the plastic that constitutes by glass, quartz etc. with above-mentioned transmitance.In this case, the material of TFT substrate 102 and opposed substrate 103 also can be different.
In addition, above-mentioned pixel capacitors 105 and opposite electrode 107 for example are the nesa coatings that is made of indium tin oxide (ITO:Indium TinOxide).
Above-mentioned high molecule liquid crystal complex layer 104 is structures that the part that makes liquid crystal drop forms with the state that is in contact with one another and is connected.But the existence of above-mentioned liquid crystal drop is not limited thereto, and for example, also can be to make macromolecular compound form three-dimensional netted and so that liquid crystal remains on the structure that the state in this net disperses.Here, the particle diameter of liquid crystal drop or the interval of grid are with scattering, be that gain G has correlationship.Above-mentioned gain G is represented with following formula.
G=(liquid crystal board brightness (nt)/liquid crystal board illumination (lx)) * π
When the concerning of the particle diameter of considering above-mentioned liquid crystal drop and gain G, there is optimum value in the particle diameter of this liquid crystal drop near about 1.2 μ m.In more detail, as greater than 1.2 μ m, then blue scattering of light reduction, otherwise, as less than 1.2 μ m, then red scattering of light reduction.That is, the both is that gain becomes the reduction that causes contrast greatly.Therefore, the particle diameter of the liquid crystal drop of viewing area 201 preferably is set at best particle diameter promptly near 1.2 μ m.And the interval of above-mentioned grid is by with observations such as microscopes and ask for the value that the mean value apart from a～c for example shown in Figure 5 calculates.
As above-mentioned liquid crystal, can adopt various liquid crystal such as near normal temperature, be mesomorphic state nematic liquid crystal, cholesteryl liquid crystal, smectic liquid crystal.These liquid crystal can use a kind, also can use mixing more than 2 kinds.In addition, as macromolecular compound,, do not do special the qualification as long as have transmitance and after forming high molecule liquid crystal complex layer 104, liquid crystal is remained in the macromolecule resin matrix.Specifically, for example use ultraviolet curing resin, thermohardening type (heat be separated type) resin etc. to get final product.As above-mentioned ultraviolet curing resin, for example can enumerate epoxy is resin, propylene resin etc.On the other hand, as above-mentioned thermohardening type resin, for example can enumerate epoxy and be resin, urethanes and be resin, polyamide-based resin, urea is resin, polyester based resin etc.
As above-mentioned encapsulant 106, do not do special the qualification, can enumerate thermohardening type encapsulant, ultraviolet hardening encapsulant, reach the compound encapsulant of thermohardening type and ultraviolet hardening etc.
As above-mentioned dielectric film 109,109, do not do special qualification, any can the use in polyimide type, the polyamide acid type.In addition, also can adopt the dielectric film that constitutes by mineral compound.When the dielectric film 109,109 that adopts as shown in this embodiment, has the effect that the voltage retention that can make high molecule liquid crystal complex layer 104 further improves.
As mentioned above, the liquid crystal display cells of present embodiment is characterised in that making the generation area of be full of cracks 110 is non-display area 202, and separates with the viewing area.In addition, above-mentioned non-display area 202 plays width by the inner peripheral surface of self-sealing material 106 and constitutes in the frame shape zone more than 1.5mm at least.Therefore, on display panel, the demonstration that striated can not take place is inhomogeneous, thereby the liquid crystal display cells that can obtain having good display characteristics.
Instantly the material of substrate 111 and last substrate 112 not simultaneously since when high temperature both degrees of expansion difference, so easier the be full of cracks.But, in the present embodiment, the generation area of be full of cracks is not included in the viewing area 201 owing to setting this viewing area 201, so, even under the different situation of aforesaid material, also be very effective.
In addition, in the present embodiment, the driven with active matrix that adopts TFT has been described, but the present invention being not limited thereto, also can be simple matrix driving.
Further, in above-mentioned be full of cracks 110 inside, also can clog the material that mainly constitutes by liquid crystal.As adopt this mode, then can reduce the refringence with the zone of be full of cracks beyond 110, thereby can make this be full of cracks 110 itself no longer noticeable.Consequently,, also can be included in the viewing area 201, thereby display panel is enlarged even chap 110 generation area.
As the method for filling above-mentioned be full of cracks 110 inside, do not do special the qualification, for example can enumerate the heat-treating methods of under 80 ℃, 2 hours condition, liquid crystal display cells 101 being annealed etc.In addition,, except that above-mentioned heat-treating methods, under the temperature more than 60 ℃, anneal, also have same effect as the method for filling be full of cracks 110.And the number of times of annealing also can carry out repeatedly.When repeatedly annealing since under the state of flow of liquid crystal increase certain time, flow to the liquid crystal of non-display area 202 so 201 central portion will take place from the viewing area, thereby be easy to filling and chap 110.
(embodiment 1-1)
The liquid crystal display cells of present embodiment 1 is corresponding to above-mentioned the 1st embodiment.Above-mentioned liquid crystal display cells is made by method shown below.That is, adopt vacuum evaporation and etching method, on the following substrate 111 that constitutes by glass, form pixel capacitors 105, source electrode line 108 and dielectric film 109 etc., constituted TFT substrate 102.On the other hand, on last substrate 112, form opposite electrode 107, dielectric film 109 etc., constituted opposed substrate 103 with method same as described above.
Then, on above-mentioned TFT substrate 102, coated heat curing type encapsulant (XN21-S ス ト ラ Network ト bonding agent, Mitsui East Asia chemistry (company limited) system) is as encapsulant 106, makes its coating be shaped as frame shape pattern in the leaving certain gaps uncovered by the economic plan of liquid crystal injecting port part.Further, by encapsulant 106 that above-mentioned TFT substrate 102 and opposed substrate 103 is bonding, making formed liquid crystal board gap is 10 μ m.
Then, between above-mentioned TFT substrate 102 and opposed substrate 103, import the potpourri of liquid crystal and ultraviolet hardening macromolecule dispersion material PNM201 (big Japanese ink chemistry (company limited) system) with vacuum impregnation.At this moment, the vacuum impregnating inlet 111 that forms on encapsulant 106 does not seal as yet.After this, be that 365nm and ultraviolet irradiation intensity are 80mW/cm with predominant wavelength 2The ultraviolet ray of (measuring with ultraviolet illuminometer UV-MO2 (-Network make made)) is shone, and makes the ultraviolet hardening macromolecule disperse the material polymerization.Thus, make and make liquid crystal drop be dispersed in polymeric web type liquid crystal cell in the macromolecule resin matrix with the form of continuous connection.Polymerization temperature when in addition, making irradiation ultraviolet radiation is 20 ℃.But, to polymerizing condition and ultraviolet irradiation intensity, be not limited to the above, need only suitably set as required and get final product.
Further, carried out sealing processing with joint filling material (trade name: TB3026, ス リ-bonding agent (company limited) system).Thus, produce the liquid crystal display cells of present embodiment 1.Viewing area 201, the inner peripheral surface that is located at self-sealing material 106 plays interior all sides that width is the frame shape non-display area 202 of 3mm.
Next step, to the liquid crystal display cells of present embodiment, the temperature around changing has also been carried out fail-test.Before this, when with the above-mentioned liquid crystal display cells of microscopic examination, confirmed near encapsulant 106, not chap.Fail-test is the annealing of liquid crystal display cells being carried out under 80 ℃ with baking oven 10 hours, then liquid crystal display cells is taken out from this baking oven and cool to room temperature.With this liquid crystal display cells of microscopic examination, and confirmed near the macromolecule resin the encapsulant 106, to take place be full of cracks 110.In more detail, in the gamut near the non-display area encapsulant 106 202 this be full of cracks 110 has taken place.In addition, to the zone of central portion up to maximum 1.5mm, be full of cracks 110 has taken place all from encapsulant 106.Like this, as make liquid crystal display cells be placed on environment temperature from high temperature under the environment that low temperature changes, then can be clear that the situation that be full of cracks takes place.And the liquid crystal display cells of present embodiment, because the frame shape non-display area 202 that width is 3mm is being set between encapsulant 106 and viewing area 201, so on the macromolecule resin matrix of viewing area 201, can not chap, thereby obtained good demonstration.
From the above as can be known, near make encapsulant 106 because of the environment temperature variation macromolecule resin matrix takes place in the liquid crystal display cells of be full of cracks, owing to make viewing area 201 be the zone beyond the be full of cracks generation area, so, can access and not show liquid crystal display cells inhomogeneous and that have high reliability and good display characteristics on the display panel.
Further, change the interval of encapsulant 106 and viewing area 201, and carried out same test.It the results are shown in following table 1.Be used to determine to show the metewand of uneven degree, be ◎ when in the viewing area 201 be full of cracks taking place, be zero when be full of cracks takes place the part of some pixels around the viewing area 201, when some pixels around the viewing area 201 all be full of cracks takes place almost the time be Δ, when from the viewing area 201 when thick and fast be full of cracks taking place with the border of non-display area 202 more than some pixels of inboard for *.

As can be seen from Table 1, when at interval less than 1.5mm,, confirmed that the demonstration of generation striated on display panel is inhomogeneous in the viewing area because the be full of cracks 110 of macromolecule resin matrix takes place.That is, the generation area of be full of cracks 110, the inner peripheral surface that can be described as at self-sealing material 106 rises in the frame shape zone that width is 1.5mm.Therefore, be at least 1.5mm as make its interval with encapsulant 106 when forming viewing area 201, it is inhomogeneous and obtain good demonstration then can to eliminate demonstration.Further, as the main implementation condition that reaches classic effect, can guarantee the interval that 3.0mm is above, be even more ideal.Here, when encapsulant 106 and viewing area 201 be spaced apart 3.0mm the time owing in viewing area 201, there is not be full of cracks,, non-display area 202 in, can sees and chap 110 so show well.This be full of cracks 110 is checked, found that be full of cracks 110 inside are vacuum.
Can confirm from above result, the liquid crystal display cells of present embodiment, even be full of cracks 110 takes place, the demonstration that striated also can not take place on display panel is inhomogeneous, thereby presents good display characteristic.
(embodiment 1-2)
The liquid crystal display cells of present embodiment 1-2 is corresponding to above-mentioned the 1st embodiment.
The liquid crystal display cells of present embodiment 1-2 is with the difference of the liquid crystal display cells of the foregoing description 1-1, and as the viewing area, and filling is the material of principal ingredient with the liquid crystal in be full of cracks 110 with the whole zone of high molecule liquid crystal complex layer 104.
At first, to make liquid crystal display cells with the same mode of the foregoing description 1-1.Then, 1-1 is the same with the foregoing description, and above-mentioned liquid crystal display cells has been implemented fail-test.After this fail-test, with microscopic examination above-mentioned liquid crystal display cells, and confirm near the macromolecule resin matrix the encapsulant 106, taking place to chap 110.Further, under 80 ℃, 2 hours condition, once more liquid crystal display cells 101 is annealed, make to be present in the material that mainly by liquid crystal constitute of be full of cracks around 110 and to flow into and clogged this be full of cracks 110 with baking oven.At this moment, reduce with the refringence in the zone of be full of cracks beyond 110, thereby make this be full of cracks 110 no longer noticeable.Therefore, under 110 the situation of having taken place to chap, confirmed to make this be full of cracks 110 no longer noticeable effectively by 110 fillings of will chapping such as heat-treating.
Can confirm from above result, the liquid crystal display cells of present embodiment, even be full of cracks 110 takes place, on display panel the demonstration of striated inhomogeneous also inconspicuous, thereby present good display characteristic.
[the 2nd embodiment]
According to Fig. 6～Fig. 7, the 2nd embodiment of the present invention is described as follows.Have the inscape of said function for liquid crystal display cells, be marked with prosign and it describe in detail is omitted with above-mentioned the 1st embodiment.
The liquid crystal display cells of present embodiment, compare with the structure of the liquid crystal display cells of above-mentioned the 1st embodiment, its difference is, the high molecule liquid crystal complex layer of non-display area had liquid crystal drop is dispersed in respectively independently the structure in the macromolecule resin matrix layer that is made of macromolecular compound.
Fig. 6 (a) is a sectional drawing of representing the liquid crystal display cells of present embodiment briefly.Shown in Fig. 6 (a),, the frame shape non-display area 202 that width is about 1.0mm is being set in the inboard of encapsulant 106.Further, in the inboard of this non-display area 202 viewing area 201 is being set.In above-mentioned non-display area 202, disperse keeping the liquid crystal drop 206 (with reference to Fig. 6 (c)) of roughly spherical in shape or ellipse of revolution shape with separate state.Different therewith, in viewing area 201, formation makes the part of liquid crystal drop 205 to be in contact with one another the structure (with reference to Fig. 6 (b)) that exists with the state that is connected.In addition, viewing area 201 also can be to make macromolecule resin matrix form three-dimensional netted and so that liquid crystal remains on the structure that the state in this net disperses.Shown in above-mentioned structure, because near the liquid crystal drop the encapsulant 106 is separate structure, so when temperature rose, this liquid crystal drop was difficult to move to inside.Consequently, can suppress the generation of the be full of cracks of non-display area 202.On the other hand, as described in above-mentioned first embodiment, the particle diameter of liquid crystal drop or the interval of grid, with scattering, be that gain G has correlationship, the particle diameter of liquid crystal drop preferably is approximately 1.2 μ m.
As the high molecule liquid crystal complex layer 200 of the main composition key element of present embodiment liquid crystal display cells, can form by the method for the following stated.
Fig. 7 is the sectional drawing that is used to illustrate above-mentioned liquid crystal display cells manufacture method.At first, it is bonding to be respectively equipped with the TFT substrate 102 or the opposed substrate 103 of pixel capacitors 105 and opposite electrode 107 in advance with encapsulant 106.Further, between above-mentioned TFT substrate 102 and opposed substrate 103, injecting with uncured resin monomers such as ultraviolet curing resin (macromolecule precursor) and liquid crystal material is the liquid crystal polymer potpourri of main material.Then, when to this liquid crystal polymer potpourri irradiation ultraviolet radiation, the uncured resin monomer polymerization also makes liquid crystal separate with macromolecule resin matrix phase.
Here, to above-mentioned ultraviolet ray, on viewing area 201 and non-display area 202, set different ultraviolet irradiation intensities.In more detail, make the exposure intensity of the exposure intensity of the 2nd ultraviolet ray 203 that is radiated at non-display area 202 greater than the 1st ultraviolet ray 204 that is radiated at viewing area 201.As mentioned above,, separate so can make above-mentioned liquid crystal and macromolecular compound carry out phase further owing to make the exposure intensity of the 2nd ultraviolet ray 203 big, so, in non-display area 202, can make liquid crystal drop 206 become independent respectively and structure that disperse.On the other hand, owing to make the exposure intensity of the exposure intensity of the 1st ultraviolet ray 204 less than the 2nd ultraviolet ray 203, so, can suppress the degree of carrying out that liquid crystal separates with the phase of macromolecular compound.Therefore, in viewing area 201, form the part make liquid crystal drop 205 and exist with the state that is connected or make macromolecule resin matrix form three-dimensional netted and so that liquid crystal remains on the structure that the state in this net exists to be in contact with one another.Thus, form high molecule liquid crystal complex layer 200.In addition, the width that makes non-display area 202 is that the reason of 1.0mm is, always can be subjected to from the influence of the light of back side retroeflection, thereby be difficult to making it less than 1.0mm when for example shining the 1st ultraviolet 204 grades.
Above-mentioned ultraviolet irradiation intensity as long as can obtain the structure of the liquid crystal drop 206 of the liquid crystal drop 205 of aforesaid viewing area 201 and non-display area 202, is not done special the qualification, can set arbitrarily.But ultraviolet irradiation intensity is big more, and then the degree of polymerization is high more, and the particle diameter of liquid crystal drop is diminished, so the exposure intensity that is radiated at non-display area 202 must be greater than the exposure intensity that is radiated at viewing area 201.
In addition, in order in the face of liquid crystal board, to change ultraviolet irradiation intensity, can enumerate the method for the ultraviolet cutoff filter of local configuration in liquid crystal board etc.For example, on viewing area 201, dispose cutoff filter, and on non-display area 202, dispose cutoff filter the wavelength filtering of 350nm with the wavelength filtering of 370nm.At this moment, the ultraviolet ray from same light emitted goes out under the effect of above-mentioned cutoff filter, can make the ultraviolet irradiation intensity that is radiated at non-display area 202 bigger than viewing area 201.According to the method described above.Can make the irradiation number of times is 1 time, thereby can simplify manufacturing process.
As mentioned above, the liquid crystal display cells of present embodiment is characterised in that, near the zone encapsulant 106 (non-display area 202), forms and makes the separate and structure of disperseing of liquid crystal drop.Therefore, even temperature on every side rises, liquid crystal drop 206 also is difficult to move to inside, thereby can prevent that the liquid crystal density in the non-display area 202 from reducing, so can prevent the generation of chapping, also can prevent the uneven generation of the demonstration that causes because of this be full of cracks thus.And, in viewing area 201, in the matrix external phase that makes liquid crystal drop 205 disperse to remain on to comprise macromolecular compound to constitute, so can under the contrast good state, prevent to show uneven generation.In addition, owing to make non-display area 202 for width is at least 1, the frame shape zone that 0mm is above is so can make the viewing area further enlarge.
(embodiment 2)
The liquid crystal display cells of present embodiment 2 is corresponding to above-mentioned the 2nd embodiment.Above-mentioned liquid crystal display cells is made by method shown below.
That is, the mode with same with the foregoing description 1 by vacuum evaporation and etching and processing, forms pixel capacitors 105, source electrode line 108, dielectric film 109 etc. on the following substrate 111 that is made of glass, constituted TFT substrate 102.Further, behind printing ability プ ト マ-AL5417 (Japan SYnthetic Rubber Co. Ltd's system) on the following substrate 111, be solidified to form dielectric film 109 with print process with baking oven for heating.On the other hand, on last substrate 112, similarly form opposite electrode 107 by vacuum evaporation and etching with above-mentioned.Further, behind coating オ プ ト マ-AL5417 on the last substrate 112,, constituted opposed substrate 103 with the above-mentioned dielectric film 109 that similarly forms with curing oven.
Then, on above-mentioned TFT substrate 102, coated heat curing type encapsulant (XN21-S ス ト ラ Network ト bonding agent, Mitsui East Asia chemistry (company limited) system) is as encapsulant 106, makes its coating be shaped as frame shape pattern in the leaving certain gaps uncovered by the economic plan of liquid crystal injecting port part.Further, spreading glass partition thing is also bonding with above-mentioned TFT substrate 102 and opposed substrate 103 by above-mentioned encapsulant 106, and making formed liquid crystal board gap is 13 μ m.
Then, between TFT substrate 102 and opposed substrate 103, import the liquid crystal polymer mixed solution that comprises liquid crystal and ultraviolet hardening macromolecule dispersion material PNM201 with vacuum impregnation.
Further, as shown in Figure 8, for after blocking near the encapsulant 106 non-display area 202 and encapsulant 106 and having disposed ultraviolet reflection plate 210,210, with with the ultraviolet generator (trade name: UVA702-IMNSC-BB01 of extra-high-pressure mercury vapour lamp as light source, ウ シ オ motor system) 211, shine the 1st ultraviolet ray 60 seconds from opposed substrate 103 sides.Therefore, the high molecular polymerization in the zone beyond the zone of blocking by ultraviolet reflection plate 210,210, and liquid crystal is separated with macromolecule resin matrix phase.At this moment, the temperature of liquid crystal board (polymerization temperature) is set at 19 ℃ with circulation thermostat with the surface temperature of liquid crystal board.In addition, measure ultraviolet intensity, and be set and be 100mW/cm with ultraviolet illuminometer UV-M02 (オ-Network make made) 2
Then, ultraviolet reflection plate 210,210 is removed, to whole surface irradiation the 2nd ultraviolet ray of liquid crystal board 60 seconds.Above-mentioned the 2nd ultraviolet irradiation intensity is set at 500mW/cm 2Therefore, make the macromolecule in the non-display area 202 disperse the material polymerization, and liquid crystal is separated with macromolecule resin matrix phase.As mentioned above, when to liquid crystal polymer mixed solution irradiation ultraviolet radiation, owing to make the ultraviolet irradiation intensity that is radiated at non-display area 202 greater than viewing area 201, so can control the form that exists of liquid crystal drop.That is,, then can make liquid crystal and macromolecular compound carry out phase further and separate as strengthening ultraviolet irradiation intensity, so, in non-display area 202, make liquid crystal drop 206 with independent and state that disperse exists respectively.On the other hand, in viewing area 201, liquid crystal drop 205, its part exists to be in contact with one another with the state that is connected.
When having shone by aforesaid mode when ultraviolet, the ultraviolet total exposure intensity that is radiated at non-display area 202 is 600mW/cm 2, and the ultraviolet total exposure intensity that is radiated at viewing area 201 is 500mW/cm 2Therefore, on the surface, be that the ultraviolet irradiation amount that is radiated on the non-display area 202 is bigger than the ultraviolet irradiation amount that is radiated on the viewing area 201.But in viewing area 201, in the stage that the 1st time ultraviolet ray irradiation finishes, liquid crystal separates with the phase of macromolecular compound and finishes.Therefore, although shine 500mW/cm again thereafter 2Ultraviolet ray, but do not react.So, in fact, should be on the ultraviolet irradiation amount when being separated, the exposure of non-display area 202 is big.
The structure of above-mentioned liquid crystal drop 205,206 is confirmed as follows.That is, will be bonding with encapsulant by a pair of substrate that glass constitutes, inject by the liquid crystal polymer mixed solution that constitutes with above-mentioned same constituent polymerization and make liquid crystal board under same polymerizing condition.And, on this liquid crystal board, do not form TFT etc.With any one substrate desquamation of made liquid crystal board and carried out the mensuration of liquid crystal drop particle diameter.In more detail, use the microscopic examination liquid crystal drop, and ask for the mean value of particle diameter with image-processing system.The result who observes shows that the mean grain size of the liquid crystal drop of viewing area is 1.2 μ m, and its part is interconnective shape.At this moment, the liquid crystal number percent that is present in the viewing area is 75%.On the other hand, the mean grain size of the liquid crystal drop of non-display area is less than 0.6 μ m, and liquid crystal drop is roughly separate shape.At this moment liquid crystal number percent is 68%.
Can infer from above situation, in the liquid crystal display cells of present embodiment, also the situation with said structure is the same, and the liquid crystal drop 205 of viewing area 201 is a part of interconnective structure, and the liquid crystal drop 206 of non-display area 202 is separate dispersed texture.
Then, made liquid crystal board is put into baking oven, carried out annealing in process.Treatment conditions are 80 ℃, 10 hours.Then, cool to room temperature, and with microscopic examination the be full of cracks generation state of macromolecule resin matrix.Consequently, confirmed near the macromolecule resin matrix the encapsulant 106, not chap, on viewing area 201, also do not taken place to show inhomogeneous.
In addition, carrying out the 2nd time when irradiation ultraviolet ray, carrying out comprehensive irradiation after ultraviolet reflection plate 210 is removed, but at this moment also can shine again after with the regional occlusion suitable that shone for the 1st time with ultraviolet reflection plate 210 with the viewing area.Therefore, block, have the effect of inhibition because of the decomposition of the liquid crystal in the UV-induced viewing area 201 etc. by the above-mentioned zone that the 1st time was shone.
In addition, ultraviolet irradiation intensity also can be controlled by the intensity that changes illuminator.Specifically, for example, under the situation that adopts extra-high-pressure mercury vapour lamp, high-pressure mercury-vapor lamp etc., because the ultraviolet wavelength peak value is in 365nm, the ultraviolet irradiation intensity of its visible region is little, thus can suppress the decomposition of liquid crystal, and can prevent the reduction of reliability.On the other hand, when adopting metal halide lamp, even in the visible region, this lamp also has certain intensity, so, exist the problem that makes reliability aspects such as liquid crystal decomposition.
[the 3rd embodiment]

Therefore, the macromolecule precursor polymeric in the zone beyond the zone that will block by ultraviolet reflection plate 210,210, and liquid crystal is separated with macromolecule resin matrix phase.Consequently, in viewing area 201, become the interconnective shape of a part of liquid crystal drop.And in non-display area 202, since uncured, so be the liquid condition that liquid crystal mixes with macromolecular compound.Here, the temperature of liquid crystal board (polymerization temperature) is set at 19 ℃ with circulation thermostat with the surface temperature of liquid crystal board.
Then, made liquid crystal board is put into baking oven, carried out annealing in process.Treatment conditions are 80 ℃, 10 hours.Then, cool to room temperature, and with microscopic examination the be full of cracks generation state of macromolecule resin matrix.Consequently, confirmed not chap near the macromolecule resin matrix the encapsulant 106, it is inhomogeneous that demonstration also takes place on viewing area 201, thereby obtained good display panel.
[the 4th embodiment]
According to Figure 11 the 4th embodiment of the present invention is described as follows.Have the inscape of said function for liquid crystal display cells, be marked with prosign and it describe in detail is omitted with above-mentioned the 1st embodiment～the 3rd embodiment.
The liquid crystal display cells of present embodiment is compared with the structure of the liquid crystal display cells of above-mentioned the 1st embodiment, the 2nd embodiment or the 3rd embodiment, and its difference is, the sidepiece clearance layer that does not have high molecule liquid crystal complex layer is set in non-display area.
In more detail, as shown in figure 11, mainly be only high molecule liquid crystal complex layer 400 to be set in viewing area 201, and make above-mentioned sidepiece clearance layer 412 be vacuum state.Therefore, owing in the zone that be full of cracks takes place, not have macromolecule resin and liquid crystal, so can prevent the generation of chapping fully.In addition, above-mentioned non-display area 202, being not limited to is the situation of vacuum state.Also can the filling air, other gases such as nitrogen, argon gas or macromolecular compound etc.And when adopting above-mentioned air, this air can adopt the low dry air of humidity, but preferably little to the pollution of liquid crystal etc.
In addition, above-mentioned viewing area 201 also can be to make macromolecule resin matrix form three-dimensional netted and so that liquid crystal remains on the structure that the state in this net disperses.In addition, though can also be that contrast reduction liquid crystal drop is separate structure of disperseing.
In the 2nd～the 4th embodiment, in with the layer of dispersed liquid crystal in macromolecule, make near the structure the encapsulant 106 different with the structure of other parts, but under the situation of this structure, is not satisfied with near the of encapsulant 106 as carrying out the zone that image shows, image shows near the zones beyond preferably adopting the encapsulant 106.
(embodiment 4-1)
The liquid crystal display cells of present embodiment 4-1 is corresponding to above-mentioned the 4th embodiment.Above-mentioned liquid crystal display cells is made by method shown below.
At first, the mode with same with the foregoing description 1 by vacuum evaporation and etching and processing, forms pixel capacitors 105, source electrode line 108, dielectric film 109 etc. on the following substrate 111 that is made of glass, constituted TFT substrate 102.Further, behind printing オ プ ト マ-AL5417 on the following substrate 111, be solidified to form dielectric film 109 with print process with baking oven for heating.On the other hand, on last substrate 112,, constituted opposed substrate 103 to form opposite electrode 107, dielectric film 109 etc. with above-mentioned same method.Then, on above-mentioned TFT substrate 102, printing heat curing type encapsulant is as encapsulant 106, makes its coating be shaped as frame shape pattern in the leaving certain gaps uncovered by the economic plan of liquid crystal injecting port part.
Then, on the zone that comprises viewing area 201, with the drip liquid crystal polymer mixed solution that liquid crystal and ultraviolet hardening macromolecule disperse material PNM201 that contains of necessary amount of nozzle.Here, as the method for configuration macromolecular material on viewing area 201, except that above-mentioned, also can cover and be coated with non-display area 202 with spinner.In addition, can also adopt general printing processes such as cylinder.
Further, spreading glass partition thing is also bonding with above-mentioned TFT substrate 102 and opposed substrate 103 by above-mentioned encapsulant 106, and making the liquid crystal board gap is 10 μ m, thereby makes liquid crystal board.Here, make the inner peripheral surface of encapsulant 106 and being spaced apart about 3mm of viewing area 201.In addition, because TFT substrate 102 and opposed substrate 103 bonding operations are carried out in air, so air in filling near the non-display area 202 encapsulant 106.
Then, use, from opposed substrate 103 side irradiation ultraviolet radiations 60 seconds the ultraviolet generator 211 of extra-high-pressure mercury vapour lamp as light source.Therefore, make the macromolecule precursor polymeric in the viewing area 201, and liquid crystal is separated with the macromolecular compound phase.At this moment, the temperature of liquid crystal board (polymerization temperature) is set at 20 ℃ with circulation thermostat.In addition, ultraviolet irradiation intensity is set at 80mW/cm 2
At this moment, find that filling air and formed high molecule liquid crystal complex layer 400 in viewing area 201 in sidepiece clearance layer 412 behind the observation liquid crystal board.
At last, with sealing encapsulant (trade name: TB3026, ス リ-bonding agent (company limited) system) inlet has been carried out sealing processing.
Further, with microscopic examination the liquid crystal board of making, confirmed not chap near the non-display area 202 encapsulant 106.Then, under 80 ℃, liquid crystal board carried out 10 hours annealing with baking oven, and cool to room temperature.Consequently, near encapsulant 106, owing to do not have high molecule liquid crystal complex layer, so made the liquid crystal display cells that does not chap thereby have good display characteristics.
(embodiment 4-2)
The liquid crystal display cells of present embodiment 4-2 is corresponding to above-mentioned the 4th embodiment.
The liquid crystal display cells difference of the liquid crystal display cells of present embodiment 4-2 and the foregoing description 4-1 is that non-display area 202 is not vacuum but is provided with polymer resin layer (with reference to Figure 12).
Above-mentioned liquid crystal display cells is made by method shown below.
At first, in the mode same,, constituted TFT substrate 102 forming pixel capacitors 105, source electrode line 108, dielectric film 109 etc. on the substrate 111 down with the foregoing description 4-1.On the other hand, on last substrate 112,, constituted opposed substrate 103 to form opposite electrode 107, dielectric film 109 etc. with above-mentioned same method.Then, on above-mentioned TFT substrate 102, printing heat curing type encapsulant is as encapsulant 106, makes its coating be shaped as frame shape pattern in the leaving certain gaps uncovered by the economic plan of liquid crystal injecting port part.
Polymerizable monomer with 90% (2-ethyl propylene acid esters), 9% oligomer (trade name: PVC ス コ-ト 828, Osaka organic chemistry industry system), 1% polymerization initiator (trade name: benzyltrimethyl ketone acetal, Japan's chemical drug system) mixes, and make polymeric composition A.Further, make 20% this polymeric composition A and 80% the mixed polymeric composition B of liquid crystal material TL205 (メ Le Network corporate system).
Then, on the zone that comprises viewing area 201, with the drip polymeric composition B of necessary amount of nozzle.Further, with the nozzle polymeric composition A that drips, then, that TFT substrate 102 and opposed substrate 103 is bonding on non-display area 202.
At last, according to the method identical,, and make the liquid crystal display cells of present embodiment to the liquid crystal board irradiation ultraviolet radiation with embodiment 4.
Find after observing above-mentioned liquid crystal display cells that viewing area 201 is that liquid crystal drop disperses to remain on the high polymer dispersed liquid crystal in the resin, non-display area 202 is the structures that only have the macromolecule resin after the polymerization.That is, formed polymer resin layer 521.
Then, made liquid crystal board is put into baking oven, carried out annealing in process.Treatment conditions are 80 ℃, 10 hours.Then, cool to room temperature, and with microscopic examination the be full of cracks generation state of macromolecule resin matrix.Consequently, confirmed not chap near the macromolecule resin matrix the encapsulant 106, it is inhomogeneous that demonstration also takes place on viewing area 201, thereby obtained good display panel.
The reason that obtains The above results is, only has macromolecule resin near encapsulant 106, so, compare with the situation that has liquid crystal drop, the fracture strength of last substrate 111 or the distortion etc. of substrate 112 is down increased.
In addition, because near the polymer resin layer 521 the encapsulant 106 has identical material with the macromolecule resin matrix of high molecule liquid crystal complex layer 400, so this high molecule liquid crystal complex layer 400 is also not obvious with the boundary line of polymer resin layer 521.
As above-mentioned polymer resin layer 521, can be ultraviolet curing resin, also can be the thermohardening type resin.Ultraviolet curing resin, thus so long as contain the macromolecule resin that polymerization initiator etc. can solidify get final product under ultraviolet ray, do special the qualification, can adopt existing well-known all kinds.That is, can obtain the good demonstration of on this polymer resin layer 521, not chapping.In addition, when irradiation ultraviolet radiation, as make non-display area 202 after viewing area 201, begin polymerization, then have the more unconspicuous effect of boundary line that makes polymer resin layer 521 and high molecule liquid crystal complex layer 400.
[the 5th embodiment]
According to Figure 13～Figure 17, the 5th embodiment of the present invention is described as follows.Have the inscape of said function for liquid crystal display cells, be marked with prosign and it describe in detail is omitted with above-mentioned the 1st embodiment～the 4th embodiment.
The liquid crystal display cells of present embodiment, compare with the structure of the liquid crystal display cells of above-mentioned the 1st embodiment～the 4th embodiment, its difference is, makes the liquid crystal drop particle diameter (with reference to Figure 13) of the liquid crystal drop particle diameter of the non-display area in the high molecule liquid crystal complex layer greater than the viewing area.
In more detail, as Figure 14 and shown in Figure 15, the liquid crystal drop 501 of viewing area 201, its part exists with interconnective state, and the liquid crystal drop 502 of non-display area 202, its major part exists with interconnective state.Therefore, the particle diameter of liquid crystal drop 501 is obviously little than the particle diameter of liquid crystal drop 502.In addition, as shown in figure 16,, wide than the connecting portion 504 that liquid crystal drop 501 is linked together with the connecting portion 503 that liquid crystal drop 501 is connected with liquid crystal drop 502.Therefore, even high molecule liquid crystal complex layer 500 expands or shrinks, but owing to liquid crystal is easy to flow in connecting portion 503, so can prevent near encapsulant 106, to chap.In addition, above-mentioned non-display area 202 is pressed frame shape zone and is formed, and the inner peripheral surface of its width self-sealing material 106 rises and is at least 1, more than the 0mm.
In other words, even because of liquid crystal display cells heating being made liquid crystal expand, but because of the particle diameter of liquid crystal drop 502 structurally greatly and connecting portion 503 also wide, so do not hinder this flow of liquid crystal.On the other hand, even sharply increase because of thereby liquid crystal board cooling makes by this polymeric resin matrix confrontation liquid crystal applied pressure the volumetric contraction of macromolecule resin matrix, but based on above-mentioned same reason, do not hinder flow of liquid crystal yet.Therefore, even owing to long-time placement the at high temperature makes liquid crystal concentrate on inside, but when at cool to room temperature thereafter, this liquid crystal is still can be at an easy rate mobile and return non-display area 202 between liquid crystal drop.Therefore, can prevent the generation of chapping.
In addition, the same with above-mentioned the 1st embodiment or the 2nd embodiment, the particle diameter of the liquid crystal drop 501 of viewing area 201 preferably is about 1.2 μ m.On the other hand, in non-display area 202, then will suppress flow of liquid crystal, thereby be easy to chap about 1.2 μ m of enough gains if can obtain.And, because near the zone the encapsulant 106 is not included in viewing area 201, so the particle diameter of liquid crystal drop 502 not necessarily must be an optimum grain-diameter.Therefore, consider, make the interval of near the particle diameter of the liquid crystal drop 502 the encapsulant 106 or grid bigger than viewing area 201 from above situation, near this point that when guaranteeing contrast, can prevent to take place to chap the encapsulant 106, more effective.
As the high molecule liquid crystal complex layer 500 of the main composition key element of present embodiment liquid crystal display cells, can form by the method for the following stated.
Figure 17 is the sectional drawing that is used to illustrate above-mentioned liquid crystal display cells manufacture method.At first, it is bonding to be respectively equipped with the TFT substrate 102 or the opposed substrate 103 of pixel capacitors 105 and opposite electrode 107 in advance with encapsulant 106.Further, between above-mentioned TFT substrate 102 and opposed substrate 103, injecting with uncured resin monomer such as ultraviolet curing resin and liquid crystal material is the liquid crystal polymer potpourri of main material.Then, to above-mentioned liquid crystal polymer potpourri irradiation ultraviolet radiation, what make that viewing area 201 separates with the phase of non-display area 202 carries out the degree difference.Specifically, to viewing area 201 irradiations the 1st ultraviolet ray, and to non-display area 201 irradiations 2nd ultraviolet ray littler than above-mentioned the 1st ultraviolet irradiation intensity.Thus, phase is separated in above-mentioned viewing area 201, and to carry out degree big, so the particle diameter of liquid crystal drop 502 diminishes.On the other hand, in non-display area 202, phase is separated, and to carry out degree littler than viewing area 201, so that the particle diameter of liquid crystal drop 501 becomes is big.By above step, form high molecule liquid crystal complex layer 500.In addition, the width that makes non-display area 202 is that the reason of 1.0mm is, always can be subjected to from the influence of the light of back side retroeflection when for example shining the 1st ultraviolet ray etc., thereby be difficult to make the area of non-display area 202 littler than this.
Here, in above-mentioned the 2nd embodiment, the 2nd ultraviolet irradiation is to have carried out comprehensive irradiation after ultraviolet reflection plate 210 is removed, and shines after block in the 1st ultraviolet zone (being equivalent to viewing area 201) but at this moment also can will shine with ultraviolet reflection plate 210.Therefore, when the liquid crystal to viewing area 201 shone for the 2nd when ultraviolet ray, have the effect of inhibition because of the decomposition of UV-induced liquid crystal etc.
In addition,, adopted the ultraviolet reflection plate that ultraviolet ray is reflected as blocking ultraviolet device, but except that above-mentioned so long as have and block ultraviolet effect and get final product, do special the qualification.That is, as blocking ultraviolet device, absorption-type, reflection-type can.But if absorption-type, then temperature will rise when irradiation ultraviolet radiation, so, compare with the situation of reflection-type, must control polymerization temperature well.
Further, the radical occlusion device during irradiation ultraviolet radiation also can make its relative position unanimity in the configuration up and down of liquid crystal board.In addition, can also block the sidepiece of liquid crystal board with photo-shield strip.Therefore, can block from retroreflection light behind, and can carry out the phase detachment process of liquid crystal and macromolecular compound equably, thus the uniform liquid crystal boards such as particle diameter of making liquid crystal drop.
(embodiment 5)
The liquid crystal display cells of present embodiment 5 is corresponding to above-mentioned the 5th embodiment.Above-mentioned liquid crystal display cells is made by method shown below.At first, the same with above-mentioned the 2nd embodiment, forming pixel capacitors 105, source electrode line 108, dielectric film 109 etc. on the substrate 111 down, constituted TFT substrate 102.On the other hand, on last substrate 112, form opposite electrode 107, dielectric film 109 etc., constituted opposed substrate 103 with method same as described above.Then, on above-mentioned TFT substrate 102, the frame shape pattern of printing and sealing material 106, then, that TFT substrate 102 and opposed substrate 103 is bonding.
Further, the same with the 2nd embodiment, block non-display area 202 and encapsulant 106 near the encapsulant 106 with ultraviolet reflection plate 210,210, make the surface temperature of liquid crystal board remain on 19 ℃, and be 100mW/cm from the exposure intensity that opposed substrate 103 sides have been shone 60 seconds 2The 1st ultraviolet ray.Therefore, make the macromolecule precursor polymeric in the zone in addition, zone of being blocked, and liquid crystal is separated with macromolecule resin matrix phase by ultraviolet reflection plate 210,210.Consequently, in viewing area 201, become the interconnective shape of a part of liquid crystal drop.Here, the temperature of liquid crystal board (polymerization temperature) is set at 19 ℃ with circulation thermostat with the surface temperature of this liquid crystal board.
Then, ultraviolet reflection plate 210,210 is removed, to whole surface irradiation the 2nd ultraviolet ray of liquid crystal board 240 seconds.Above-mentioned the 2nd ultraviolet irradiation intensity is set at 10mW/cm 2Like this, separate with the phase of macromolecular compound by reducing ultraviolet irradiation intensity inhibition liquid crystal, so the high molecular degree of polymerization is also little.Therefore, the particle diameter of the liquid crystal drop 502 of non-display area 202 is greater than the particle diameter of the liquid crystal drop 501 of viewing area 201, and the shape of liquid crystal drop 502 is existed with its most of interconnective state.On the other hand, in viewing area 201,, be in contact with one another with the state that is connected with its part and exist than the little liquid crystal drop 501 of the particle diameter of liquid crystal drop 502.
The structure of above-mentioned liquid crystal drop 501,502 is confirmed as follows.That is, will be bonding with encapsulant by a pair of substrate that glass constitutes, inject by the liquid crystal polymer mixed solution that constitutes with above-mentioned same constituent polymerization and make liquid crystal board under same polymerizing condition.And, on this liquid crystal board, do not form TFT etc.With any one substrate desquamation of made liquid crystal board and carried out the mensuration of liquid crystal drop particle diameter.In more detail, use the microscopic examination liquid crystal drop, and ask for the mean value of particle diameter with image-processing system.The result who observes shows that the particle diameter of liquid crystal drop is 1.2 μ m, and is a part of interconnective shape.On the other hand, the particle diameter of the liquid crystal drop of non-display area 202 is greater than 2 μ m, and is most of interconnective shape.The liquid crystal number percent of non-display area 202 at this moment is 80%.
Can infer from above situation, in the liquid crystal display cells of present embodiment, also the situation with said structure is the same, and the liquid crystal drop 501 of viewing area 201 is a part of interconnective structure, and the liquid crystal drop 502 of non-display area 202 is most of interconnective structure.
Then, made liquid crystal board is put into baking oven, carried out annealing in process.Treatment conditions are 80 ℃, 10 hours.Then, cool to room temperature, and with microscopic examination the be full of cracks generation state of macromolecule resin matrix.Consequently, confirmed near the macromolecule resin matrix the encapsulant 106, not chap, on viewing area 201, also do not taken place to show inhomogeneous.
Discoveries such as present inventor, ultraviolet irradiation intensity is more little, and then polymerization speed is low more, and the particle diameter of liquid crystal drop becomes big.Therefore, if the 2nd ultraviolet irradiation intensity that is radiated at non-display area 202 is less than the 1st ultraviolet irradiation intensity that is radiated at viewing area 201, then near the particle diameter of the liquid crystal drop the encapsulant 106 will be bigger than viewing area 201, therefore can obtain said structure.
Here, by changing the 1st and the 2nd ultraviolet irradiation intensity, checked the demonstration degree of irregularity that causes because of be full of cracks, the gain of viewing area 201, the particle diameter of liquid crystal drop etc.Check result is listed in following table 2 and table 3.The metewand that table 2 is listed is ◎ when contrast is 250, be zero when contrast is 100, be Δ when contrast is 80, when contrast is 30 for *.The result that table 3 is listed, expression makes the 1st ultraviolet irradiation intensity change into 10,20,50,70,100,200,300,400 situation with respect to the value of the 2nd ultraviolet irradiation intensity.

For the contrast that makes liquid crystal board more than 100, must make gain below 2.5.For this reason, be radiated at the 1st ultraviolet irradiation intensity on the viewing area 201, consider, be preferably in 50mW/cm from the viewpoint of gain 2～400mW/cm 2Scope in.That is, as be replaced as the particle diameter of liquid crystal drop, then be equivalent in the scope of 0.8 μ m～1.4 μ m.On the other hand, for the demonstration of eliminating viewing area 201 inhomogeneous, near the non-display area 202 encapsulant 106, even liquid crystal also must be in the state that is easy to flow during the cooling in fail-test.For this reason, near the particle diameter of the liquid crystal drop the encapsulant 106 from the result of table 3, is preferably in more than the 1.8 μ m.For the 2nd ultraviolet irradiation intensity, this is equivalent to 20W/cm 2Below.

As liquid crystal, can adopt various liquid crystal such as near normal temperature, be mesomorphic state nematic liquid crystal, cholesteryl liquid crystal, smectic liquid crystal.These liquid crystal can use a kind, also can use mixing more than 2 kinds.In addition,,, do not do special the qualification, can adopt existing well-known all kinds as long as have transmitance as macromolecular compound.
As the clearance layer 606a and the sidepiece clearance layer 606b of the main composition key element of the liquid crystal display cells of present embodiment, be the fluidized bed that constitutes by air etc.Above-mentioned air is a low humidity, but preferably little to the pollution of liquid crystal display cells.In addition, in the present embodiment, also can adopt other gases such as nitrogen or argon gas.
Here, by aforesaid clearance layer 606a being set, can adding the function that prevents the shear stress that causes because of deflection etc.For example, when pushing outside the bottom surface of TFT substrate 601, deflection as shown in figure 20 will take place in liquid crystal display cells.But,, opposed substrate 602 is not contacted, with high molecule liquid crystal complex layer 605 so can prevent the generation of shear stress owing to form clearance layer 606a in a side of high molecule liquid crystal complex layer 605.Therefore, even the liquid crystal display cells deflection can not produce the different zone of scattering yet, thereby it is inhomogeneous to alleviate the demonstration of display panel.
In addition, in above-mentioned example,, also clearance layer 606a only can be arranged on the viewing area though clearance layer 606a is arranged on the whole zone that comprises the viewing area.As adopt this structure, then in the scope of viewing area, though from external action pressing force, in this scope, can not produce shear stress yet, thereby can not show inhomogeneous.On the other hand, though outside the viewing area, might produce shear stress, also inhomogeneous even if produced shear stress owing in the viewing area, not showing, so do not have any problem as liquid crystal display cells.Therefore, in the viewing area, can suppress at least to produce the different zone of light scattering, thereby it is inhomogeneous to alleviate the demonstration of display panel because of the effect of shear stress.
Above-mentioned sidepiece clearance layer 606b as mentioned above, is arranged on by the frame shape between the outer peripheral face of the inner peripheral surface of above-mentioned sealing material layer 615 and high molecule liquid crystal complex layer 605.Therefore, even carry out fail-test such as thermal shock, but owing near the encapsulant 615 that produces be full of cracks, do not have macromolecular compound and liquid crystal, so can fundamentally prevent the generation of this be full of cracks.Therefore, can prevent that the demonstration of the striated that produces because of this be full of cracks is inhomogeneous.Further, the destruction that can prevent shapes such as live width because of the formation pattern of sealing material layer 615 broadens in the horizontal caused sealing material of infiltration and the molten of high molecule liquid crystal complex layer that sealing material layer 615 takes place mixes.Accuracy requirement when in addition, printing sealing material 615 also can obtain relaxing.
Show for making liquid crystal display cells of the present invention carry out colour, for example, as shown in figure 21, only need between opposed substrate 602 and opposite electrode 604, colour filter 631 to be set and get final product.Above-mentioned colour filter 631, structurally comprise color material film R, G, B and black matrix 632 ... here, we find, by clearance layer 606a is set, can also suppress the color material film R of colour filter 631, the generation and the black matrix 632 of the colour mixture between G, the B ... the light loss that causes.
For example, the color material film G that is conceived to colour filter 631 discusses.As shown in figure 22, as by back of the body irradiation etc. from TFT substrate 601 side irradiates lights, then when incident light incides high molecule liquid crystal complex layer 605, be scattered.Here, when the refractive index n of opposed substrate 602 gRefractive index n with air AirThe pass be n g＞n AirThe time, make the refractive index n of high molecule liquid crystal complex layer 605 pRefractive index n with clearance layer 606a xThe pass be
n p＞n x(1) further, make the refractive index n of TFT substrate 601 gRefractive index n with clearance layer 606a xThe pass be
n g＞n x(2) in this case, from following formula (1) as can be seen, the part of the scattered light after being scattered when inciding high molecule liquid crystal complex layer 605, total reflection on the border of high molecule liquid crystal complex layer 605 and clearance layer 606a.Here, said a part of scattered light by this border total reflection comprises light that might incide adjacent color material film B by total reflection on opposed substrate 602 and airborne border indirectly and the light that is absorbed by black matrix 632.Therefore, owing to be provided with clearance layer 606a and high molecule liquid crystal complex layer 605, clearance layer 606a and TFT substrate 601 served as reasons the material that the refractive index of the relation that satisfies following formula (1) and (2) constitutes, so a part of scattered light that constitutes the colour mixture reason can be given first eliminating before it arrives colour filter 631, can reduce the light that is absorbed by black matrix 632 simultaneously.Consequently, can reduce the generation of colour mixture, and can improve the utilization ratio of light, thereby can make display panel become bright.
, the gap of above-mentioned clearance layer 606a must be set after the relation of considering with the pitch of the color material film R of colour filter 631, G, B.That is, as shown in figure 23, as to establish color material film R, G, B pitch separately be that the width of P (μ m), black matrix 632 is d (μ m), and then percentage of open area Op (%) is expressed from the next.
Op (%)=100 * (P-d) 2/ P 2(3) here, for making percentage of open area, should satisfy following formula for example more than 40%.
Op (%)=100 * (P-d) 2/ P 2〉=40 ... (4) therefore, the relation of P and d is expressed from the next.
d≤P{1-(0.4) 1/2}????????????????????…(5)
On the other hand, as shown in figure 23, from the light of TFT substrate 601 side incidents under the situation after the scattering on the border of high molecule liquid crystal complex layer 605 and clearance layer 606a, establishing the angle that rectilinear propagation light become with scattered light is θ.In these cases, the gap L of clearance layer 606a (μ m) and above-mentioned rectilinear propagation light and scattered light are x=Ltan θ in the pass apart between x (μ m) of the point of arrival of colour filter 631.For preventing that scattered light is directly incident in the adjacent color material film, x is got final product in the formation scope of black matrix 632.That is, the relation that satisfies x≤d gets final product.Can get thus,
Ltan θ≤d ... (6) thus, can get from the relation of following formula (5) and (6),
Ltan θ≤P{1-(0.4) 1/2... (7) therefore, can set the gap of clearance layer 606a according to following formula.
L≤P{1-(0.4) 1/2}/tan θ ... (8) as by the gap of setting clearance layer 606a with upper type, can prevent that then the part of the light after the scattering on the border of high molecule liquid crystal complex layer 605 and clearance layer 606a from inciding in the adjacent color material film.Figure 24 illustrate the angle θ that is become with scattered light when rectilinear propagation light be 40,50,60 when spending the pitch P of color material film R, G, B and the relation of the gap L of clearance layer 606a.Common notebook personal computer or monitor etc., P is in 80～120 mu m ranges, even under the meticulousst situation, also about 30～50 μ m.Therefore, be 40% when above when making percentage of open area, need only gap L be set in the scope shown in Figure 24 according to the value of P and get final product.In addition, in the above description, having told about and having made percentage of open area is situation more than 40%, but the gap of clearance layer 606a can comparatively at random be set according to the value of the percentage of open area that sets.Therefore, above explanation also can be carried out same discussion to other the value of percentage of open area.
