While solving the problem by setting the liquid crystal layer thickness adjusting film in the pixel forming region, but the laminated construction of the counter electrode and photomask is blocked, and bring bad display which is due to the resisitance increasing of counter electrodes. Thereby the present invention sets a light-shielding film on the internal surface of the front substrate in pixel region, and sets the thickness adjusting film to cover the light-shielding film, and has a contact hole, wherein the counter electrode is provided to oppose to the pixel electrode, and electrically connected to the light shielding film via the contact hole.
Description
Technical field
The present invention relates to liquid crystal display cells, more particularly, relate to the liquid crystal display cells that has used field-sequential mode.
Background technology
In recent years, the field preface that does not need color filter is made progress with the exploitation of liquid crystal display cells.In the field-sequential mode, owing to carry out the colour demonstration by switching the RGB three-color light source at a high speed, thereby do not use the color filter that is used for common liquid crystal display cells, use the subtend substrate of the counter electrode that possesses the photomask that constitutes by Cr film etc. and constitute by nesa coating mutually on the contrary.At this, counter electrode extends to outside the pixel region, is electrically connected with electrode on the array base palte and wiring.
Field preface liquid crystal display cells is corresponding for seeking high speed, and uses the strong medium liquid crystal as the liquid crystal of enclosing between two substrates that constitute liquid crystal display cells.At this, in order to enclose liquid crystal, known have a following method, for example liquid crystal is dripped on the substrate, and at the periphery coating encapsulant of above-mentioned two substrates, and adhesive base plate, afterwards, make sealing material curing by heat and light, liquid crystal is enclosed.When using the strong medium liquid crystal as liquid crystal material, the scope of thickness for being best suited for of the liquid crystal layer between two substrates of formation liquid crystal display cells than narrow 1～3 μ m of regular situation.Therefore, also there is configuration to be used for the thickness of the liquid crystal layer in the pixel region is kept the situation of uniform liner.
But, for there is following problem in the thickness that makes liquid crystal layer than regular situation is narrow.As mentioned above, in operation, if the space between the substrate of this moment is narrow with two base plate bondings, then be clipped in the encapsulant diffusion between the substrate, and the unhardened resin of encapsulant etc. is diffused into liquid crystal and encloses the zone, therefore produces liquid crystal pollution, and demonstration is bad until occurring.Then can not produce this problem if improve the viscosity of encapsulant, but in this case, encapsulant can not be pressed off fully when adhesive base plate, therefore, the space of panel periphery portion enlarges.Therefore, exist in the periphery of pixel region and the uneven thickness that liquid crystal layer appears in central portion, and cause the problem (for example, with reference to Patent Document 1) that shows color spot.
For addressing these problems, known have following such technology, by the encapsulant area surrounded that is coated on subtend substrate periphery portion, regulate film and form counter electrode thereon by the thickness of liquid crystal layer that is provided for regulating thickness of liquid crystal layer, and take into account structure and the good sclerosis the two (for example with reference to Patent Document 2) of encapsulant that the thickness of liquid crystal layer in the pixel region is dwindled.
Patent Document 1: the spy opens 2003-280007 communique (Fig. 6)
Patent Document 2: the spy opens 2004-264606 communique (Fig. 4)
According to said method, can avoid the problem of sealing material curing, can reduce simultaneously the thickness of the liquid crystal layer of the pixel region that encapsulant surrounds, but the following problem that exists this method to cause.That is, when adopting said method, need on the subtend substrate, between photomask and counter electrode, form the dielectric film of regulating film as thickness of liquid crystal layer.This be because, counter electrode is the electrode that is used for liquid crystal applied voltages, it is desirable to, if remove oriented film, then it is the superiors' (apart from glass substrate layers farthest), in addition, and from considering with the adhesion of bottom and the optimization aspect of anti-reflection effect, it is desirable to, photomask forms on glass substrate.
And in this structure, above-mentioned problem is solved, but has produced other such unfavorable condition of lateral cross talk.Originally the ratio resistance that was used for the nesa coating of counter electrode only is about 0.00002 Ω cm, and thickness is about 0.1 μ m, and therefore, the resistance of counter electrode also can be described as low resistance.Therefore, at the position that the connecting portion that is connected with array base palte outside pixel region leaves, be near the central authorities of pixel region, and array base palte between applied the resistance components of counter electrode self, thereby it is bad to be easy to generate the such demonstration of lateral cross talk.But the nesa coating of common subtend substrate is by stacked the forming of low-resistance metal film as photomask, therefore, can suppress to be increased and the lateral cross talk that causes is bad by resistance components.
Yet, according to above-mentioned structure, because hindered the counter electrode in the pixel region and the stepped construction of photomask as the formation of the dielectric film in the pixel region of this solution, therefore, low-resistance metal film of above-mentioned photomask can not be made sufficient contribution to the electric conductivity of counter electrode.Therefore, counter electrode becomes high resistance, causes that lateral cross talk is bad.
Summary of the invention
The invention provides a kind of liquid crystal display cells, form in the sealing of carrying out the pixel region periphery well, and have in the liquid crystal display cells of structure of the thickness of liquid crystal layer that reduces pixel region, it is bad to suppress above-mentioned lateral cross talk, and has good display characteristic.
The invention provides a kind of liquid crystal display cells, encapsulant by utilizing the periphery outside being formed at pixel region is with two base plate bondings, the liquid crystal of portion's inclosure within it forms, it is characterized in that, one of them of these two substrates is the subtend substrate, this subtend substrate possesses: the photomask that contains the metal film that forms on the transparent insulating substrate, the thickness of liquid crystal layer that covers this photomask is regulated film, and regulate the counter electrode that the nesa coating that forms on the film constitutes by above-mentioned thickness of liquid crystal layer, the above-mentioned thickness of liquid crystal layer in pixel region is regulated and is formed with at least one on the film and is used for contact hole that counter electrode is connected with photomask.
Liquid crystal display cells of the present invention has following structure: promptly, in the pixel region of subtend substrate, form after the dielectric film, in pixel region, form the connecting portion that the nesa coating with counter electrode is connected with photomask, reduce the structure of the thickness of the liquid crystal layer in the pixel region thus, and realized that no liquid crystal pollutes, no peripheral space is bad, the effect with good display characteristic of no lateral cross talk.

Secondly, TFT and the pixel electrode of being located at metacoxal plate 24 inner faces described.The planimetric map that Fig. 3 (1) expression is seen from the inner face of the metacoxal plate 24 that is formed with TFT.And, the sectional view of the metacoxal plate 24 at the position shown in the C-C line in Fig. 3 (2) presentation graphs 3 (1).With reference to Fig. 3 (1), (2), the TFT22 that is located at metacoxal plate 24 inner faces by public CS electrode wiring 12 on the real estate that is formed at metacoxal plate 24 and grid wiring 8, cover transparent gate insulating film 14 that the roughly whole zone at substrate of this grid wiring 8 forms, form at the i N-type semiconductor N film 9 that forms with grid wiring 8 subtends on the gate insulating film 14, the source electrode 10 that on i N-type semiconductor N film 9, forms and drain electrode 11, the passivating film 15 that covers i N-type semiconductor N film 9 and source electrode 10, drain electrode 11 via n N-type semiconductor N film 20.On passivating film 15, be provided with TFT contact hole 12.A plurality of pixel electrode 21 is made of nesa coatings such as ITO, and is formed on the passivating film 15, is connected with drain electrode 11 corresponding to the TFT22 of its pixel electrode 21 via TFT contact hole 12 in the distolateral end of one.And then form oriented film 17, make it cover TFT22 and passivating film 15.In addition, on the grid wiring 8 on the F-F line of Fig. 3 (1), be formed with column liner 6.In addition, as described later, be formed with contact hole 7 (not shown) being positioned on the subtend substrate (prebasal plate 23) on the grid wiring 8 on the E-E line of Fig. 3 (1).
Secondly, prebasal plate 23 is described.At first, the planimetric map of the prebasal plate 23 seen from inner face of Fig. 4 (1) expression.And then the sectional view at position shown in the D-D line in Fig. 4 (2) presentation graphs 4 (1).Among Fig. 4 (1), on the photomask 2 of the rectangular configuration of peristome 2a that is cut to the essentially rectangular shape that will be corresponding with the pixel electrode 21 on the metacoxal plate 24, shown in Fig. 4 (2), covering is regulated film 3 by the thickness of liquid crystal layer that SiNx film etc. constitutes, and then regulates the ITO film 4 that is provided with on the film 3 as the transparent conductivity of counter electrode at thickness of liquid crystal layer.ITO film 4 is electrically connected with above-mentioned photomask 2 via the contact hole of being located on the thickness of liquid crystal layer adjusting film 37.The pattern of photomask 2 becomes the shape that connects continuously outside the zone of peristome 2a.On ITO film 4, be formed with the column liner 6 that constitutes by photosensitive resin film.At this, if column liner 6 is overlapping with contact hole 7, then be difficult to the thickness of liquid crystal layer is kept evenly, therefore, shown in for example Fig. 4 (1), dispose like that, can be or not both are overlapping and form yet.And then coating is formed with oriented film 17 thereon.
Secondly, describe with reference to the method for making of Fig. 5 (1)～(5) the embodiment of the prebasal plate 23 that becomes feature of the present invention.At this, Fig. 5 (1)～(5) are the process profiles that is equivalent to the position of Fig. 4 (2).At first, CrOx, the Cr of thickness 150nm of continuous film forming thickness 10nm on transparent glass insulation substrate 1 such as the middle use of Fig. 5 (1) splash method after carrying out photomechanics, carry out etching, resist lift-off processing, form the pattern of photomask 2.In addition,, improve shaded effect, and also can use chromium nitride (CrNx) replaced C r, constitute the stepped construction of CrOx and CrNx for improving the density of photomask.Under this situation, compare, can obtain sufficient shaded effect with thin thickness with Cr.
Afterwards, in Fig. 5 (2), the SiNx (silicon nitride) of film forming thickness 700nm after having carried out the photomechanical production operation, carries out etching, resist lift-off processing, forms thickness of liquid crystal layer and regulates film 3 and contact hole 7.At this moment, shown in Fig. 2 (2), also the SiNx film of positive bottom that forms the position of encapsulant 18 can be removed and form recess 5.
Secondly, in Fig. 5 (3), film forming on whole such as use splash method becomes the ITO film 4 of counter electrode.At this moment, by via contact hole 7 with photomask 2 and 4 conductings of ITO film, thereby can reduce the resistance of counter electrode.At this, further increase owing to will connect the area of the contact hole 7 of photomask 2 and ITO film 4, all remove so for example also the thickness of liquid crystal layer on the photomask 2 can be regulated film 3, but exist etching period to increase and the low problem of productivity in this case.On the other hand,, contact hole 7 is being carried out under the situation of opening, having the effect that can suppress the needed area of etching and also can shorten etching period as present embodiment.In addition, in normal circumstances, for reducing the resistance of counter electrode, it is just enough only to form a plurality of contact holes 7.
Secondly, in Fig. 5 (4), the photosensitive resin film (not shown) about coating thickness 2 μ m after having carried out photomechanics, forms the column liner 6 with predetermined altitude (for example 1.5 μ m).On prebasal plate 23, thickness of liquid crystal layer in display pixel area is regulated and is formed one on the film 3 at least and be used for contact hole 7 that ITO film 4 and photomask 2 as counter electrode are electrically connected.At last, in Fig. 5 (5), coating also forms oriented film 17, makes the prebasal plate 23 of the embodiment of the invention.
More than metacoxal plate 24 and prebasal plate 23 are illustrated, but at this, in order clearly to use column liner 6 and encapsulant 18 to make the mutual subtend of two substrates and such as shown in Figures 1 and 2 position relation at the formation position of the contact hole 7 that forms on the prebasal plate 23 and the TFT22 that forms when bonding on metacoxal plate 24, Fig. 6 (1) is illustrated in the prebasal plate 23 at the position shown in the E-E line of Fig. 3 (1) and the sectional view of metacoxal plate 24.Shown in Fig. 3 (1) and Fig. 6 (1),, the TFT22 of relative metacoxal plate 24 upper surface shape inequalities with it goes up the contact hole 7 that forms prebasal plate 23, it would be better that formation is better on the smooth grid wiring 8 of apparent surface.Therefore, realized to carry out reliably the effect of orientation control that the milled processed of oriented film 7 is carried out.
Secondly, for the formation position of the column liner 6 on the clear and definite prebasal plate 23 and the position relation of TFT22, the prebasal plate 23 at the position shown in the F-F line of Fig. 6 (2) presentation graphs 3 (1) and the sectional view of metacoxal plate 24.Shown in Fig. 3 (1) and Fig. 6 (2), the column liner 6 of prebasal plate 23, the TFT22 of the surface configuration inequality of relative metacoxal plate 24 with it are gone up and formed, and be better not as good as forming on the grid wiring 8 of relatively flat.Therefore, realized easily to control the effect of thickness of liquid crystal layer.
And then, for the peristome 2a that forms on the photomask 2 on the clear and definite prebasal plate 23 and the position relation of the pixel electrode 21 on the metacoxal plate 24, the prebasal plate 23 at the position shown in the D-D line of Fig. 7 presentation graphs 4 (1) and the sectional view of metacoxal plate 24.The aforesaid encapsulant 18 of clamping between prebasal plate 23 and metacoxal plate 24, and column liner 6 contacts with the inner face of metacoxal plate 24, guarantees thickness of liquid crystal layer.Contact hole 7 and column liner 6 are to form in the nonoverlapping mode in each position.In addition, the position of the pixel electrode 21 on the metacoxal plate 24 forms in the position with respect to the peristome 2a of the photomask 2 of prebasal plate 23, simultaneously, (distance of the prebasal plate 23 of subtend and the inner face of metacoxal plate 24: the space) state of mainly regulating film 3 with reflection encapsulant 18 and thickness of liquid crystal layer is stipulated in the thickness d of the liquid crystal layer 16 of this position clamping.
Like this, the resistance of the counter electrode when being formed with the connecting portion that is electrically connected by contact hole 7 is measured, and with the situation that does not have contact hole 7, promptly the situation that only forms counter electrode by ITO film 4 is compared, and can obtain the low resistance value about 1/10～1/100.Like this, in order to obtain the resistance value lower, so preferably form photomask 2 than ITO film 4 low materials by resistance value than situation about only forming by ITO film 4.Between this prebasal plate 23 and metacoxal plate 24, form the encapsulant 18 of frame shape, by enclosing liquid crystal 16 and carrying out in the bonding liquid crystal display cells that forms, not only can not cause the bad of liquid crystal pollution and peripheral space, nor can cause that to increase the lateral cross talk demonstration that produces bad because of the resistance of counter electrode.
In addition, as long as thickness of liquid crystal layer in display pixel area is regulated and is formed one on the film 3 at least and be used for the contact hole 7 that is connected with photomask 2 as counter electrode ITO film 4, but shown in Fig. 4 (1), a plurality of pixel electrodes 21 in the more preferably corresponding display pixel area form at least more than one respectively.Under this situation, can make corresponding to the resistance value of each counter electrode 2,4 of each pixel electrode 21 much the same in the pixel display area territory, therefore, realize following these effects: can suppress the demonstration color spot that above-mentioned lateral cross talk shows that bad deviation causes, and can improve the bad boundary of demonstration.
Have, in the present embodiment, the SiNx film that forms 700nm thickness is regulated film 3 as liquid crystal layer, but is not limited thereto, and also can use other transparent dielectric film again, for example SiOx film etc.In addition, can also apply the resin molding that forms transparent insulating.Under this situation, owing to thickness of liquid crystal layer can be regulated the flattening surface of film 3, so can make at least with the thickness of the liquid crystal layer 16 in the zone of pixel electrode 21 subtends evenly, the while can similarly be handled the grinding of oriented film 17, therefore, realized improving the effect of display quality.And then, have photosensitive resin molding by use, thereby can use photomechanics and easily form contact hole 7.
In liquid crystal display cells of the present invention, regulate film 3 owing to be formed with thickness of liquid crystal layer, under the situation that the thickness of the liquid crystal layer in pixel region 19 is little even die, follow the liquid crystal pollution that encapsulant 18 forms and peripheral space is bad also can not produce, be not only this point and in pixel region 19, be provided with and regulate the contact hole 7 on the film 3 is connected ITO film 4 with photomask 2 position via being located at thickness of liquid crystal layer, therefore, realized following effect, promptly can not produce by the resistance of counter electrode and increase and the demonstration that causes is bad.
