Summary of the invention
Invent technical matters to be solved
As mentioned above, FFS mode liquid crystal display board is compared it with IPS mode liquid crystal display board and possessed following characteristics: its field angle is wider, contrast is higher, so and owing to have high-transmission rate and can realize showing brightly, even under the situation of using lower driven, owing to produced bigger maintenance electric capacity, just can realize good demonstration image quality thereupon so need not to be provided with in addition auxiliary capacitance line.
In such FFS mode liquid crystal display board, mainly be to be that main product is given birth to the transverse electric field with direction with the long limit of slit essence quadrature, be exactly to allow the slit part of pixel capacitors and the pixel capacitors part parallel all be under the state that makes the transmission of light shape when driving, just in time allow the slit part of pixel capacitors and the pixel capacitors parallel partly become and seem to be in the wire luminance with this slit with this slit with the transmittance state.On the other hand, short leg office in the end of having sealed the slit length direction, owing to be to be that main product is given birth to the transverse electric field with direction with minor face essence quadrature, so formed the state that on 2 directions, has all produced the transverse electric field, make the part of liquid crystal molecule become the state (detorsion (reverse twist)) that reverses to opposite direction, become the state that accurately to control transmitted light thus, might cause the brightness of viewing area to reduce.
But, for FFS mode liquid crystal display board 70C as shown in figure 13, be arranged on the slit 77C on the pixel capacitors 78C, be provided with the words of open end 77C ' part at place, one end, till the 77C ' of the open end of slit, all can produce normal electric field so and make liquid crystal cell reverse (owing to having realized edge (fringe) effect), so compare with the FFS mode liquid crystal display board of slit length direction both ends sealing, it shows that aperture area has enlarged the degree shown in size M among Figure 13 B, obtains a kind of FFS mode liquid crystal display board that becomes clear and show thus.
Yet a plurality of slits that are arranged on pixel capacitors are observed the generation of mixed color phenomenon sometimes in its place, slit one end is provided with the FFS mode liquid crystal display board 70C of open portion under the upwardly extending situation in side of intersecting with signal wire.The present application people is provided with above-mentioned such slit to pixel capacitors, and the reason that produces mixed color phenomenon in place, this slit one end is provided with the FFS mode liquid crystal display board of open portion carried out various researchs, and the result who these researchs is carried out analysis-by-synthesis has found that it is to be caused by following reason.
That is, as along shown in the sectional view Figure 13 B that comprises color filter substrate of Figure 13 AXIIIB-XIIIB line, its direction is positioned at the centre of pixel capacitors 78C Width physically along the center line 91 of the pixel capacitors 78C signal wire direction of each pixel.Yet, the distance of 77C '+M (M of Figure 13) till display width L2 is meant from the blind end that is arranged on slit 77C one side on the pixel capacitors 78C to the open end of opposite side is located in the position of moving to slit 77C open end 77C ' lateral deviation along the display centre line 92 of the viewing area of signal wire 74.In the prior art, owing to the be centered close to same position of end from about the chromatic filter of plane with signal wire 74, if, be Lm, Rm＞Lm so from the chromatic filter right-hand member to the distance the viewing area so be Rm from the chromatic filter left end to the distance the viewing area.
In addition, if the width of pixel capacitors 78C is L1, the center line 91 of pixel capacitors 78C and the distance, delta L between the display centre line 92 are as follows so:
ΔL＝(L1-L2)/2
Though the value of this Δ L according to the situation of manufacturing installation etc. and how much there are a little differences, is about 1～5 micron substantially.
So, in assembly array substrate AR and color filter substrate CF, because in the end of 77C ' side viewing area, the open end of slit 77C, so deviation leeway is that its value of Lm is less near pixel capacitors 78C.Conversely, at the distolateral place of the sealing of slit 77C since the viewing area away from the end of pixel capacitors 78C, so deviation leeway is that its value of Rm is bigger.Therefore, the open end 77C ' of slit 77C is under the situation on the right side, even also can not change though the CF substrate only has been offset some colors to the right, little by little, mixed color phenomenon also can take place owing to the viewing area is influenced in adjacent CF in case the CF substrate is offset left.And, in order to prevent mixed color phenomenon, though considering can be in color filter substrate CF, so-called black matrix is set between color adjacent one another are, if but consider the skew of substrate and be formed for preventing the black matrix of colour mixture, must increase the width of black matrix that can't transmitted ray so to a certain extent, the result who causes has like this sacrificed transmissivity.
The present invention is provided with slit at as described above exactly on its pixel capacitors, on this slit one end, be provided with the problem that produces mixed color phenomenon in the FFS mode liquid crystal display board of open portion, and a kind of technical scheme that addresses the above problem has been proposed, the object of the present invention is to provide a kind of LCD panel that becomes clear and show, it concerns by the position of checking pixel capacitors and chromatic filter avoids producing mixed color phenomenon.

Embodiment 1
The LCD panel of embodiment 1 has: array base palte, this array base palte have public electrode, be formed on dielectric film on the public electrode, be formed on the pixel capacitors on the dielectric film; Color filter substrate with colour filter; Liquid crystal layer by array base palte and color filter substrate clamping; This LCD panel is to drive liquid crystal layer by the electric field that produces between public electrode and the pixel capacitors, and it just is known as the LCD panel of so-called FFS pattern.Come the manufacturing process of the FFS mode liquid crystal display board 10A of this embodiment 1 is described with Fig. 1～Fig. 3.Wherein, Fig. 1 is the general view of 1 pixel of the color filter substrate of FFS mode liquid crystal display board of perspective representation embodiment 1 and alignment films, Fig. 2 is the sectional view along Fig. 1 II-II line, and Fig. 3 A is used for the electrode width of key diagram 1 and the general view of center line and display width and display centre line, and Fig. 3 B is the sectional view along the IIIB-IIIB line that comprises the color filter substrate of Fig. 3 A.
The FFS mode liquid crystal display board 10A of this embodiment 1 is the pairing equipment of FFS mode liquid crystal display board 70C with prior art shown in Figure 13.Promptly, the array substrate AR of the FFS mode liquid crystal display board 10A of this embodiment 1 is in the transparency carrier 11 whole surface range of glass substrate etc., for constituting the surperficial mode that is made of the Mo metal, the AL metal forms 2 tunic structures with the bottom, afterwards, form multi-strip scanning line 12 and many public wirings 13 that 2 layers of distribution by Mo/AL constitute by photolithography and etching method according to mode parallel to each other.Though aluminium has the little advantage of resistance value, conversely, it also exists perishable, and the shortcomings such as contact impedance height between the ITO, is exactly in order to improve the above-mentioned shortcoming of aluminium and cover molybdenum and form sandwich construction on aluminium.In addition, though what illustrate here is the pars intermedia that public wiring 13 is arranged on adjacent scanning lines 12, the position of this public wiring 13 is as long as between adjacent scanning lines 12, and its position can be selected arbitrarily.
Then, the whole surface ratio that has formed the transparency carrier of sweep trace 12 and public wiring 13 is covered as using the transparent conductivity layer that is made of ITO, formed public electrode 14 as the 1st electrode by photolithography and etching method equally.Though this public electrode 14 is electrically connected with public wiring 13, be not connected with sweep trace 12 and even gate electrode G.And, cover with the gate insulating film 15 that silicon nitride layer and even silicon oxide layer constitute on its whole surface, then, utilize the CVD method, such as after gate insulating film 14 whole surface range cover amorphous si-layer, same by photolithography and etching method, form the semiconductor layer 16 that formation is made of the a-Si layer in the zone at TFT.The zone of the sweep trace 12 of this semiconductor layer 16 position that forms forms the grid G of TFT.
Then in the whole surface range of the transparency carrier 11 that has formed semiconductor layer 16, cover conductive layer, form signal wire 17 and drain D by photolithography and etching method equally with Mo/Al/Mo3 layer structure.The source S part and the drain D part of this signal wire 17 are all overlapping with the surface portion of semiconductor layer 16.And the whole surface of this substrate covers by the dielectric film 18 that silicon nitride layer constitutes.
Then, with the dielectric film 18 of drain D correspondence position on form contact hole 19, make the part of drain D expose thus.Then, the transparent conductivity layer that on whole surface, constitutes by ITO such as covering, same by photolithography and etching method, such according to figure shown in Figure 1, formation has the pixel capacitors 21 of slit 20A on the dielectric film 18 of sweep trace 12 and 17 enclosing region of signal wire.The pixel capacitors 21 of the 2nd electrode is by constituting as the lower part: the band-like portions between the slit 20A that extends in parallel, place, an end in these band-like portions is broach shape part connected to one another, locates the maintenance extension state and also unconnected each other part in the other end of band-like portions.Therefore, the side of slit 20A is a blind end, and opposite side is open end 20A '.And as shown in Figure 1, slit 20A tilts with respect to sweep trace 12, and its vergence direction becomes the angle about 5～20 °.This pixel capacitors 21 is electrically connected with drain D by contact hole 19.
Then, by on this whole surface, forming the manufacture process that predetermined alignment films 24 is finished this array substrate AR.And so array substrate AR of making and the color filter substrate opposite disposed of making in addition with the encapsulant encapsulation, are injected liquid crystal around it then between two substrates, obtain the FFS mode liquid crystal display board 10A of embodiment 1 thus.And, the structure of color filter substrate will be as will using below that Fig. 3 is illustrated, except the center line of itself and each pixel corresponding colour filter 25AR, 25AG, 25AB is arranged to the display centre line 32 that moves to slit open end 20A ' lateral deviation from the center line 31 of pixel capacitors 21 consistent from the plane, all the other local schemes with prior art do not have substantive difference, and it specifies the Therefore, omited.
Shown in Fig. 3 A and Fig. 3 B, for the FFS mode liquid crystal display board 10A of embodiment 1, its direction is positioned at the centre of pixel capacitors 21 Widths physically along the center line 31 of signal wire 17 directions of the pixel capacitors 21 of each pixel.Yet the display width L2 that can realize accurately controlling transmitted light is approximately the distance from the blind end that is arranged on slit 20A one side on the pixel capacitors 21 to the open end 20A ' of opposite side.Therefore, its direction is positioned at the center of display width L2 along the display centre line 32 of the viewing area of signal wire 17, and to position that the open end of slit 20A 20A ' lateral deviation is moved.Here, if the width of pixel capacitors 21 is L1, the center line 31 and the distance, delta L between the display centre line 32 of pixel capacitors are as follows:
ΔL＝(L1-L2)/2
How many values of this Δ L exists some differences according to manufacturing facility as said at the narration of Figure 13 B, be approximately about 1～5 micron.
Therefore, among the FFS mode liquid crystal display board 10A of embodiment 1, its direction along with the center line 30 of colour filter 25AR, the 25AG of the direction of each pixel signal lines 17,25AB from the plane, be configured in display centre line 32 consistent location on.If so dispose colour filter, though becoming, moves colour filter to the open end of a slit 20A 20A ' lateral deviation, if be Rm but from the chromatic filter left end to the distance the viewing area, from the chromatic filter right-hand member is the words of Lm to the distance the viewing area, can make Rm=Lm, so can make the right side deviation tolerance level of colour filter equate with left side deviation tolerance level essence.Thus, even when assembling color filter substrate and array base palte, produce in certain deviation, also can realize the display width L2 of each pixel is in fact all covered from the plane, so allow the correct transmission of transmitted light in each pixel through predetermined colour filter 25AR, 25AG, 25AB, reduced generation thus by the mixed color phenomenon that light leak caused in the adjacent image point.
In addition, because the generation of mixed color phenomenon has reduced, though even such as still will form black matrix between adjacent colour filter, at least also may command is deceived the width of matrix, but also the structure of black matrix can be set shown in Fig. 3 B of embodiment 1 like that.In the FFS of embodiment 1 pattern, because the electric leakage field that produces between signal wire 17 and public electrode 14 is consistent with frictional direction, so near the liquid crystal molecule of the initial orientation signal wire 17 is subjected to this leakage electric field effects very little, because the rare confusion of initial orientation state of liquid crystal is so need not to be provided with especially black matrix.
