Detailed description of the invention
Understandable for enabling the above-mentioned purpose of the present invention, feature and advantage to become apparent from, the most right
The detailed description of the invention of the present invention is described in detail.
Elaborate a lot of detail in the following description so that fully understanding the present invention, but the present invention is also
Other can be used to be different from alternate manner described here implement, therefore the present invention is not by following public tool
The restriction of body embodiment.
Secondly, the present invention combines schematic diagram and is described in detail, when describing the embodiment of the present invention in detail, for ease of saying
Bright, represent that the profile of apparatus structure can be disobeyed general ratio and be made partial enlargement, and described schematic diagram simply shows
Example, it should not limit the scope of protection of the invention at this.Additionally, length, width should be comprised in actual fabrication
And the three-dimensional space of the degree of depth.
For the feature of the prominent present invention, accompanying drawing does not provide the portion the most relevant to the inventive point of the present invention
Point, such as, the thin film transistor (TFT) being connected with pixel electrode.
At present, in the display panels of various display patterns, such as PVA pattern or the liquid crystal of MVA pattern
Show panel, general by etching formation projection or crack in pixel cell so that liquid crystal molecule is formed certain
Pre-dumping, in order to can control liquid crystal molecule in the power-on state and be rapidly converting to, improves response speed.
But, form the protruding or process in crack, add processing step, and to the precision of manufacture process and
Prescription is higher, will affect product yield accordingly, improves manufacturing cost.
Based on this, the present invention provides a kind of display panels and manufacture method thereof, it is not necessary to form projection
Or etching fracture, it is not required that change other structures of pixel cell, it is possible to realize the pre-of liquid crystal molecule
Inclining, concrete, side's insulating barrier arranges narrow slit structure on the pixel electrode, utilizes half gray-level mask technology by biphase
On adjacent sub-pixel, insulating barrier produces different-thickness, i.e. obtains different capacitive dielectric layers, former according to capacitance partial pressure
Reason, the voltage difference at the one the second sub-pixel liquid crystal capacitance two ends can be variant, thus affects lqiuid crystal molecule tipping journey
Degree, it is achieved the multidomain of display panels shows.Additionally, in color film side, be correspondingly arranged shading matrix to liquid crystal
Molecule topples over the same structure playing orientation, and this structure makes liquid crystal molecule topple over toward same direction, thus accelerates
The liquid crystal response time, and eliminate black streak phenomenon, improve penetrance.Use the present invention that color film side can be made without increasing
Projection or slit process, realize multidomain without light alignment technique, and processing procedure is simple such as TN.
Describe described display panels and manufacture method embodiment thereof below in conjunction with the accompanying drawings in detail.
Fig. 1 is the pixel cross-sectional structure of the vertically displayed mode LCD of one embodiment of the invention multidomain
Schematic diagram.
With reference to Fig. 1, the vertically displayed mode LCD of multidomain of the present invention include a upper substrate 120,
One infrabasal plate 110 and be filled in the liquid crystal layer 130 between upper and lower base plate 110 and 120；Described infrabasal plate 110
Viewing area include multiple subpixel area, be provided with in sub-pixel pixel electrode 113 and TFT device (figure
Not shown in), above pixel electrode 113, the second insulating barrier 114 is formed with slit 115, ties from this slit 115
LC molecule is toppled over and is played orientation by the electric field of structure ejection；Described upper substrate 120 surface is formed public
Electrode 121, public electrode 121 is formed black matrix (BM) 122, and wherein, the material of BM122 can
Think that black resin or crome metal are made.The slit formed on described pixel electrode 113, with BM122 just
Right.This structure makes LC molecule topple over toward same direction, thus accelerates the LC response time, and it is existing to eliminate black stricture of vagina
As, improve penetrance.Due to BM bulge-structure, belong to the black matrix covering array side metal light leak with along with
Light shield defines, and therefore without as MVA, increases the film forming exposure imaging technique of protruding (bump) structure.
Wherein, pixel electrode 113, public electrode 121 material may be selected to be indium tin oxide or indium-zinc oxide.
It addition, as it is shown in figure 1, the lap of d1 i.e. pixel electrode 113 and common wire 111 is 2～4um to be
Excellent, to take into account the electric field force intensity between common wire and pixel electrode, and pixel aperture ratio requirement.
With reference to Fig. 2, the liquid crystal analog result of its corresponding diagram 1, liquid crystal molecule all topples over along prescribed direction perfection,
Penetrance curve is the most saturated.
Fig. 3 is the pixel principle figure of example 1, if figure be laterally scan line 116, row to for data wire 117,
Between public electrode 121 on pixel electrode 113 and upper substrate 120, there is the electric capacity Cx that insulating barrier is formed
And liquid crystal capacitance Clc, both become cascaded structure.Additionally pixel electrode 113 and array base palte 110 common wire 111
Between, there is storage electric capacity Cst.
Fig. 4 is the pixel cross section knot of the vertically displayed mode LCD of another embodiment of the present invention multidomain
Structure schematic diagram.
Fig. 4 is the pixel cross-sectional view of this motion example 2.Example 2 is than the difference of example 1, real
In example 2, pixel electrode 213 and common wire 211 are positioned at same level, make common wire 211 and pixel electrode
Electric field between 213 is higher evenly.On the other hand, have above pixel electrode 213 first insulating barrier 212 with
Second insulating barrier 214, it is assumed that both thickness are respectively 4000A, then pixel electrode 213 overlying insulating layer thickness is then
For 8000A；And only having the second insulating barrier 114, i.e. slit depth above example 1 pixel electrode is 4000A.
Slit depth is the biggest, and the liquid crystal response time is the fastest.So example 2 is than example 1, advantage shows as liquid crystal and rings
Between Ying Shi faster.Reason has two: (1) pixel electrode 213 and common wire 211 are positioned at same level；(2) narrow
Stitch 215 degree of depth bigger.Additionally in Fig. 4, d2 i.e. pixel electrode 213 with common wire 211 distance with 2～4um is
Excellent.
Fig. 5 is the pixel cross section of the vertically displayed mode LCD of multidomain of further embodiment of this invention
Structural representation.(saving common wire to arrange, the pixel planes figure of Fig. 7 example 3 is asked for an interview in detailed design) herein.
