300 both sides laying respectively at protective layer 200, and black matrix removes district 100 and is positioned at light shield layer 300 in the projection of underlay substrate 31 and exists
In the projection of underlay substrate 31.
Herein it should be noted that the black matrix 32 that above-mentioned black matrix is removed in district 100 needs to be removed completely, so that
Electrostatic charge cannot pass through this black matrix and removes district 100, thus plays and prevent electrostatic from entering along black matrix 32 and be distributed and color film base
Purpose in plate 30.
Above-mentioned color membrane substrates is by the black matrix defined display area territory between all color-filter units and color-filter unit, and bag
Enclose this viewing area non-display area composition, wherein by black matrix be positioned at non-display area arrange encirclement viewing area black
Matrix removes district, owing to electrostatic cannot remove district through this black matrix such that it is able to prevents electrostatic from entering and is distributed in color film base
The viewing area of plate.On this basis, by non-display area, remove district in corresponding black matrix and deviate from the side of protective layer
Light shield layer is set, owing to light shield layer has, to light, the effect of blocking, so, incident ray under the blocking of light shield layer, nothing
Method removes the position in district through color membrane substrates correspondence black matrix, and then can enter along black matrix preventing electrostatic and be distributed in coloured silk
While in film substrate, it is to avoid the generation of light leakage phenomena.
Herein also, it should be noted the both sides that above-mentioned black matrix 32 and light shield layer 300 lay respectively at protective layer 200 are
Refer to, for example, it is possible to as it is shown on figure 3, light shield layer 300 is positioned at the protective layer 200 side near underlay substrate 31, black matrix 32 is positioned at
The side of protective layer 200 away from substrate substrate 31, in the case, when light is incident to this color membrane substrates 30 along O-O ' direction
Time, even if light can remove district 100 through black matrix, the shading of corresponding position, district 100 also cannot be removed through black matrix
Layer 300, so that light cannot remove the position in district 100 through the corresponding black matrix of color membrane substrates 30.
Again for example, it is also possible to as shown in Figure 2 a, light shield layer 300 is positioned at the side of protective layer 200 away from substrate substrate 31, black
Matrix 32 is positioned at the protective layer 200 side near underlay substrate 31, in the case, when light is incident to this coloured silk along O-O ' direction
During film substrate 30, under the effect of blocking of light shield layer 300, incident ray cannot remove district 100, i.e. light through black matrix cannot
The position in district 100 is removed through the corresponding black matrix of color membrane substrates 30.Hereinafter it is all that black matrix 32 is positioned at protective layer with in Fig. 2 a
200 near the side of underlay substrate 31, as a example by light shield layer 300 is positioned at the side of protective layer 200 away from substrate substrate 31, to this reality
It is further explained explanation with novel.
On this basis, above-mentioned light shield layer 300 is mainly used for shading, and this utility model is to constituting this light shield layer 300
Material does not limits, and can be black matrix material, it is also possible to for other lighttight materials.But in order to the most effective anti-
Only electrostatic charge enters in color membrane substrates 30 by light shield layer 300, and the resistivity of this utility model preferably this light shield layer 300 is more than
The resistivity of black matrix 32.
It addition, the material of the protective layer 200 constituted in color membrane substrates 30 can be inorganic material can also be organic material.
, protective layer 200 uses the inorganic material that dielectric constant is bigger to constitute in this utility model preferably, such as silicon nitride, silicon oxide,
Silicon oxynitride etc..Owing to the dielectric constant of this protective layer 200 is relatively big, even if therefore assembling certain electrostatic in black matrix 32
Lotus, under the effect of the protective layer 200 of this high-k, it is possible to reduce the electric field that this electrostatic charge produces, so, when this
When color membrane substrates 30 is applied to show in product, it is possible to reduce display picture and abnormal probability occurs.Additionally, this utility model
In, the side of protective layer 200 away from substrate substrate 31 can be formation state, and now this protective layer 200 can be as flatness layer.
On this basis, the protective layer 200 in this utility model can be with underlay substrate 31 edging, it is also possible to not edging,
This is not limited by this utility model.It addition, this utility model is preferred, as shown in Figure 2 a, protective layer 200 is used to be coated with black square
The form of battle array 32 so that black matrix 32 is isolated from the outside completely by protective layer 200, due to the insulating properties of protective layer 200, thus

Hereinafter above-mentioned black matrix is removed district 100 and be positioned at light shield layer 300 at underlay substrate 31 in the projection of underlay substrate 31
Projection in, be further explained explanation.
For example, it is possible to as shown in Figure 2 a, black matrix removes the district 100 projection at underlay substrate 31 with light shield layer 300 at lining
The projection of substrate 31 is completely superposed, and is S.
Again for example, it is possible to as shown in fig. 4 a, black matrix is removed district 100 and is existed with light shield layer 300 at the projection S of underlay substrate 31
The projection S ' of underlay substrate 31 not exclusively overlaps, and light shield layer 300 at least strides across black matrix and removes inner edge boundary line L in district 100 with black
Matrix 32 is positioned at the part of non-display area B and has overlapping region D.
It should be noted that for collimated incident light, in above-mentioned Fig. 2 a and Fig. 4 a, black matrix is removed district 100 and is hidden
The set-up mode of photosphere 300 all can well play shaded effect, it is possible to enters preventing electrostatic along black matrix 32 and is distributed in
While in color membrane substrates 30, it is to avoid the generation of light leakage phenomena.
And for non-aligned incident ray, as shown in Figure 2 a, owing to protective layer 200 self has certain thickness,
So that side entering type light E can be incident to black matrix by protective layer 100 removes district 100, and then the risk of light leak occurs.
Therefore, for non-aligned incident ray, this utility model preferably uses black matrix in Fig. 4 a to remove district 100 and light shield layer 300
Set-up mode, there is overlapping region D, to avoid by the part that light shield layer 300 and black matrix 32 are positioned at non-display area B
Side entering type light E is incident to black matrix through protective layer 100 and removes district 100, and then can effectively prevent light leakage phenomena from occurring.
On this basis, the width of above-mentioned overlapping region D increases along with the increase of protective layer 100 thickness.Concrete, as
Shown in Fig. 4 b (Fig. 4 a partial enlarged drawing at the P of position), at side entering type light E in the case of inclined angle alpha is certain, work as protection
When layer 100 thickness are H1, the width of overlapping region is D1；When protective layer 100 thickness increases to H2 from H1, the width of overlapping region
Degree increases to D2 from D1.Such as, when protective layer 100 thickness is reduced to 1 μm, the width of overlapping region is reduced to 20 μm；Work as guarantor
When sheath 100 thickness is 2 μm, the width of overlapping region is 50 μm.

Substrate 31 edge is as annular region Q in boundary line, outside, as shown in Fig. 4 a (side schematic view of Fig. 6), owing to black matrix is removed
District 100 is set directly at the outward flange of underlay substrate 31, so that the electrostatic charge in the external world cannot remove district by this black matrix
100 enter color membrane substrates 30.
On this basis, removing district 100 when above-mentioned black matrix is, using underlay substrate 31 edge as the annular in boundary line, outside
When the width of region Q is less than 200 μm, the irregularly shaped object in the external world, such as finger etc. may be caused, district can be removed through black matrix
100 contact with black matrix 32, thus can not effectively prevent electrostatic charge from entering in color membrane substrates 30, and therefore, this utility model is excellent
Choosing, the width of this annular region is more than or equal to 200 μm, effectively to prevent extraneous static lotus from entering color membrane substrates 31.
It addition, on the premise of the width of above-mentioned notching construction and the width of annular region Q are suitable, as shown in Figure 5 a,
