[detailed description of the invention]
The explanation of following embodiment is graphic with reference to add, can in order to illustrate the present invention
In order to the specific embodiment implemented.The direction term that the present invention is previously mentioned, such as " on ",
D score, "front", "rear", "left", "right", " interior ", " outward ", " side " etc., only
It it is the direction with reference to annexed drawings.Therefore, the direction term of use is to illustrate and manage
Solve the present invention, and be not used to limit the present invention.In the drawings, the unit that structure is similar be with
Identical label represents.
With reference to Fig. 2-6, Fig. 2-6 is each step of color membrane substrates manufacture method of the present invention
Schematic diagram.
The manufacture method of the color membrane substrates of the present invention comprises the following steps:
S201, forming color blocking layer on underlay substrate, described color blocking layer includes multiple color film,
Between adjacent two color films the most overlapping；
Such as, as in figure 2 it is shown, be respectively coated three kinds of colors on underlay substrate 11
Photoresist, use mask plate that above-mentioned photoresist is exposed, carry out the most again developing,
Etching, is formed and has red color film 101, green tint film 102, blue color film 103
Color blocking layer, the most overlapping between adjacent two color films.
S202, mix in the flatness layer material have birefringence short wavelength light initiate
Agent, obtains mixing material；Described mixing material is coated on described color blocking layer；；
As it is shown on figure 3, mix short wavelength's in the flatness layer material have birefringence
Light initiator, is coated on this mixing material 21 on color blocking layer afterwards.
S203, mixing material to lightproof area are exposed, with at described lightproof area
Form light shielding part；
As illustrated in figures 4-5, wherein said lightproof area is mutual with described adjacent two color films
The position in overlapping region is corresponding；This lightproof area is as shown in the dotted line frame in Fig. 4
Position, is exposed the mixing material of lightproof area；
Owing to flatness layer material adding the light initiator of short wavelength, when with the light of short wavelength
When irradiating lightproof area, light initiator causes flatness layer material generation photochemical reaction, from
And change the birefringence of this flatness layer.When light is irradiated to this material surface, through overexposure
The region of light changes due to the refrangibility of light so that light can not pass through, Ye Jiqi
Form light shielding part 211.And not through the region of overexposure, owing to refractive index characteristic is not sent out
Changing so that light passes through.
S204, to exposure after mixing material solidify to form flatness layer.
As shown in Figure 6, the mixing material after exposure is solidified, form flatness layer
22。
Preferably, the thickness difference between described flatness layer 22 and described color blocking layer is less than
In 0.25 micron.Owing to thickness is too big, increases the thickness of color membrane substrates, and thickness is too
Little, it is unfavorable for the surfacing of color membrane substrates.
Preferably, the flatness layer material described in birefringence is organic transparent material.
Owing to organic transparent material has a preferable birefringence characteristic, therefore by exposure after,
The light shielding part that shading factor is higher can be formed.
Preferably, above-mentioned manufacture method can also include:
S205, on the position corresponding with described light shielding part formed introns.
As it is shown in fig. 7, form introns on described light shielding part 211, these introns can
To include master space 23 and minor tick 24.Owing to forming this interval on light shielding part
Son, does not interferes with the light transmittance of whole panel.
Preferably, the material of described introns is organic transparent material.Namely described interval
The material of son 23 and 24 is organic transparent material, thus increases LCD further
The light transmittance of plate.
Color membrane substrates of the present invention and preparation method thereof, has birefringence owing to using
Flatness layer material makes flatness layer so that flatness layer forms light shielding part, by this light shielding part
Carry out shading, owing to having the flatness layer material of birefringence, there is higher impedance, because of
This electric conductivity is poor so that light shielding part is non-conductive, thus effectively prevent electrostatic and release
The electric leakage of electric discharge road, reduces production cost.Simultaneously because it is black to need not independent processing procedure one layer
Colour moment battle array, simplifies production process, reduce further production cost.
The present invention also provides for a kind of color membrane substrates, as it is shown in fig. 7, it includes underlay substrate
11, color blocking layer, flatness layer 22；The material of this underlay substrate 11 can be clear glass；
This color blocking layer is positioned on described underlay substrate 11；Described color blocking layer includes multiple coloured silk
Film；Between adjacent two color films the most overlapping；Such as color blocking layer include red color film 101,
Green tint film 102 and blue color film 103；
This flatness layer 22 is positioned on described color blocking layer, and described flatness layer 22 includes multiple screening
Light portion 211；Wherein said light shielding part 211 mutually overlaps with described adjacent two color films
The position in region is corresponding, and the material of described flatness layer includes having the smooth of birefringence
The light initiator of layer material and short wavelength.
Preferably, the thickness difference between described flatness layer 22 and described color blocking layer is less than
In 0.25 micron.Owing to thickness is too big, increases the thickness of color membrane substrates, and thickness is too
Little, it is unfavorable for the surfacing of color membrane substrates.
Preferably, the flatness layer material described in birefringence is organic transparent material.
Owing to organic transparent material has a preferable birefringence characteristic, therefore by exposure after,
The light shielding part that shading factor is higher can be formed.
Preferably, the position corresponding with described light shielding part forms introns.Such as Fig. 7
Shown in, described light shielding part 211 is formed introns, these introns can include between master
Every son 23 and minor tick 24.Owing to forming this introns at light shielding part, do not interfere with
The light transmittance of whole panel.
Preferably, the material of described introns is organic transparent material.Namely described interval
The material of son 23 and 24 is organic transparent material, thus increases LCD further
The light transmittance of plate.
The color membrane substrates of the present invention, owing to using the flatness layer material system with birefringence
Make flatness layer so that flatness layer forms light shielding part, carries out shading by this light shielding part, by
Having higher impedance in the flatness layer material with birefringence, therefore electric conductivity is relatively
Difference so that light shielding part is non-conductive, thus effectively prevent static release circuit electric leakage,
Reduce production cost.Simultaneously because need not one layer of black matrix" of independent processing procedure, simplify
Production process, reduce further production cost.
In sum, although the present invention is disclosed above with preferred embodiment, but above-mentioned excellent
Select embodiment and be not used to limit the present invention, those of ordinary skill in the art, not taking off
In the spirit and scope of the present invention, all can make various change and retouching, the therefore present invention
Protection domain define in the range of standard with claim.
