[specific embodiment]
The explanation of following embodiment is to can be used to the particular implementation of implementation to illustrate the present invention with reference to additional schema
Example.The direction term that the present invention is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outside", " side "
Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the present invention, rather than to
The limitation present invention.The similar unit of structure is to be given the same reference numerals in the figure.
With reference to Fig. 2-6, Fig. 2-6 is the schematic diagram of each step of color membrane substrates production method of the invention.
The production methods of color membrane substrates of the invention the following steps are included:
S201, color blocking layer is formed on underlay substrate, the color blocking layer includes multiple color films, phase between two neighboring coloured silk film
It is mutually overlapping;
For example, as shown in Fig. 2, the photoresist of three kinds of colors is respectively coated on underlay substrate 11, using mask plate to upper
It states photoresist to be exposed, is developed again later, etched, being formed has red color film 101, green tint film 102, blue color film
103 color blocking layer, it is mutually overlapping between two neighboring coloured silk film.
S202, the light initiator that short wavelength is mixed in the flat layer material with birefringence, obtain mixing material;It will
The mixing material is coated in the color blocking layer;;
As shown in figure 3, mixing the light initiator of short wavelength in the flat layer material with birefringence, this is mixed later
Condensation material 21 is coated in color blocking layer.
S203, the mixing material of lightproof area is exposed, to form light shielding part in the lightproof area;
As illustrated in figures 4-5, wherein the position phase in the lightproof area region mutually overlapping with the two neighboring color film
It is corresponding;Lightproof area position as shown in the dotted line frame in Fig. 4, is exposed the mixing material of lightproof area;
Since the light initiator of short wavelength being added in flat layer material, when irradiating lightproof area with the light of short wavelength, light
Initiator causes flat layer material and photochemical reaction occurs, to change the birefringence of the flatness layer.When illumination is mapped to the material
When expecting surface, the region through overexposure is since the refractiveness of light changes, prevent light is from penetrating, namely rises and forms shading
Portion 211.Without the region through overexposure, since refractive index characteristic does not change, so that light passes through.
S204, the mixing material after exposure is carried out to be formed by curing flatness layer.
As shown in fig. 6, solidifying to the mixing material after exposure, flatness layer 22 is formed.
Preferably, the thickness difference between the flatness layer 22 and the color blocking layer is less than or equal to 0.25 micron.Due to thickness
It is too big, increase the thickness of color membrane substrates, and thickness is too small, is unfavorable for the surfacing of color membrane substrates.
Preferably, the flat layer material with birefringence is organic transparent material.Since organic transparent material has
Have a preferable birefringence characteristic, thus by exposure after, be capable of forming the higher light shielding part of shading factor.
Preferably, above-mentioned production method can also include:
S205, introns are formed on position corresponding with the light shielding part.
As shown in fig. 7, form introns on the light shielding part 211, the introns may include main spacer 23 and time
Introns 24.Due to forming the introns on light shielding part, the light transmittance of entire panel will not influence.
Preferably, the material of the introns is organic transparent material.Namely the material of the introns 23 and 24 is to have
Machine transparent material, to further increase the light transmittance of liquid crystal display panel.
Color membrane substrates of the invention and preparation method thereof, it is flat due to using the flat layer material with birefringence to make
Layer carries out shading by the light shielding part, since the flat layer material with birefringence has so that flatness layer forms light shielding part
Higher impedance, therefore electric conductivity is poor, so that light shielding part is non-conductive, to effectively prevent static release circuit leakage
Electricity reduces production cost.Simultaneously because not needing one layer of black matrix" of independent processing procedure, production process is simplified, is further dropped
Low production cost.
The present invention also provides a kind of color membrane substrates, as shown in Figure 7 comprising underlay substrate 11, color blocking layer, flatness layer 22;
The material of the underlay substrate 11 can be transparent glass;
The color blocking layer is located on the underlay substrate 11;The color blocking layer includes multiple color films;Between two neighboring coloured silk film
It is mutually overlapping;Such as color blocking layer includes red color film 101, green tint film 102 and blue color film 103;
The flatness layer 22 is located in the color blocking layer, and the flatness layer 22 includes multiple light shielding parts 211;The wherein shading
Portion 211 is corresponding with the mutually overlapping position in region of the two neighboring color film, and the material of the flatness layer includes with double
The flat layer material of refractive index and the light initiator of short wavelength.
Preferably, the thickness difference between the flatness layer 22 and the color blocking layer is less than or equal to 0.25 micron.Due to thickness
It is too big, increase the thickness of color membrane substrates, and thickness is too small, is unfavorable for the surfacing of color membrane substrates.
Preferably, the flat layer material with birefringence is organic transparent material.Since organic transparent material has
Have a preferable birefringence characteristic, thus by exposure after, be capable of forming the higher light shielding part of shading factor.
Preferably, introns are formed on position corresponding with the light shielding part.As shown in fig. 7, in the light shielding part 211
Upper formation introns, the introns may include main spacer 23 and minor tick 24.Due to forming the introns in light shielding part,
It will not influence the light transmittance of entire panel.
Preferably, the material of the introns is organic transparent material.Namely the material of the introns 23 and 24 is to have
Machine transparent material, to further increase the light transmittance of liquid crystal display panel.
Color membrane substrates of the invention, due to using the flat layer material with birefringence to make flatness layer, so that flat
Layer forms light shielding part, carries out shading by the light shielding part, due to the flat layer material impedance with higher with birefringence,
Therefore electric conductivity is poor, so that light shielding part is non-conductive, to effectively prevent static release circuit electric leakage, reduces production
Cost.Simultaneously because not needing one layer of black matrix" of independent processing procedure, production process is simplified, further reduced production cost.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit
The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention
Decorations, therefore protection scope of the present invention subjects to the scope of the claims.
