The mixture of agent.
The thickness of the barrier film layer can be more than or equal to required molten when needing to manufacture the chromatic filter layer of preset thickness
The height of liquid.In practical application, the thickness for the chromatic filter layer that needs manufacture can be determined according to the actual demand of product, then
Determined to need to be sprayed into the height of the solution in pixel region according to the thickness of the chromatic filter layer, further according to the solution of the determination
Height determine the thickness of barrier film layer.Illustratively, it is assumed that the thickness for the colored filter for needing to manufacture is n microns, manufactures the n
The height of solution needed for the thick colored filter of micron is 4n microns, then in order to prevent the molten of the chromatic filter layer of different colours
Liquid crossfire between pixel region, the thickness of the barrier film layer should be greater than or equal to 4n micron, normally, the thickness of the barrier film layer
Degree can be (1.0~1.3) * 4n microns.Such as：The thickness of certain colored filter for needing to manufacture is 2 microns, and it is 2 micro- to manufacture this
The height of solution needed for the thick colored filter of rice is 8 microns, then the thickness of the barrier film layer can be 8.5 microns.
Illustratively, Fig. 3-4 are refer to, it illustrates provided in an embodiment of the present invention a kind of formed with black matrix 002
The structural representation formed on underlay substrate 001 after barrier film layer P.
Alternatively, the chromatic filter layer formed on color membrane substrates can include multiple colored filters, also, according to colour
The different set-up modes of optical filter, above-mentioned barrier film layer can be arranged on underlay substrate according to following two modes：
In the first set-up mode, multiple orthographic projections of the shielding barricades on underlay substrate 001 refer to Fig. 3-5 (for
It is easy to watch, black matrix not shown in Fig. 3-5), orthographic projection of multiple shielding barricades on underlay substrate 001 is multiple along first
Gap area Q1 coverings between the strip projection 0031b of direction A1 arrangements, each two strip projection 0031b are multiple along second party
The pixel region S to be arranged to A2, and a colored filter can be provided with each gap area Q1, it that is to say, between each
The colored filter set in multiple pixel region S of gap region Q1 coverings is structure as a whole, and first direction A1 and second party
Intersect to A2, as in Figure 3-5, first direction A1 is vertical with second direction A2.Alternatively, in each gap area Q1
The colored filter of setting can be any in red color filter piece, green colored filter and blue color filter
Kind.
When target shielding barricade 0031 is set according to the first set-up mode, due to each gap area Q1 coverings
The colored filter set in multiple pixel region S is structure as a whole, and target need not be set to shield between the plurality of pixel region S
Barricade 0031 so that surface of the colored filter away from underlay substrate 001 set in the plurality of pixel region S is a plane
(that is to say that the colored filter formed on each gap area Q1 is flood structure), the plane can further improve color film
The flatness of substrate surface, also, the manufacturing process of chromatic filter layer 004 can also be simplified.
In second of set-up mode, multiple orthographic projections of the shielding barricades on underlay substrate 001 refer to Fig. 3-6 (for

It is alternatively possible to spraying is dissolved with manufacture colorized optical filtering in the region limited using ink-jetting process to shielding barricade
The solution of the material of layer, to obtain colorized optical filtering solution.Wherein, in colorized optical filtering solution the solution of different colours by multiple shieldings
Barricade barrier.
Illustratively, Fig. 3-7 are refer to, a kind of are limited it illustrates provided in an embodiment of the present invention in barrier film layer P
The structural representation formed in region after colorized optical filtering solution C.
Step 305, baking processing is carried out to barrier film layer and colorized optical filtering solution, be sequentially overlapped screen layer,
Chromatic filter layer and melting layer.
In practical application, baking processing is carried out to barrier film layer and colorized optical filtering solution, with the shielding being sequentially overlapped
Layer, chromatic filter layer and melting layer, can at least there is following two achievable modes：
The first can realize mode, first baking processing be carried out to colorized optical filtering solution using the first temperature, to obtain colour
Filter layer, then, baking processing is carried out to barrier film layer using second temperature, to obtain screen layer and melting layer.Wherein, first
Temperature is less than the fusing point of heat-fusible materials, and second temperature is higher than the fusing point of heat-fusible materials, illustratively, it is assumed that heat-fusible materials

Multiple fusing departments that solid after Gu is as formed on surface of the chromatic filter layer away from underlay substrate, and the plurality of fusing department
The state for flowing to surface of the chromatic filter layer away from underlay substrate is still remain, its height is less than shielding gear corresponding to the fusing department
Height before wall fusing, that is to say, when the height of fusing department is less than the chromatic filter layer that same thickness is manufactured in correlation technique
The thickness of required barrier film layer (i.e. black matrix), that is, efficiently reduce the segment difference between barrier film layer and chromatic filter layer.
After overbaking is handled, the part that barrier film layer contacts with chromatic filter layer does not deform upon, and the part is formed as
Screen layer, the screen layer include multiple targets shielding barricade, and orthographic projection and step of the target shielding barricade on underlay substrate
The shape of orthographic projection of the multiple shielding barricades formed in rapid 303 on underlay substrate is identical.
Illustratively, the barrier film layer P shown in Fig. 3-8 is carried out using second temperature the screen layer that is obtained after baking processing and
