In one embodiment of this invention, above-mentioned rigid substrates is transparent glass substrate.
In one embodiment of this invention, above-mentioned rigid substrates is quartz glass substrate.
In one embodiment of this invention, the material of above-mentioned release layer is styrene (styrene), maleic anhydride multipolymer (maleic anhydride copolymer) or silicones (silicone).
In one embodiment of this invention, above-mentioned flexible base plate layer is slim glass substrate layer or plastic base flaggy.
In one embodiment of this invention, the material of above-mentioned flexible base plate layer is polyethylene terephthalate (Polyethylene Terephthalate, PET), Polyethylene Naphthalate (Polyethylene Naphthalate, PEN), aromatic polyamide (Polyaramid), polyimide, poly-cycloolefin (Polycycloolefin), polysulfones (Polysulfone), epoxy resin (Epoxy), polycarbonate (Polycarbonate, PC) or polymethyl acrylate (Polymethacrylate, PMA).
As from the foregoing, in the manufacture method of flexible color filter substrate of the present invention, owing to being provided with release layer between rigid substrates and flexible base plate layer, so do not need to peel off processing procedure by laser, separate rigid substrates and flexible base plate layer.So, can prevent that flexible base plate layer from the situation of yellow occurring because of laser light illumination, and then promote the optical property of flexible color filter substrate.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, and for above and other objects of the present invention, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.

Embodiment
Technological means and the effect for further setting forth the present invention, for reaching predetermined goal of the invention, taked, below in conjunction with accompanying drawing and preferred embodiment, to its embodiment of manufacture method, method, step, structure, feature and the effect of the flexible color filter substrate proposing according to the present invention, be described in detail as follows.
Relevant aforementioned and other technology contents of the present invention, Characteristic, can clearly present in following cooperation in describing in detail with reference to graphic preferred embodiment.By the explanation of embodiment, can have one more deeply and concrete understanding for technological means and the effect reaching predetermined object and take to the present invention, but appended graphic be only to provide with reference to the use of explanation, be not used for the present invention to be limited.
Figure 1A to Fig. 1 F is the schematic flow sheet of the manufacture method of the flexible color filter substrate of one embodiment of the invention.Please refer to Figure 1A, the manufacture method of the flexible color filter substrate of the present embodiment is that first rigid substrates 12 is provided.Rigid substrates 12 can be transparent glass substrate, as quartz glass substrate.Rigid substrates 12 has relative upper surface 122 and lower surface 124.Upper surface 122 comprises first area 1222 and second area 1224, and second area 1224 is positioned at the periphery of first area 1222.
Then, please refer to Figure 1B, on the first area 1222 of upper surface 122, form release layer 14.The material of release layer 14 can be styrene, maleic anhydride multipolymer or silicones, but not as limit.
Please refer to Fig. 1 C, form after release layer 14, is then to form flexible base plate layer 16.Flexible base plate layer 16 covers second area 1224 and release layer 14.Flexible base plate layer 16 can be slim glass substrate layer or plastic base flaggy, but not as limit.Particularly, when the material of flexible base plate layer 16 is plastics, it can be polyethylene terephthalate, Polyethylene Naphthalate, aromatic polyamide, polyimide, poly-cycloolefin, polysulfones, epoxy resin, polycarbonate or polymethyl acrylate.
Please refer to Fig. 1 D, form after flexible base plate layer 16, then form colorama resistance layer 18.The colorama resistance layer 18 forming is positioned on the part flexible base plate layer 16 of release layer 14 tops.In other words, colorama resistance layer 18 is formed at 1222 tops, first area.In addition, colorama resistance layer 18 for example comprise be array arrange multiple chromatic photoresists and in order to separate the black matrix" (blackmatrix) of these chromatic photoresists.
Please refer to Fig. 1 E, form after colorama resistance layer 18, intersection cutting rigid substrates 12 and flexible base plate layer 16 along first area 1222 with second area 1224.The method of cutting rigid substrates 12 and flexible base plate layer 16 can be laser cutting, but not as limit.Specifically, the method for cutting rigid substrates 12 and flexible base plate layer 16 can adopt laser beam 19 to cut the intersection of first area 1222 and second area 1224, thereby partially rigid substrate 121 and part flexible base plate layer 161 are removed.That is, rigid substrates 12 is cut into the rigid substrates 121 that comprises second area 1224 and the rigid substrates 123 that comprises first area 1222, and flexible base plate layer 16 is cut into the flexible base plate layer 161 and the flexible base plate layer 162 that is positioned at 1222 tops, first area that are positioned at second area 1224 tops.
Please refer to Fig. 1 F, after cutting rigid substrates 12 and flexible base plate layer 16, then separate release layer 14 and flexible base plate layer 162, flexible base plate layer 162 and colorama resistance layer 18 formed thereon are isolated from rigid substrates 12, thereby form flexible color filter substrate 10.
In the present embodiment, due to release layer 14 is formed between rigid substrates 12 and flexible base plate layer 162, so can easily flexible base plate layer 162 be isolated from rigid substrates 12 by release layer 14.So, can omit laser of the prior art and peel off processing procedure, thereby avoid flexible base plate layer 162 to produce the situation of yellow because of laser light illumination.Therefore, the manufacture method of the flexible color filter substrate of the present embodiment can promote optical property and the optical stabilization degree of flexible color filter substrate.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, although the present invention discloses as above with preferred embodiment, but not in order to limit the present invention, any those skilled in the art, do not departing within the scope of technical solution of the present invention, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solution of the present invention content, any simple modification of above embodiment being done according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
