Embodiment
The wire grid polarizer of the utility model is to include base material, be formed on the resin coating on the said base material and be formed on the wire grid polarizer of the metal wire on the said resin coating, is the wire grid polarizer that can be under the state of the structure of keeping said metal wire separates said base material from this wire grid polarizer.Such method of application below such wire grid polarizer for example can adopt, that is, the wire grid polarization film that only will comprise metal wire and resin coating spreads on the article of the glass of liquid crystal display cells etc., and base material separates and removes from wire grid polarization film.
As the base material that constitutes wire grid polarizer, be preferably temporarily to carry and hold resin coating, can be adjusted into the base material below the 5N/25mm separating the wire grid polarization film and the operation resin coating of base material and the peeling force of base material.
The form of base material does not have special qualification, the such shape of film or the sheet of the such shape of conveyer belt, roller shape, upright and outspoken and smooth thin slice (piece leaf) shape, softness is arranged for example and have the lamella shape etc. of bendability.The material of base material has the inorganic material of the such metal of iron, stainless steel, titanium or resin, glass, pottery etc. for example.In these materials, aspect intensity, permanance, the base material of metal belt shape is comparatively desirable, aspect the operational ease of the easness of the manufacturing of large-area wire grid polarizer, wire grid polarizer, then is that the plastic film substrate of film shape is more satisfactory.As plastic film substrate, be preferably transparent and the uniform material of thickness.
From price, consider with the fissility aspect of base material; Be preferably; For example polyethylene (PE) resin, acrylic resin (PP), cross-linked polyethylene resin, Corvic, cycloolefin (COP) resin, cyclic olefine copolymer (COC) resin, polystyrene (PST) resin, pet resin (PET), polybutylene terephthalate (PBT) resin (PBT), PEN (PEN) resin, polyarylate (PAR) resin, Merlon (PC) resin, polyamide (PA), polyimides (PI) resin, PEI (PEI) resin, polyphenylene oxide resin, modified polyphenylene ether resin, polyether sulfone (PES) resin, polysulfone resin, polyether ketone resin, acetal resin (POM), plexiglass, Triafol T (TAC) resin etc.; Consider that from processability, intensity, excellent heat resistance aspect PET, PC, COP, COC, TAC are more preferably.
Its material of the thickness of base material is all not special to be limited; Usually can use the base material of the scope of 4 μ m～2mm, but consider that from easy, the operating aspect made the scope of 8 μ m～500 μ m is more satisfactory; Consider that from continuous throughput rate aspect then the scope of 15 μ m～200 μ m is desirable especially.
Be selected from the manufacturing process of wire grid polarizer, keeping operation, transporting the sprawling in the more than one operation in the operation of operation, wire grid polarization film; Base material can temporarily carry holds resin coating; In the operation of separating wire grid polarization film and base material, need to keep the structure of metal wire.The structure of keeping metal wire is meant, before and after the operation of separating wire grid polarization film and base material, does not give the damage of degree that the performance of wire grid polarization film is impacted in the unexpected part of wire grid polarization film.Unexpected part is meant, for example the shear line when shearing wire grid polarization film according to purposes wittingly and it is made desirable shape and, the place near the zone that is not used in this purposes in the shear line and the outside.So-called damage is meant, for example diameter is crossed damaged, the pollution of the wire grid polarization film of 500 μ m size, the diagonal distortion of metal wire etc.
In order under the state of the structure of keeping metal wire like this, to separate polarizing coating and base material, the peeling force that is preferably resin coating and base material can be adjusted into the base material below the 5N/25mm.In order in the shorter time, to carry out the separation circuit of wire grid polarization film and base material more efficiently, be preferably peeling force and can be adjusted into the base material below the 3N/25mm.Method of adjustment as peeling force; Peeling force in the operation before the operation of separating wire grid polarization film and base material is under the situation below the peeling force in the operation of separating wire grid polarization film and base material; Hold resin coating though can temporarily stably carry, for this reason, the peeling force of wire grid polarization film and base material is more satisfactory more than the 0.1N/25mm; In order in the shorter time, to carry out the operation of front efficiently, the peeling force of wire grid polarization film and base material is desirable more more than the 0.5N/25mm.
Concrete grammar as such adjustment peeling force; Have for example: (first) to be soaked into the physical bond power that waits and adjusted in order to utilize for the method utilizing chemical bond power to adjust to import or remove functional group with the adhesion of the face of the resin coating of base material bonding, (second), and the reinforcement of the immersion conditions of the resin coating material of composition through being prone to bonding coating, corona treatment, surface roughening processing, resin coating material or temperature, time, pressure etc. waits the method for strengthening adhesion.Perhaps, through the coating of difficulty bonding, burin-in process, surface densification handle, the composition of resin coating material or temperature, constantly, the mitigation of the immersion conditions of the resin coating material of pressure etc. waits the method that reduces adhesion.(the third) method etc. that the means that can carry out outside adjustment are adjusted the peeling force of base material and resin coating such as controls through static, magnetic force, vacuum suction, machinery.
In these methods; Through the coating of difficulty bonding, burin-in process, surface densification handle, the composition of resin coating material or temperature, hour, the mitigation of the immersion conditions of the resin coating material of pressure etc. waits the method that reduces adhesion more satisfactory; Especially; To on base material film, become the time that makes after the light-cured resin of resin coating till its ultraviolet curing reaction behind the coating curing was made as in 2 seconds; Because it is can adjust amounts of saturation lower, so more satisfactory to the light-cured resin of base material film.Further, be made as 1 second with interior then desirable more.In addition, said here curing reaction is meant, after curing reaction, becomes the reaction that can be used as the state of resin coating, and Photocurable resin composition can 100% curing.Again, be made as-20 ℃～150 ℃, can bring into play adhesion as purpose through the delivery temperature that will make light-cured resin ultraviolet curing when reaction.Better is 0 ℃～60 ℃.
With respect to this method, patent documentation 3 disclosed contents do, base material and resin coating are firmly bondd, and the deterioration that is suppressed under hot and humid is one of purpose.Based on this thought, just do not have imagination that light-cured resin is not fully soaked at it and before base material, solidify such transport condition.
An aspect, technological thought and solution thereof that the peeling force with base material and resin coating of the utility model keeps lowlyer are to be conceived to base material is separated such problem with resin coating in the utility model, are therefore found first.
On the other hand; Under the situation of peeling force in the operation of separating wire grid polarization film and base material less than the peeling force in the operation before the operation of separating wire grid polarization film and base material; Concrete grammar as that kind adjustment peeling force; The method that peeling force in the operation of separating wire grid polarization film and base material is improved through following method is arranged for example; Promptly to the material at the interface of base material or resin coating or base material and resin coating, (fourth) adopts the resin of the such ease of solubility that is soluble in solvent of PST resin, through with the method that contacts the adjustment peeling force of solvent, the resin that (penta) adopts the such easy pyrolytic of POM resin; Method, (own) through heating adjustment peeling force adopt photosensitive material, adjust the method for peeling force etc. through exposure.Except that these, also have for example: the official post interface of (heptan) expansion coefficient through utilizing base material and resin coating produces the method for adjusting peeling force in the crack, (suffering) are controlled etc. the peeling force of means adjustment base material and resin coating that can outside adjustment through static, magnetic force, vacuum suction, machinery method etc.
The preferably processing of the peeling force of the adjustment of the above-mentioned that kind of enforcement and resin coating on base material; For example; In order to strengthen the adhesion with the face of resin coating bonding, implement to be used to make that chemical bond becomes possible functional group's processing, coating processing, the easy bonding coating of the physical bond that is used to soak into etc., priming paint (プ ラ イ マ one) processing, corona treatment, plasma treatment, high-energy ray treatment with irradiation, surface roughening processing, poriness processing etc. are more satisfactory.Again; As the means that are adjusted at the peeling force in the operation of separating wire grid polarization film and base material, implement to be used to import ease of solubility, be prone to decomposability, photonasty, static, magnetic force, vacuum suction, machinery are controlled etc. can be carried out comparatively ideal such as the coating of the means of outside adjustment, the processing of machinery.
On base material, cooperate plastifier, anti-oxidant, ultraviolet light absorber, dyestuff, pigment, fire retardant, have gas barrier materials with function, sticker etc. according to purpose; Perhaps with they compound duplexers that turns to, it also is more satisfactory using the material that so obtains.
As resin coating; Thickness is that the resin coating that constitutes of the formed body by light-cured resin of the scope of 0.01 μ m～3 μ m is more satisfactory, and on the surface of this resin coating, having highly is that the scope of 0.01 μ m～20 μ m, the spacing of extending at specific direction are the well-regulated concaveconvex structure of the scope of 0.01 μ m～20 μ m.Through obtaining such structure, on the sag and swell of resin coating, form metal wire and become easy.
As the characteristic of wire grid polarizer, known have: for accessing sufficient polarization property as 1/4th of the light wavelength of object when following, further, spacing is more little in the spacing of metal wire, and polarization property can improve more.
The sag and swell on resin coating surface and the spacing of metal wire are below the 20 μ m, can be apparent in the polarization characteristic of Terahertz bandwidth, and spacing is below the 150nm, also can manifest the characteristic till the visibility region, and be therefore more satisfactory.Further, spacing is below the 120nm, can have in the lump near the polarization characteristic of the short-wavelength light the 400nm; Be the words about 10nm; Can have polarization characteristic in the lump to ultraviolet region, therefore especially desirable, corresponding with the situation of dwindling spacing like this; Extinction ratio in any wavelength region may also all increases, and is therefore desirable more.
Remain the purpose that necessarily has full intensity securely from the purpose of the layer that constitutes the ambient air that comprises metal wire in order to improve optical property and for interval with metal wire; The height of the concaveconvex structure on the surface of resin coating is 0.5 times～2.0 times a scope of the spacing of this concaveconvex structure, and especially 1.0 times～2.0 times scope is more satisfactory.
The not restriction of the cross sectional shape of the concaveconvex structure on resin coating surface.These cross sectional shapes can be the sine wave shapes of trapezoidal, rectangle, square, prism-like or semicircle etc.At this, sine wave shape is meant to have the curve part that is repeated alternately to form by recess and protuberance.Curve part is that crooked curve gets final product, and for example, the shape that attenuates in the middle of the protuberance also is contained in the sine wave shape.Again, from the protuberance of the easy covering resin overlay film of dielectric layer with and the purpose of at least a portion of side, preferable case is that the end of said shape or summit, paddy portion are the shape with mild curvature bending.
The thickness of resin coating is thin more, can confirm following these desirable effects more: (a) can suppress the absorption of resin coating to light, improve transmitance; (b) can reduce volatility residual component amount in the resin coating, the pollution that causes such as prevent to ooze out; (c) reduce the crimping that cure shrinkage produced, improve the planarity of wire grid polarizer because of light-cured resin; (d) can improve the bendability of resin coating, be suppressed at the generation in the crack when making the wire grid polarizer distortion; The following of the stress (ying power ス ト レ ス) that the interlayer at resin coating and resin base material or metal fine that (e) causes for the variation by temperature, humidity produces improves the steady production rate in the manufacturing process, the reliability increase in the environment for use etc.
On the contrary; If adopt nanometer embossing make resin coating the thickness attenuation and make the words of transfer printing thing; The problem that can have following these decrease in yield: (f) the small foreign matter in sneaking into light-cured resin or swim when the small foreign matter around the production equipment is blended into transfer surface produces the frequency gets higher of lenticular defective around foreign matter; (g) owing to unfavorable conditions such as sudden and violent muscle (being coated with the り muscle) or liquid contraction, it is difficult that light-cured resin is coated on the resin base material equably, therefore produces the frequency gets higher of transfer printing defective; (h) light-cured resin is subjected to oxygen easily and hinders the frequency gets higher of the residual generation transfer printing of unreacted component defective; (i) in the operation of separating wire grid polarization film and base material, on wire grid polarization film, produce defective etc. easily.
The thickness of the resin coating that wire grid polarizer comprised of the utility model is not special to be limited, but on the purposes of the slim liquid crystal of mobile phone, is more satisfactory below the 80 μ m.The more desirable thickness of resin coating is the scope of 0.001 μ m～3 μ m, and the composition of the specific light-cured resin through the utility model and the most suitableization of transfer printing process can be adjusted into such thickness range and make.
The thinner thickness of the resin coating of the support metal wire of the wire grid polarizer of the utility model is below the 3 μ m, has therefore improved the bending with respect to wire grid polarizer, the permanance of cutting out the pressure of processing, differential contraction stress etc.Can the damage of the degree of performance that influences wire grid polarization film in the operation of separating wire grid polarization film and base material be suppressed to bottom line again.In these areas, the thickness of resin coating is desirable more below the 2 μ m.
Consider that from the fully thin flatness that makes wire grid polarization film of the resin coating this respect that improves the thickness of resin coating is also desirable more below the 1 μ m, is especially desirable below the 0.5 μ m.On the other hand, under the extremely thin situation of resin coating, the problem that exists the operability in the separation circuit of wire grid polarization film and base material to worsen, from this point consideration, the thickness of resin coating is more satisfactory more than the 0.001 μ m.
Like this; The pressure of the stress the when wire grid polarizer of the utility model is stood bending, vibration or cut-out etc.; Cut off also than being easier to, cut off line around the breaking, fracture and also can not enlarge of resin coating, therefore can cutting be shape or several millimeters square small pieces arbitrarily.Again, owing to can make the thinner thickness of resin coating, the wire grid polarizer that therefore can confirm the utility model also has high reliability for the variation of temperature, humidity.In general; Under the situation that the specific surface area of material increases, have the tendency of reliability decrease, but if under the situation of the wire grid polarizer of the utility model; Can infer; General improved in the following of resin coating, consequently increased reliability on the contrary with the stress of the interlayer generation of resin base material, metal fine owing to make the thickness attenuation of resin coating.
In order to make the thickness attenuation of resin coating, and reduce the generation of transfer printing defective, require the viscosity of employed light-cured resin low, good from the release property of pressing mold, good with the cohesiveness of resin base material.
Employed light-cured resin is preferably the composition that meets the following conditions simultaneously in the utility model; That is: (A) contains the monomer more than a kind with the scope of 20～60 weight %, and said monomer more than a kind contains acryl and/or the metering system aldehyde radical more than 3 in 1 molecule; (B) be that the composition of solid is more than the 98 weight % through the photocuring reaction be combined into; (C) viscosity 25 ℃ the time is below the 10mPas.Further be preferably, (D) contain the monomer of promising N-vinyl compound with the scope of 5～40 weight %, (E) scope with 0.1～10 weight % contains the silicon compound that comprises acryl and/or metering system aldehyde radical.(F) from the adjustment of viscosity and, the purpose of the physical property of adjustment solidfied material, further cooperate other monomer then even more ideal.(G) match ratio that is engaged to the Photoepolymerizationinitiater initiater of Photocurable resin composition is that the scope of 0.1～5.0 weight % is more satisfactory.(H) foreign matter in the Photocurable resin composition (particle) preferably removes through methods such as filtrations.During filtration, using the minimum grain size that can catch is that the following filtrator of 1 μ m is more satisfactory, the yield rate when having made the resin coating attenuation in order to improve, and the minimum grain size that can catch is that the filtrator below the 0.5 μ m is then desirable more.No matter be which kind of minimum grain size, the capturing efficiency of filtrator is preferably more than 99.9%.
