Description

  The present invention relates to a compound, an optical film, and a method for producing an optical film.

A flat panel display (FPD) includes members using optical films such as a polarizing plate and a retardation plate. Examples of the optical film include an optical film obtained by polymerizing a solution obtained by dissolving a polymerizable compound in a solvent on a supporting substrate. It is known that the phase difference (Re (λ)) of the optical film given by the light of wavelength λnm is determined by the product of the birefringence Δn and the thickness d of the film (Re (λ) = Δn). Xd). The chromatic dispersion characteristic is usually represented by a value (Re (λ) / Re (550)) obtained by dividing the phase difference value Re (λ) at a certain wavelength λ by the phase difference value Re (550) at 550 nm. (Λ) / Re (550)) is close to 1, and [Re (450) / Re (550)] <1 and [Re (650) / Re (550)]> 1. It is known that uniform polarization conversion is possible in the wavelength range shown.
For example, LC242 (manufactured by BASF) is commercially available as the polymerizable compound (Non-Patent Document 1).

Specifically, alcohols such as methanol, ethanol, ethylene glycol, isopropyl alcohol, propylene glycol, methyl cellosolve or butyl cellosolve; esters such as ethyl acetate, butyl acetate, ethylene glycol methyl ether acetate, gamma-butyrolactone or propylene glycol methyl ether acetate Solvents; ketone solvents such as acetone, methyl ethyl ketone, cyclopentanone, cyclohexanone, methyl amyl ketone or methyl isobutyl ketone; aliphatic carbonization such as pentane, hexane or heptane Containing solvent; toluene, xylene or an aromatic hydrocarbon solvent such as chlorobenzene, acetonitrile, propylene glycol monomethyl ether, tetrahydrofuran, dimethoxyethane, ethyl lactate, chloroform, phenol. These organic solvents may be used alone or in combination. In particular, the composition of the present invention is excellent in compatibility and can be dissolved in alcohols, ester solvents, ketone solvents, non-chlorine aliphatic hydrocarbon solvents, non-chlorine aromatic hydrocarbon solvents, etc., such as chloroform. Even if the halogenated hydrocarbon is not used, it can be dissolved and applied.

  The viscosity of the mixed solution containing the compound (A) and the liquid crystal compound is preferably adjusted to, for example, 10 Pa · s or less, and preferably about 0.1 to 7 Pa · s so as to be easily applied.

  Moreover, the density | concentration of the solid content in the said mixed solution is 5 to 50 weight%, for example. When the solid content is 5% or more, the optical film does not become too thin, and there is a tendency that a birefringence index necessary for optical compensation of the liquid crystal panel is provided. Moreover, since the viscosity of a mixed solution is low as it is 50% or less, since there exists a tendency for the nonuniformity to arise in the film thickness of an optical film, it is preferable.

  Subsequently, the mixed solution is applied to the supporting substrate, dried and polymerized, and the target optical film can be obtained on the supporting substrate.

[Unpolymerized film preparation process]
When a mixed solution containing the compound (A) is applied on a supporting substrate and dried, an unpolymerized film is obtained. When the unpolymerized film exhibits a liquid crystal phase such as a nematic phase, the obtained optical film has birefringence due to monodomain alignment. Since the unpolymerized film is oriented at a low temperature of about 0 to 120 ° C., preferably 25 to 80 ° C., a supporting substrate that is not necessarily sufficient with respect to heat resistance as exemplified above can be used as the orientation film. Moreover, even if it cools to about 30-10 degreeC after orientation, since it does not crystallize, handling is easy.

  The film thickness can be adjusted to give a desired phase difference by appropriately adjusting the coating amount and concentration of the mixed solution. In the case of a mixed solution in which the amount of the compound (A) is constant, the retardation value (retardation value, Re (λ)) of the obtained optical film is determined as shown in Equation (7). In order to obtain (λ), the film thickness d may be adjusted.

Re (λ) = d × Δn (λ) (7)
(In the formula, Re (λ) represents a retardation value at a wavelength λnm, d represents a film thickness, and Δn (λ) represents a birefringence at a wavelength λnm.)

  Examples of the application method to the supporting substrate include an extrusion coating method, a direct gravure coating method, a reverse gravure coating method, a CAP coating method, and a die coating method. Moreover, the method of apply | coating using coaters, such as a dip coater, a bar coater, or a spin coater, etc. are mentioned.

  As said support base material, glass, a plastic sheet, a plastic film, or a translucent film can be mentioned, for example. Examples of the translucent film include polyolefin films such as polyethylene, polypropylene and norbornene polymers, polyvinyl alcohol films, polyethylene terephthalate films, polymethacrylate films, polyacrylate films, cellulose ester films, and polyethylene naphthalate films. , Polycarbonate film, polysulfone film, polyethersulfone film, polyetherketone film, polyphenylene sulfide film, or polyphenylene oxide film.

  For example, even a process that requires the strength of the optical film, such as a bonding process, a transport process, and a storage process of the optical film of the present invention, can be easily handled without tearing by using the support substrate.

  Moreover, it is preferable to form an alignment film on a support substrate and to apply a mixed solution containing the compound (A) on the alignment film. The alignment film has solvent resistance that does not dissolve in the mixed solution when the mixed solution containing the compound (A) or the like is applied, has heat resistance during the removal of the solvent or the heat treatment of liquid crystal alignment, and is rubbed. It is preferable that peeling due to friction or the like does not occur, and it is preferable that the polymer or a composition containing the polymer is used.

  Examples of the polymer include polyamides and gelatins having an amide bond in the molecule, polyimides having an imide bond in the molecule, and polyamic acid, polyvinyl alcohol, alkyl-modified polyvinyl alcohol, polyacrylamide, polyoxazole, which are hydrolysates thereof. Mention may be made of polymers such as polyethyleneimine, polystyrene, polyvinylpyrrolidone, polyacrylic acid or polyacrylates. These polymers may be used alone, or two or more kinds thereof may be mixed or copolymerized. These polymers can be easily obtained by polycondensation such as dehydration and deamination, chain polymerization such as radical polymerization, anion polymerization, and cation polymerization, coordination polymerization, and ring-opening polymerization.

  Further, these polymers can be applied after being dissolved in a solvent. The solvent is not particularly limited, but specifically, alcohol such as water, methanol, ethanol, ethylene glycol, isopropyl alcohol, propylene glycol, methyl cellosolve or butyl cellosolve; ethyl acetate, butyl acetate, ethylene glycol methyl ether acetate, gamma Ester solvents such as butyrolactone or propylene glycol methyl ether acetate; ketone solvents such as acetone, methyl ethyl ketone, cyclopentanone, cyclohexanone, methyl amyl ketone or methyl isobutyl ketone; aliphatic hydrocarbon solvents such as pentane, hexane or heptane; toluene , Aromatic hydrocarbon solvents such as xylene or chlorobenzene, acetonitrile, propylene glycol monomethyl ether, tetrahydrofuran , Dimethoxyethane, ethyl lactate, chloroform and the like. These organic solvents may be used alone or in combination.

  In order to form the alignment film, a commercially available alignment film material may be used as it is. Examples of commercially available alignment film materials include Sunever (registered trademark, manufactured by Nissan Chemical Industries, Ltd.) or Optmer (registered trademark, manufactured by JSR Corporation).

  If such an alignment film is used, it is not necessary to control the refractive index by stretching, so that in-plane variation in birefringence is reduced. Therefore, it is possible to provide a large optical film that can cope with an increase in the size of the flat panel display (FPD) on the support substrate.

  As a method for forming an alignment film on the support substrate, for example, a commercially available alignment film material or a compound serving as an alignment film material is applied as a solution on the support substrate, and then annealed, An alignment film can be formed on the support substrate.

  The thickness of the alignment film thus obtained is, for example, 10 nm to 10000 nm, preferably 10 nm to 1000 nm. If it is the said range, a compound (A) etc. can be orientated on a desired angle on this alignment film.

  Further, these alignment films can be rubbed or irradiated with polarized UV rays as necessary. Thus, the compound (A) or the like can be oriented in a desired direction.

  As a method for rubbing the alignment film, for example, a method in which a rubbing cloth is wound and a rotating rubbing roll is placed on a stage and brought into contact with the alignment film being conveyed can be used.

  As described above, in the unpolymerized film preparation step, the unpolymerized film (liquid crystal layer) is laminated on the alignment film laminated on an arbitrary support substrate. Therefore, the production cost can be reduced as compared with a method of manufacturing a liquid crystal cell and injecting a liquid crystal compound into the liquid crystal cell. Furthermore, it is possible to produce a film using a roll film.

  The solvent may be dried while the polymerization proceeds, but it is preferable from the viewpoint of film formability that most of the solvent is dried before the polymerization.

  Examples of the solvent drying method include natural drying, ventilation drying, and vacuum drying. The specific heating temperature is preferably 10 to 120 ° C, more preferably 25 to 80 ° C. In addition, the heating time is preferably 10 seconds to 60 minutes, and more preferably 30 seconds to 30 minutes. As long as the heating temperature and the heating time are within the above ranges, a supporting substrate that does not necessarily have sufficient heat resistance can be used as the supporting substrate.

[Unpolymerized film polymerization process]
In the unpolymerized film polymerization step, the unpolymerized film obtained in the unpolymerized film preparation step is polymerized and cured. Thereby, a film in which the orientation of the compound (A) is fixed, that is, a polymerized film is obtained. Therefore, it is possible to produce a polymer film having a small change in refractive index in the plane direction of the film and a large change in refractive index in the normal direction of the film.

The method for polymerizing the unpolymerized film is determined according to the types of the liquid crystal compound and the compound (A). If P ¹ and / or P ² contained in the compound (A) and the polymerizable group contained in the liquid crystal compound are photopolymerizable, photopolymerization is performed, and if the polymerizable group is thermopolymerizable, thermal polymerization is performed. Unpolymerized films can be polymerized. In the present invention, it is particularly preferable to polymerize an unpolymerized film by photopolymerization. According to photopolymerization, an unpolymerized film can be polymerized at a low temperature, so that the selection range of the heat resistance of the supporting substrate is widened. In addition, it is easy to manufacture industrially. Photopolymerization is also preferred from the viewpoint of film formability. Photopolymerization is performed by irradiating an unpolymerized film with visible light, ultraviolet light, or laser light. From the viewpoint of handleability, the irradiation with ultraviolet light that is particularly preferable may be performed while heating the compound (A) to a temperature at which the liquid crystal phase is taken. At this time, the polymerized film can be patterned by masking or the like.

  Since the optical film of the present invention has good adhesion between the alignment film and the optical film, the production of the optical film is easy.

  Furthermore, the optical film of the present invention is a thin film as compared with a stretched film that gives a phase difference by stretching a polymer.

  In the manufacturing method of the optical film of this invention, the process of peeling a support base material may be included following the said process. By setting it as such a structure, the laminated body obtained becomes a film which consists of an oriented film and an optical film. Moreover, in addition to the process of peeling the said support base material, the process of peeling an alignment film may be further included. By setting it as such a structure, an optical film can be obtained.

  The optical film thus obtained is excellent in transparency and used as various display films. As described above, the thickness of the layer to be formed varies depending on the retardation value of the obtained optical film. In the present invention, the thickness is preferably 0.1 to 10 μm, and more preferably 0.5 to 3 μm from the viewpoint of reducing photoelasticity.

  In the case where the alignment film is used and has birefringence, for example, the retardation value is about 50 to 500 nm, preferably 100 to 300 nm.

  Such a thin film capable of uniform polarization conversion in a wider wavelength range can be used as an optical compensation film in all liquid crystal panels and FPDs such as organic EL.

  In order to use the optical film of the present invention as a broadband λ / 4 plate or λ / 2 plate, the content of the structural unit derived from the compound (A) is appropriately selected. In the case of a λ / 4 plate, the film thickness may be adjusted to Re (550) of the obtained optical film of 113 to 163 nm, preferably 135 to 140 nm, particularly preferably about 137.5 nm. In this case, the film thickness may be adjusted so that Re (550) of the obtained optical film is 250 to 300 nm, preferably 273 to 277 nm, particularly preferably about 275 nm.

  In order to use the optical film of the present invention as an optical film for a VA (vertical alignment) mode, the content of the structural unit derived from the compound (A) is appropriately selected. The film thickness may be adjusted so that Re (550) is preferably 40 to 100 nm, more preferably about 60 to 80 nm.

  By adding a small amount of the compound (A), the wavelength dispersion characteristic of the optical film can be shifted to a value close to 1, and the desired wavelength dispersion characteristic can be prepared by a simple method.

  The optical film of the present invention is used for an antireflection film such as an anti-reflection (AR) film, a polarizing film, a retardation film, an elliptically polarizing film, a viewing angle widening film, or an optical compensation film for compensating a viewing angle of a transmissive liquid crystal display. can do. Moreover, although the optical film of this invention shows the outstanding optical characteristic even if it is 1 sheet, you may laminate | stack several sheets.

  Moreover, you may combine with another film. Specifically, an elliptically polarizing plate in which the optical film of the present invention is bonded to a polarizing film, a broadband circularly polarizing plate in which the optical film of the present invention is further bonded to the elliptical polarizing plate as a broadband λ / 4 plate, and the like. It is done.

  Since the optical film of the present invention can be formed by coating on an alignment film and polymerizing by irradiation with ultraviolet rays, as shown in FIG. / 2 optical film can be formed.

FIG. 1 is a schematic view showing a color filter 1 according to the present invention.
The color filter 1 is a color filter in which the optical film 2 of the present invention is formed on the color filter layer 4 via an alignment film 3.

An example of a method for manufacturing the color filter 1 having the above configuration will be described. First, an alignment polymer is printed on the color filter layer 4 and a rubbing process is performed to form the alignment film 3.
Next, a mixed solution containing the compound (A) is prepared on the obtained alignment film 3 so as to have a desired wavelength dispersion characteristic, and applied while adjusting the thickness so as to obtain a desired retardation value. Film 2 is formed.

  On the other hand, if the color filter 1 is used, a thin liquid crystal display device with a reduced number of optical films 2 can be manufactured. As an example, there is a thin liquid crystal display device formed on the liquid crystal layer side of at least one substrate in a liquid crystal display element in which a liquid crystal layer is sandwiched and formed between a pair of substrates as shown in FIG.

FIG. 2 is a schematic view showing a liquid crystal display device 5 according to the present invention.
In the liquid crystal display device 5 shown in FIG. 2, a substrate 7 facing a backlight such as a glass substrate is fixed on a polarizing plate 6 via an adhesive, and a color filter layer 4 ′ formed on the substrate 7. An optical film 2 ′ is formed thereon via an alignment film 3 ′. Further, a counter electrode 8 is formed on the optical film 2 ′, and a liquid crystal phase 9 is formed on the counter electrode 8. On the backlight side, a substrate 11 such as a glass substrate is fixed to the polarizing plate 10 with an adhesive, and a thin film transistor (TFT) and an insulating layer 12 for actively driving a liquid crystal layer are formed on the substrate 11. Further, a transparent electrode 13 and / or a reflective electrode 13 ′ made of Ag, Al, or ITO (Indium Tin Oxide) is formed on the TFT. The configuration of the liquid crystal display device 5 shown in FIG. 2 can reduce the number of optical films as compared with a conventional liquid crystal display device, and enables the manufacture of a thinner liquid crystal display device.

Below, an example of the manufacturing method of the liquid crystal display device 5 in which color filter 1 'was formed in the liquid crystal layer side of one board | substrate is described. On the substrate on the backlight side, a gate electrode made of Mo, MoW or the like, a gate insulating film, and amorphous silicon are deposited and patterned on a borosilicate glass, and the amorphous silicon is crystallized by annealing with an excimer laser. A semiconductor thin film can be formed, and then n-channel and p-channel TFTs can be formed by doping P, B, and the like in regions on both sides of the gate electrode. By further forming an insulating film made of SiO _2, the backlight side of the substrate is obtained. Further, by sputtering ITO on the backlight side substrate 11, the transparent electrode 13 for the total transmission display device can be laminated on the backlight side substrate. Similarly, a reflective electrode 13 'for a total reflection display device can be obtained by using Ag, Al or the like instead of ITO. Further, a backlight electrode for a transflective liquid crystal display device can be obtained by appropriately combining a reflective electrode and a transparent electrode.

  On the other hand, the color filter layer 4 ′ is formed on the opposing substrate 7. By using R, G, and B color filters in combination, a full-color liquid crystal display device can be obtained. Next, an alignment polymer is applied on the color filter layer 4 'and rubbed to form an alignment film 3'. A composition containing the compound (A) according to the present invention is applied onto the alignment film 3 ', and polymerized to form an optical film 2' by irradiation with ultraviolet rays while heating to a temperature range that takes a liquid crystal phase. After forming the optical film, the counter electrode 8 can be formed by sputtering ITO. Further, an alignment film is formed on the counter electrode, the liquid crystal phase 9 is formed, and finally the liquid crystal display device 5 can be produced by assembling together with the substrate on the backlight side. Further, the value of [Re (450) / Re (550)] and [Re (650) / Re (550)] of the compound (A) of the present invention is close to 1 or less than 1, so that the composition is changed. Thus, desired wavelength dispersion characteristics can be obtained, and the retardation value can be controlled from the film thickness, so that the lamination of the optical film can also be omitted.

  Furthermore, the optical film of the present invention can also be used for a retardation plate of a reflective liquid crystal display and an organic EL display, and an FPD including the retardation plate and the optical film. The FPD is not particularly limited, and examples thereof include a liquid crystal display (LCD) and an organic EL.

Thus, the film according to the present invention can be used in a wide range of applications. For example, a polarizing plate formed by laminating the optical film and the polarizing film according to the present invention and an FPD including the polarizing plate will be described below. The polarizing plate according to the present invention is a film having a polarizing function, that is, one side of the polarizing film. Alternatively, it is obtained by laminating the optical film directly on both sides or using an adhesive or a pressure-sensitive adhesive. In the following description of FIGS. 3 to 5, the adhesive and the pressure-sensitive adhesive may be collectively referred to as an adhesive.

  The polarizing plate of the present invention is a laminate of a polarizing film and a laminate containing the optical film of the present invention. Instead of the laminated body 14 and the laminated body 14 ′, an optical film 18 in which the supporting base material 16 and the alignment film 17 are peeled off from the laminated body 14 may be used, or the supporting base material 16 is peeled off from the laminated body 14. A film composed of the alignment film 17 and the optical film 18 may be used.

  The polarizing plate of the present invention may be formed by laminating a plurality of laminates, and the plurality of laminates may be all the same or different.

A 2% by weight aqueous solution of polyvinyl alcohol (polyvinyl alcohol 1000 completely saponified type, manufactured by Wako Pure Chemical Industries, Ltd.) was applied to a glass substrate, and after drying, a film having a thickness of 89 nm was formed. Subsequently, the surface of the obtained film was subjected to a rubbing treatment, and a coating solution having the composition shown in Table 6 was applied to the surface subjected to the rubbing treatment by a spin coating method and dried. Thereafter, ultraviolet rays were irradiated. Thereby, the optical film was able to be created on the glass substrate.

In Table 6, “% by weight” in the tables other than the solvent means “% by weight” with the coating solution being 100% by weight.

LC242: liquid crystal compound photopolymerizable initiator commercially available from BASF: Irgacure 907, Irgacure 819 (manufactured by Ciba Specialty Chemicals)
Leveling agent: BYK361N (manufactured by Big Chemie Japan)

<Measurement of optical properties>
The front retardation value of the produced optical film was measured using a measuring machine (KOBRA-WR, manufactured by Oji Scientific Instruments). In addition, since the glass substrate used for the base material has no birefringence, the front retardation value of the optical film produced on the glass substrate can be obtained by measuring the film with the glass substrate with a measuring machine. . The obtained optically measured front phase difference values were measured at wavelengths of 447.3 nm, 546.9 nm, and 627.8 nm, respectively, and [Re (447.3) / Re (546.9)] (referred to as α). And [Re (627.8) / Re (546.9)] (referred to as β) were calculated. Moreover, the film thickness (micrometer) of the part originating in an optical film was measured using the laser microscope (LEXT, Olympus company make). The results are shown in Table 7. Δn was calculated by dividing the value of Re (546.9) by the film thickness.

The optical films obtained in Examples 12 to 28 were compared with Comparative Example 3 [Re (447.
3) / Re (546.9)] (α in the table) was closer to 1 or less than 1. Further, the value of [Re (627.8) / Re (546.9)] (β in the table) was closer to 1 or 1 or more. That is, since the wavelength dependency of the refractive index is small or so-called reverse wavelength dispersion is exhibited, when used in a liquid crystal panel, it has excellent optical compensation characteristics.

  According to the compound of the present invention, an optical film capable of uniform polarization conversion in a wide wavelength range can be provided.
