     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a fluorine-containing copolymer, a composition, an optical film, a liquid crystal film, a hardcoat film, and a polarizing plate. 
     2. Description of the Related Art 
     Polymer materials have been increasingly used in many fields in recent years. Along with this, the characteristics of a polymer as a matrix as well as the properties and states of a surface and an interface of the polymer have been increasingly important according to each field. 
     Optical films such as an optical compensation sheet and a phase difference film have been used in various image display devices for the purpose of solving image coloration, widening a viewing angle, and the like. A stretched birefringent film has been used as the optical film, but it has recently been proposed to use a film (liquid crystal film) having an optically anisotropic layer consisting of a liquid crystal compound instead of the stretched birefringent film. 
     For example, it has been proposed to use an optical film having an optically anisotropic layer containing a predetermined fluoroaliphatic group-containing copolymer in order to display an image having high display quality while not generating unevenness (JP2004-198511A). 
     On the other hand, in recent years, functions required for optical films have been increasingly more sophisticated. It has also been proposed to combine layers having optical functions to constitute various optical laminates, and in a case of combining these layers, there is an increasing demand for not causing uneven coating thickness, defects, cissing-like failures, and the like. 
     SUMMARY OF THE INVENTION 
     In an optically anisotropic layer formed with a liquid crystal compound, the liquid crystal compound is required to be uniformly aligned so as not to generate alignment defects (satisfying such a requirement will hereinafter be also referred to as having excellent “aligning properties”). In addition, there is also a demand for homogeneity with no unevenness or defects. 
     Therefore, an object of the present invention is to provide a fluorine-containing polymer capable of forming a film having excellent aligning properties and homogeneity, a composition containing the fluorine-containing polymer, and an optical film, a liquid crystal film, a hardcoat film, and a polarizing plate, each including a layer formed from the composition. 
     The present inventors have conducted extensive studies to accomplish the object, and as a result, they have found that the object of the present invention is accomplished by manufacturing an optical film using a composition including a predetermined fluorine-containing polymer. 
     That is, the present inventors have found that it is possible to accomplish the object by the following configurations.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Hereinafter, the present invention will be described in detail. 
     The following description of the constitutional requirements is made based on representative embodiments of the present invention in some cases, but it should not be construed that the present invention is limited to such embodiments. 
     Furthermore, in the present specification, a numerical range expressed using “to” means a range that includes the preceding and succeeding numerical values of “to” as the lower limit value and the upper limit value, respectively. 
     In addition, in the present specification, the bonding direction of a divalent group (for example, —CO—O—) described is not particularly limited, and for example, in a case where D1 in General Formula (W) which will be described later is —CO—O—, D1 may be either *1—CO—O—*2 or *1—O—CO—*2, in which *1 represents a position bonding to the Ar side and *2 represents a position bonding to the G1 side. 
     In the present specification, (meth)acrylate represents acrylate or methacrylate. In addition, (meth)acrylic acid represents acrylic acid or methacrylic acid. A (meth)acryloyl group represents a methacryloyl group or an acryloyl group. 
     In citations for a group (atomic group) in the present specification, in a case where the group is denoted without specifying whether it is substituted or unsubstituted, the group includes both a group not having a substituent and a group having a substituent. For example, an “alkyl group” includes not only an alkyl group not having a substituent (unsubstituted alkyl group), but also an alkyl group having a substituent (substituted alkyl group). In addition, an “organic group” in the present specification refers to a group having at least one carbon atom. 
     Moreover, in the present specification, the type of the substituent, the position of the substituent, and the number of the substituents in a case of referring to “which may have a substituent” are not particularly limited. The number of the substituents may be, for example, one, two, three, or the like. Examples of the substituent include a monovalent non-metal atomic group excluding a hydrogen atom, and can be selected from, for example, the following substituent group T. 
     (Substituent T) 
     Examples of the substituent T include a halogen atom such as a fluorine atom, a chlorine atom, a bromine atom, and an iodine atom; an alkoxy group such as a methoxy group, an ethoxy group, and a tert-butoxy group; an aryloxy group such as a phenoxy group and a p-tolyloxy group; an alkoxycarbonyl group such as a methoxycarbonyl group, a butoxycarbonyl group, and a phenoxycarbonyl group; an acyloxy group such as an acetoxy group, a propionyloxy group, and a benzoyloxy group; an acyl group such as an acetyl group, a benzoyl group, an isobutyryl group, an acryloyl group, a methacryloyl group, and a methoxalyl group; an alkylsulfanyl group such as a methylsulfanyl group and a tert-butylsulfanyl group; an arylsulfanyl group such as a phenylsulfanyl group and a p-tolylsulfanyl group; an alkyl group; a cycloalkyl group; an aryl group; a heteroaryl group; a hydroxyl group; a carboxy group; a formyl group; a sulfo group; a cyano group; an alkylaminocarbonyl group; an arylaminocarbonyl group; a sulfonamide group; a silyl group; an amino group; a monoalkylamino group; a dialkylamino group; an arylamino group; and a combination thereof. 
     A reason why the film including the fluorine-containing polymer of an embodiment of the present invention has homogeneity and has excellent aligning properties in a case of being made into a liquid crystal film has not been clarified in detail, but is presumed to be as follows by the present inventors. 
     Since the fluorine-containing polymer of the embodiment of the present invention has a branched structure having a plurality of branched aliphatic hydrocarbon groups having a fluorine atom in branches, as represented by General Formulae (I) to (III), the fluorine moieties can be efficiently localized on an air interface side and the copolymerization components can be efficiently localized on a matrix resin forming component (curable component) side in the composition, whereby a compatibility between the fluorine-containing polymer of the embodiment of the present invention and the matrix resin forming component is improved. It is presumed that such a configuration causes aggregation of the fluorine-containing polymer of the embodiment of the present invention in the composition including the fluorine-containing polymer of the embodiment of the present invention to be less likely to occur, whereby the aligning properties of the liquid crystal compound are improved. 
     In addition, due to the branched structure, the transferability of the fluorine-containing polymer onto a surface of the coating film is improved. It is presumed that since the surface tension of the composition (coating film) is lowered by adding such a fluorine-containing polymer to the composition, the wettability (homogeneous coating properties) of the composition with respect to a substrate during coating is improved, whereby a film having excellent homogeneity with less unevenness and defects can be obtained.

     The fluorine-containing polymer of the embodiment of the present invention preferably has a structure derived from a liquid crystal compound. 
     Examples of the structure derived from the liquid crystal compound include a partial structure formed by a radical polymerization of a compound having a mesogenic group derived from at least one liquid crystal compound selected from a rod-like liquid crystal compound and a disk-like liquid crystal compound, and two or more polymerizable groups. In a case where the fluorine-containing polymer of the embodiment of the present invention has such a partial structure, the fluorine-containing polymer is branched. That is, the polymerizable group derived from the liquid crystal compound serves as a branch point. 
     The partial structure is preferably introduced into the fluorine-containing polymer of the embodiment of the present invention as the repeating unit having a structure derived from a liquid crystal compound. 
     The partial structure includes a mesogen structure derived from a liquid crystal compound. Therefore, in a case where the fluorine-containing polymer of the embodiment of the present invention includes the partial structure, the compatibility between the polymerizable liquid crystal compound and the fluorine-containing polymer in the liquid crystal composition is improved. As a result, the wettability of the liquid crystal composition with respect to the substrate is further improved and cissing during application of the liquid crystal composition can be suppressed, whereby a more homogeneous film can be obtained. In particular, in a case where the content of the polymerizable liquid crystal compound in the liquid crystal composition is high, this effect is more remarkably expressed. 
     Here, the expression that the polymer is “branched” means that the polymer has a three-dimensional crosslinking structure and at least one polymerization initiator fragment is incorporated at a terminal. A polymerization initiator fragment differs depending on the structure of a polymerization initiator structure used in polymerization of the polymer, but it can be confirmed that the polymer fragment is incorporated into the polymer by a method such as nuclear magnetic resonance (NMR) spectrum measurement, infrared (IR) spectrum measurement, mass spectrometry measurement, or element analysis measurement.

The partial structure is preferably introduced into the fluorine-containing polymer of the embodiment of the present invention as the repeating unit having a structure derived from a liquid crystal compound. 
     The partial structure includes a mesogen structure derived from a liquid crystal compound. Therefore, in a case where the fluorine-containing polymer of the embodiment of the present invention includes the partial structure, the compatibility between the polymerizable liquid crystal compound and the fluorine-containing polymer in the liquid crystal composition is improved. As a result, the wettability of the liquid crystal composition with respect to the substrate is further improved and cissing during application of the liquid crystal composition can be suppressed, whereby a more homogeneous film can be obtained. In particular, in a case where the content of the polymerizable liquid crystal compound in the liquid crystal composition is high, this effect is more remarkably expressed.

     Composition 
     Next, a composition including the fluorine-containing polymer of the embodiment of the present invention (hereinafter also simply referred to as “the composition of an embodiment of the present invention”) will be described. 
     The composition of the embodiment of the present invention may contain a component other than the fluorine-containing copolymer, and preferably contains a compound for forming a film, and a solvent, in addition to the fluorine-containing polymer. In particular, by incorporating a polymerizable liquid crystal compound as the compound for forming a film, the composition can be used as a composition (coating liquid) for forming an optically anisotropic layer. 
     The liquid crystal composition, which is one of suitable aspects of the composition of the embodiment of the present invention, includes at least the fluorine-containing polymer of the embodiment of the present invention and a polymerizable liquid crystal compound. 
     Hereinafter, the components included in the liquid crystal composition will be described. 
     Fluorine-Containing Polymer 
     The liquid crystal composition includes the fluorine-containing polymer of the embodiment of the present invention. 
     The content of the fluorine-containing polymer of the embodiment of the present invention is preferably 0.003% to 10% by mass, more preferably 0.005% to 5% by mass, and still more preferably 0.01% to 3% by mass with respect to the total mass of the liquid crystal composition. In a case where the content of the fluorine-containing polymer of the embodiment of the present invention is 0.003% by mass or more, a film having more excellent homogeneity can be obtained. In a case where the content of the fluorine-containing polymer of the embodiment of the present invention is 10% by mass or less, the aligning properties of the liquid crystal component included in the film are more excellent. 
     Polymerizable Liquid Crystal Compound 
     The liquid crystal composition includes a polymerizable liquid crystal compound. 
     The polymerizable liquid crystal compound is a liquid crystal compound having at least one or more polymerizable groups. 
     Generally, the liquid crystal compounds can be classified into a rod-like type and a disk-like type, depending on the shape. Further, the respective types can further be classified into a low-molecular-weight type and a high-molecular-weight type. The high-molecular-weight compound generally refers to a polymer having a degree of polymerization of 100 or more (Kobunshi Butsuri Souten-I Dainamikusu (Polymer Physics and Phase Transition Dynamics), written by Masao Doi, p. 2, Iwanami Shoten, Publishers, 1992). 
     Any liquid crystal compound can be used as the polymerizable liquid crystal compound as long as it has a polymerizable group, and among those, the rod-like polymerizable liquid crystal compound or the disk-like polymerizable liquid crystal compound is preferably used, and the rod-like polymerizable liquid crystal compound is more preferably used. 
     In addition, the liquid crystal composition may further include a liquid crystal compound other than the polymerizable liquid crystal compound. 
     The polymerizable liquid crystal compound preferably has two or more polymerizable groups in one molecule. In addition, in a case where two or more polymerizable liquid crystal compounds are used, it is preferable that at least one of the polymerizable liquid crystal compounds has two or more polymerizable groups in one molecule. 
     Moreover, after fixing the liquid crystal compound by the polymerization, it is already not necessary to exhibit the liquid crystallinity, but a layer thus formed is conveniently referred to as a liquid crystal layer in some cases. The liquid crystal layer is preferably a layer in which the aligned liquid crystal compound is fixed while the alignment state is maintained. 
     The type of the polymerizable group contained in the polymerizable liquid crystal compound is not particularly limited, a functional group capable of performing an addition polymerization reaction is preferable, and an ethylenically unsaturated polymerizable group or a ring polymerizable group is preferable. More specifically, a (meth)acryloyl group, a vinyl group, a styryl group, an allyl group, an epoxy group, or an oxetane group is preferable, and from the viewpoint of a high rate in the polymerization reaction rate, the (meth)acryloyl group is more preferable. 
     Examples of the rod-like polymerizable liquid crystal compound include the compounds described in claim  1  of JP1999-513019A (JP-H11-513019A) and paragraphs [0026] to [0098] of JP2005-289980A. Examples of the disk-like polymerizable liquid crystal compound include the compounds described in paragraphs [0020] to [0067] of JP2007-108732A and the compounds described in paragraphs [0013] to [0108] of JP2010-244038A. 
     Moreover, examples of the rod-like polymerizable liquid crystal compound include a liquid crystal compound capable of expressing a smectic phase, and include, for example, the compounds described in JP2016-51178A, JP2008-214269A, JP2008-19240A, and JP2006-276821A. 
     Furthermore, as the rod-like polymerizable liquid crystal compound, a polymerizable liquid crystal compound having a maximum absorption wavelength in a wavelength range of 330 to 380 nm is preferable. 
     In addition, the rod-like polymerizable liquid crystal compound is a preferably polymerizable liquid crystal compound having reverse wavelength dispersibility. 
     Here, the polymerizable liquid crystal compound having “reverse wavelength dispersibility” in the present specification means that in a case where an in-plane retardation value (Re) at a specific wavelength (visible light range) of a phase difference film (an optically anisotropic layer and the like) manufactured using the polymerizable liquid crystal compound is measured, Re is equal to or higher as the measurement wavelength is increased.

     Moreover, suitable examples of the compound represented by Formula (W) include compounds represented by Formulae (1) to (22), and specific examples thereof include the compounds having side chain structures shown in Tables 1 to 3 below as K (side chain structure) in Formulae (1) to (22). 
     Furthermore, in Tables 1 to 3 below, “*” shown in the side chain structure of K represents a bonding position to an aromatic ring. 
     In addition, in the side chain structures shown in 2-2 in Table 2 below and 3-2 in Table 3 below, a group adjacent to each of the acryloyloxy group and the methacryloyl group represents a propylene group (a group in which a methyl group is substituted with an ethylene group), and represents a mixture of regioisomers in which the positions of the methyl groups are different.

     Liquid Crystal Film 
     The liquid crystal film of an embodiment of the present invention is an optical film having a layer (optically anisotropic layer) formed from the above-mentioned liquid crystal composition. 
     Forming Method 
     A method for forming an optically anisotropic layer formed of the above-mentioned liquid crystal composition is not particularly limited, and for example, a liquid crystal film having an optically anisotropic layer can be formed by directly applying a liquid crystal composition onto a support to form a coating film, and subjecting the obtained coating film to an alignment forming treatment such as heating and/or cooling, and a curing treatment (irradiation with ultraviolet rays (light irradiation treatment) or a heating treatment). In addition, the optically anisotropic layer may also be formed by applying a liquid crystal composition onto an alignment film which will be described later and subjecting the film to the same treatment as the above-mentioned treatment. 
     Application of the liquid crystal composition can be carried out by a known method (for example, a wire bar coating method, an extrusion coating method, a direct gravure coating method, a reverse gravure coating method, and a die coating method). 
     In the present invention, the thickness of the optically anisotropic layer is not particularly limited, but is preferably 0.1 to 10 μm, and more preferably 0.5 to 5 μm. 
     Aligning Properties and Optical Characteristics of Optically Anisotropic Layer 
     The optically anisotropic layer can be aligned in various alignment states such as horizontal alignment, vertical alignment, tilt alignment, hybrid alignment, random homogeneous alignment, and cholesteric alignment, and can be imparted with various optical characteristics by appropriately selecting the optical anisotropy and the alignment state of the polymerizable liquid crystal compound. 
     For example, in a preferred aspect, the optically anisotropic layer may serve as a positive A-plate. The positive A-plate can be obtained by horizontally aligning a rod-like polymerizable liquid crystal compound. Further, in a case where the in-plane retardation Re(550) is set to 100 to 160 nm (preferably 120 to 150 nm), the plate can be suitably used as a positive uniaxial λ/4 plate. In addition, by setting Re(550) to be in the range of 250 to 300 nm, the plate can be used as a positive uniaxial λ/2 plate. Here, Re(550) represents an in-plane retardation at a wavelength of 550 nm of the optically anisotropic layer. The in-plane retardation value can be measured using AxoScan OPMF-1 (manufactured by Opto Science, Inc.). 
     In addition, in one preferred aspect, the optically anisotropic layer may also serve as a positive C-plate. 
     The positive C-plate can be obtained by vertically aligning a rod-like polymerizable liquid crystal compound. The thickness-direction retardation Rth(550) is, for example, 20 to 200 nm, and is preferably 50 to 120 nm from the viewpoint of imparting various optical compensation functions and/or a viewing angle enhancing function, and the like. 
     In addition, the optically anisotropic layer may be either a negative A-plate or a negative C-plate. Incidentally, by cholesterically aligning the liquid crystal layer, it is also possible to impart the layer with optical rotation, wavelength selective reflectivity, and the like. 
     Moreover, in the present specification, the A-plate is defined as follows. 
     The A-plate encompasses two kinds of plates, that is, a positive A-plate and a negative A-plate, and in a case where a refractive index in the slow axis direction in the film plane (a direction in which the refractive index becomes a maximum in the plane) is defined as nx, a refractive index in the direction in-plane orthogonal to the in-plane slow axis is defined as ny, and a refractive index in the thickness direction is defined as nz, the positive A-plate satisfies a relationship of Formula (A1) and the negative A-plate satisfies a relationship of Formula (A2). In addition, in the positive A-plate, Rth represents a negative value, and in the negative A-plate, Rth represents a positive value. 
       nx&gt;ny≈nz   Formula (A1)
 
       ny&lt;nx≈nz   Formula (A2)
 
     Furthermore, “≈” encompasses a case where both sides are completely the same as each other as well as a case where the both sides are substantially the same as each other. With regard to the expression, “substantially the same”, for example, a case where (ny−nz)×d (in which d is the thickness of a film) is −10 to 10 nm, and preferably −5 to 5 nm is also encompassed by “ny≈nz”, and a case where (nx−nz)×d is −10 to 10 nm, and preferably −5 to 5 nm is also encompassed by “nx≈nz”. 
     The C-plate encompasses two kinds of plates, that is, a positive C-plate and a negative C-plate, the positive C-plate satisfies the relationship of Formula (C1), and the negative C-plate satisfies the relationship of Formula (C2). Furthermore, in the positive C-plate, Rth represents a negative value, and in the negative C-plate, Rth represents a positive value. 
       nz&gt;nx≈ny   Formula (C1)
 
       nz&lt;nx≈ny   Formula (C2)
 
     Furthermore, “≈” encompasses a case where both sides are completely the same as each other as well as a case where the both sides are substantially the same as each other. With regard to the expression, “substantially the same”, for example, a case where (nx−ny)×d (in which d is the thickness of a film) is 0 to 10 nm, and preferably 0 to 5 nm is also encompassed by “nx≈ny”. 
     Moreover, it is possible to appropriately adjust the optically anisotropic wavelength dispersibility by adjusting the polymerizable liquid crystal compound, the other components used in the liquid crystal composition, and the like. 
     The optically anisotropic layer preferably exhibits reverse wavelength dispersibility. As a specific example of the optically anisotropic layer, it is preferable that the optically anisotropic layer satisfies Formula (II) as a uniaxial phase difference layer. 
       Δn(450)/Δn(550)&lt;1.00   (II)
 
     Here, in Formula (II), Δn(450) represents a refractive index difference between the refractive index in the direction such that the refractive index is maximum at a wavelength of 450 nm of the optically anisotropic layer and the refractive index in a direction orthogonal thereto, and Δn(550) represents a refractive index difference between the refractive index in the direction such that the refractive index is maximum at a wavelength of 550 nm of the optically anisotropic layer and the refractive index in a direction orthogonal thereto. 
     Support 
     The liquid crystal film of the embodiment of the present invention preferably has a support as described above. The support is not particularly limited and various known materials can be used. Among those, a long polymer film is preferable from the viewpoint that it enables continuous production. 
     Examples of the polymer film include polymer films obtained by forming polyolefin cyclic olefin-based resins such as polypropylene and a norbornene-based polymer; polyvinyl alcohols; polyester resins such as polyethylene terephthalate, polybutylene terephthalate, and polyethylene naphthalate; polymethacrylic acid esters·polyacrylic acid esters such as polymethyl methacrylate; cellulose esters such as triacetyl cellulose, diacetyl cellulose, and cellulose acetate propionate; polyethylene naphthalate; polycarbonates; or a copolymer thereof into films. These polymer films can be appropriately selected on the basis of the viewpoints of an elastic modulus, a flexural modulus, a parallel light ray transmittance, a haze, optical anisotropy, optical isotropy, easy peelability, easy adhesion, and the like. 
     In the present invention, from the viewpoint of obtaining an optically anisotropic layer having uniform alignment, the coating-side surface of the support is preferably smooth and the surface roughness Ra is preferably 3 to 50 nm in a case of forming an optically anisotropic layer by directly applying a liquid crystal composition onto a support. 
     In addition, in a case where an alignment layer which will be described later is provided on a support and a liquid crystal composition is applied onto the alignment layer to form an optically anisotropic layer, the surface of the alignment layer only needs to be smooth and the surface roughness Ra is preferably 3 to 50 nm. It is also possible that an interlayer which will be described later, or the like is provided and a surface roughness thereof is adjusted. 
     Moreover, in use of the long polymer film, from the viewpoint of preventing a phenomenon of shape transfer and blocking between the film surfaces in the state of a wound body formed by winding a liquid crystal film produced, a surface on the opposite side to a surface of the support, on which the liquid crystal composition is applied, can be subjected to an anti-blocking treatment, a mat treatment, or the like. In addition, knurling may be provided on an end of the film. 
     Moreover, it is also preferable that the support is provided so as to be peeled. That is, it is also preferable that the support is peelably disposed from an adjacent layer in the liquid crystal film. Here, in a case where an optically anisotropic layer is directly arranged on the support, it is preferable that peeling can occur at the interface between the support and the optically anisotropic layer. In addition, in a case where an alignment layer which will be described later and/or the other layers (interlayer) are arranged between the support and the optically anisotropic layer, it is preferable that peeling can occur at any interface between the support and the optically anisotropic layer or within the layer. 
     Alignment Layer 
     The liquid crystal film of the embodiment of the present invention may have an alignment layer, as desired. From the viewpoint that an optically anisotropic layer having more excellent aligning properties is easily obtained, it is preferable that an alignment layer is provided on a support and the above-mentioned optically anisotropic layer is further provided on the alignment layer. That is, it is preferable that the liquid crystal film of the embodiment of the present invention has a photoalignment layer between the support and the optically anisotropic layer. 
     Various known alignment layers can be used as the alignment layer, and examples thereof include a rubbing film (rubbing alignment film) formed from an organic compound such as a polymer), an oblique deposition film from an inorganic compound, a film having microgrooves, and a film formed by accumulating a Langmuir-Blodgett film (LB film) formed with an organic compound (for example, ω-trichosanic acid, dioctadecylmethylammonium chloride, and a methyl stearate) by a Langmuir-Blodgett method. 
     From the viewpoint of preventing alignment defects caused by foreign matters, a photoalignment layer formed from a photoalignment film is also preferable as the alignment layer. 
     Examples of the rubbing alignment film include coating films of a polyimide, a polyvinyl alcohol, the polymer having a polymerizable group described in JP1997-152509A (JP-H09-152509A), and the like, and the alignment films described in JP2005-97377A, JP2005-99228A, and JP2005-128503A.

For example, the materials using azo compounds described in WO08/056597A, JP2008-76839A, and JP2009-109831A; the photoalignment polyorganosiloxane composite materials described in JP2012-155308A, JP2014-26261A, JP2014-123091A, and JP2015-26050A; the cinnamic acid group-containing cellulose ester materials described in JP2012-234146A; the materials using an optical Fries rearrangement reaction or its analogous reaction described in JP2012-145660A and JP2013-238717A; the photodimerizable compounds (for example, materials in which a cinnamate compound, a chalcone compound, and/or a coumarin compound are pendant on various polymers) described in JP2016-71286A, JP2013-518296A, JP2014-533376A, JP2016-535158A, WO10/150748A, WO11/126022A, WO13/054784A, WO14/104320A, and WO16/002722A; or the like can be used in the composition for forming a photoalignment film. 
     Among those, from the viewpoint of irradiation energy, alignment regulating force, and the like required for photoalignment, a photoalignment film using the photoisomerization reaction of an azo group or a photoalignment film using the photoreaction of a cinnamate compound is preferable. 
     A crosslinking agent, a binder, a plasticizer, a sensitizer, a crosslinking catalyst, an adhesion modifier, a leveling agent, or the like may be added to a composition for forming an alignment film (preferably a composition for forming a photoalignment film) used for formation of an alignment film, as desired. 
     The film thickness of the alignment layer is not particularly limited, can be appropriately selected depending on purposes, and is, for example, preferably 10 to 1,000 nm, and more preferably 10 to 300 nm. The surface roughness of the alignment layer is the same as described above. 
     Other Layers (Interlayer)

Examples of the layer include a smoothing layer, an easy adhesive layer, an easy peelable layer, a light-blocking layer, a colored layer, a fluorescent layer, an oxygen barrier layer, and a water vapor barrier layer. Layers having one or more of the functions of such layers are collectively referred to as an interlayer. The interlayer may be a layer having a function other than the functions as described above. 
     Various functions can be expressed by providing the interlayer, for example, between the support and the optically anisotropic layer and/or between the support and the above-mentioned alignment layer, or the like. 
     Method for Producing Liquid Crystal Film 
     The liquid crystal film of the embodiment of the present invention can be manufactured by, for example, sequentially laminating and applying compositions for forming the respective layers (a liquid crystal composition and the like) onto a support. 
     Preferred aspects of the method include an aspect including the following steps (1) to (4) in this order. 
     (1) A step of applying a composition for forming an alignment film onto a support to obtain a coating film (coating step)

     For the light irradiation treatment to which the coating film formed with the composition for forming a photoalignment film is subjected, it is preferable to perform irradiation with polarized light. The polarized light is not particularly limited, examples thereof include linearly polarized light, circularly polarized light, and elliptically polarized light, and among these, the linearly polarized light is preferable. From the viewpoint of forming a liquid crystal layer which is horizontally aligned, it is preferable to perform irradiation with polarized light from the vertical direction, and from the viewpoint of imparting tilt alignment or a tilt, it is preferable to perform irradiation with polarized light from the oblique direction. 
     The wavelength with regard to polarized light or non-polarized light is not particularly limited as long as it can impart a coating film formed with the composition for forming a photoalignment film with an alignment control ability on a polymerizable liquid crystal compound or the like. Examples of the light used include ultraviolet rays, near-ultraviolet rays, and visible light. Among those, near-ultraviolet rays at 250 to 450 nm are preferable. 
     In addition, examples of a light source for irradiation with polarized light or non-polarized light include a xenon lamp, a high-pressure mercury lamp, an ultra-high-pressure mercury lamp, a metal halide lamp, a laser, and a light emitting diode (LED). A wavelength range for irradiation can be limited by using an interference filter, a color filter, or the like with respect to ultraviolet rays or visible light obtained from the light source, as desired. In addition, linearly polarized light can be obtained by using a polarizing filter, a polarizing prism, or the like with respect to light from these light sources. 
     An integrated amount of the polarized light or non-polarized light is not particularly limited as long as it can impart the coating film from the composition for forming a photoalignment film with an alignment control ability on the polymerizable liquid crystal compound, and is, for example, preferably 1 to 300 mJ/cm 2 , and more preferably 3 to 100 mJ/cm 2 . 
     An illuminance of the polarized light or non-polarized light is not particularly limited as long as it can impart the coating film from the composition for forming a photoalignment film with an alignment control ability on the liquid crystal compound, and is, for example, preferably 0.1 to 300 mW/cm 2 , and more preferably 1 to 100 mW/cm 2 . 
     Hardcoat Film 
     The hardcoat film of an embodiment of the present invention is a hardcoat film having a layer formed from the above-mentioned composition of the embodiment of the present invention. 
     Suitable examples of the composition for forming such a hardcoat film include a composition having the above-mentioned fluorine-containing polymer of the embodiment of the present invention incorporated into a curable composition (for example, a curable composition containing a polyorganosylsesquioxane including the siloxane constitutional unit containing an epoxy group described in JP2017-008143A, JP2018-192704A, and the like). 
     In addition, such a hardcoat film can be produced, for example, by applying the above-mentioned composition on a cellulose ester substrate, followed by drying and then irradiating with ultraviolet rays to cure the coating layer. 
     Polarizing Plate 
     The polarizing plate of an embodiment of the present invention is a polarizing plate having a layer formed from the composition of the above-mentioned embodiment of the present invention. 
     Examples of the structure of the polarizing plate of the embodiment of the present invention include a polarizer and the hardcoat film of the embodiment of the present invention provided as a protective film on at least one surface of the polarizer. 
     In addition, in another configuration of the polarizing plate of the embodiment of the present invention, the polarizing plate may include a polarizer, the hardcoat film of the embodiment of the present invention provided as a protective film on one surface of the polarizer, and an optical compensation film having optical anisotropy provided on the other surface of the polarizer. The optical compensation film in this case can be the same as the above-mentioned optically anisotropic layer. 
     As described above, it is preferable that the polarizing plate of the embodiment of the present invention is composed of a polarizer and a protective film that protects both sides thereof, and it is more preferable that the protective film is bonded to one surface of the polarizing plate and a separate film is bonded on the opposite surface. 
     The protective film and the separate film are used for the purpose of protecting the polarizing plate at the time of shipping of the polarizing plate, product inspection, or the like. Incidentally, the protective film is bonded for the purpose of protecting the surface of the polarizing plate, and is used on the opposite surface side of a surface where the polarizing plate is bonded to a liquid crystal plate. In addition, the separate film is used for the purpose of covering an adhesive layer to be bonded to the liquid crystal plate, and is used on a surface side where the polarizing plate is bonded to the liquid crystal plate. 
     The method for manufacturing a polarizing plate of the embodiment of the present invention is not particularly limited, and the polarizing plate can be manufactured by a general method. 
     For example, a method in which the obtained hardcoat film is subjected to an alkali treatment and is adhered to both sides of a polarizer manufactured by immersing a polyvinyl alcohol film in an iodine solution and stretching the film, using a completely saponified aqueous polyvinyl alcohol solution. In addition, instead of the alkali treatment, the easy-adhesion processing as described in JP1994-94915A (JP-H06-94915A) and JP1994-118232A (JP-H06-118232A) may be carried out. Moreover, the surface treatment as mentioned above may be performed. The surface on which the hardcoat film is bonded to the polarizer may be a surface on which the hardcoat layer is laminated or a surface on which the hardcoat layer is not laminated. 
     Examples of the adhesive used for adhering the protective film-treated surface to the polarizer include a polyvinyl alcohol-based adhesive such as a polyvinyl alcohol and a polyvinyl butyral, and a vinyl-based latex such as butyl acrylate.

     Manufacture of Cellulose Acylate Film 1 
     The core layer cellulose acylate dope and the outer layer cellulose acylate dope were filtered through a filter paper having an average pore diameter of 34 μm and a sintered metal filter having an average pore diameter of 10 μm and then all the three layers of the core layer cellulose acylate dope and the outer layer cellulose acylate dopes of both sides thereof were simultaneously cast on a drum at 20° C. from a casting port (band casting machine). Peeling was performed in the state where the solvent content was approximately 20% by mass, and the both ends of the film in the width direction were fixed with a tenter clip and dried while stretching the film at a stretching ratio of 1.1 times in the transverse direction. Thereafter, the obtained film was transported between rolls of a heat treatment device and further dried to manufacture an optical film having a thickness of 40 μm which was taken as a cellulose acylate film 1. In the obtained cellulose acylate film 1, the thickness of the core layer was 36 μm and the thickness of each of the outer layers arranged on the both sides of the core layer was 2 μm. The in-plane retardation of the obtained cellulose acylate film 1 at a wavelength of 550 nm was 0 nm. 
     The obtained cellulose acylate film 1 was taken as a support. 
     Manufacture of Liquid Crystal Film 
     The composition for forming a photoalignment film prepared above was applied onto a surface of one side of the manufactured cellulose acylate film 1 with a bar coater. 
     After applying the composition for forming a photoalignment film, the obtained film was dried for 1 minute on a hot plate at 120° C. to remove the solvent, thereby forming a composition layer for forming a photoalignment film having a thickness of 0.3 μm. 
     The obtained composition layer for forming a photoalignment film was irradiated with polarized ultraviolet rays (10 mJ/cm 2 , an ultra-high pressure mercury lamp was used) to form a photoalignment layer. 
     Subsequently, the liquid crystal compositions prepared above (Examples 1 to 25 and Comparative Examples 1 to 4) were each applied onto the photoalignment layer with a bar coater, thereby forming a liquid crystal composition layer. 
     The formed liquid crystal composition layer was once heated to 110° C. on a hot plate and then cooled to 60° C. to stabilize the alignment. 
     Thereafter, the liquid crystal composition layer was kept at 60° C. and irradiated with ultraviolet rays (500 mJ/cm 2 , an ultra-high pressure mercury lamp was used) in a nitrogen atmosphere (an oxygen concentration of 100 ppm) to fix the alignment, thereby forming an optically anisotropic layer having a thickness of 2.3 μm, from which a liquid crystal film was manufactured. The in-plane retardation of the obtained liquid crystal film at a wavelength of 550 nm was 140 nm. 
     Evaluation of Aligning Properties 
     The manufactured liquid crystal film was observed in the state of being 2° shifted from an extinction position with a polarizing microscope. A state where a partial difference in brightness upon observation did not exist was evaluated as a case where the liquid crystal director is uniformly aligned (excellent aligning properties). 
     The results of observation were classified in light of the following standard. The results are shown in Table 5 below. 
     AA: The liquid crystal director is finely arranged and aligned, and the display performance is very excellent. 
     A: The liquid crystal director is uniformly arranged and aligned, and the display performance is excellent. 
     B: Disturbance of the liquid crystal director is partial and the surface state is stable. 
     C: The liquid crystal director is significantly disturbed, the surface state is not stable, and thus, the display performance is extremely deteriorated. 
     Evaluation of Interference Unevenness in Liquid Crystal Composition Layer 
     In order to prevent reflection on a surface (back surface) of the liquid crystal film opposite to the liquid crystal composition layer, the back surface was painted with a black marker, and then the front surface (the surface on which the liquid crystal composition layer was applied) of the liquid crystal film was observed under a 3-wavelength fluorescent lamp with a diffuser mounted on the front surface. The liquid crystal film was visually observed from the front surface and evaluated according to the following evaluation standard. 
     A: There were no interference fringes. 
     B: Very few interference fringes were seen, but they were not noticeable. 
     C: Interference fringes were seen in some places, but were acceptable for a product. 
     D: Interference fringes were strongly generated, and are problematic. 
     Evaluation of Bumpy Defects in Liquid Crystal Composition Layer 
     Irradiation with a fluorescent lamp was performed from the back surface side, and 3 m 2  inspection was performed by a transmission visual inspection from the liquid crystal composition layer coating surface (front surface) side and a reflection visual inspection irradiated with the fluorescent lamp from the liquid crystal composition layer coating surface side, and bright spot-like defects were collected. Furthermore, the collected defects were analyzed with a microscope, IR, and a microscopic Raman spectroscope, the number of defects whose composition is the same as that of the normal part was counted, and the value was divided by 3 to calculate the number of bumpy defects per m 2 . 
     A: The number of bumpy defects is 0 in terms of 1 m 2 , and no defects are generated. 
     B: One to five bumpy defects were generated in terms of 1 m 2 , which is, however, infrequent and is not problematic. 
     C: Six or more bumpy defects were generated in terms of conversion to 1 m 2 , which is problematic. 
     Evaluation of Cissing 
     A liquid crystal film for evaluation of cissing was manufactured in the same manner as in the production of the above-mentioned production of the liquid crystal film, except that the liquid crystal composition layer obtained using the following liquid crystal composition was used instead of the liquid crystal composition layer used in the above-mentioned evaluations (aligning properties, interference unevenness, and bumpy defects).

     The number of cissings in the liquid crystal composition layer in each of the manufactured liquid crystal films was counted. Furthermore, a region on the surface of the photoalignment layer, where the liquid crystal composition layer was not formed, was designated as a cissing. Based on the results, evaluation was performed according to the following standard. The evaluation standard A or B indicates that the production efficiency is excellent and the product can be suitably used, and thus, the evaluation standard A is more preferable. 
     A: There are 1 or less cissings 
     B: There are 1 to 3 cissings 
     C: There are 4 to 9 cissings 
     D: There are 10 or more cissings 
     The results above are shown in Table 5 below. Furthermore, in Table 5 below, SURFLON S243 is a fluorine-containing material manufactured by AGC Seimi Chemical Co., Ltd., and MEGFACE F-444 and F-554 are both a fluorine-containing material manufactured by

     From the results shown in Table 5 above, it was confirmed that the liquid crystal film having the fluorine-containing polymer of the embodiment of the present invention is a film with high homogeneity, having excellent aligning properties, and less interference unevenness, bumpy defects, and cissing (Examples 1 to 25). 
     From the comparison of Examples 1 to 25, it was shown that the liquid crystal film formed using the fluorine-containing polymer having a repeating unit derived from the liquid crystal compound can further suppress cissing (Examples 22 to 25).
