Abstract
Description
Polymerizable liquid crystal compounds and methods for producing the same, polymerizable compositions, polymers, phase difference films and methods for producing the same, transfer laminates, optical components and methods for producing the same, and display devices.
[0001] This disclosure relates to polymerizable liquid crystal compounds, intermediates thereof, methods for producing the same, polymerizable compositions, polymers, phase difference films and methods for producing the same, transfer laminates, optical components and methods for producing the same, and display devices.
[0002] Conventionally, configurations have been proposed for display devices such as liquid crystal displays and light-emitting displays in which optical components such as phase difference films and polarizing plates are arranged on the panel surface. For example, in light-emitting displays such as organic light-emitting displays, highly reflective metal electrodes are provided in order to efficiently utilize the light from the light-emitting layer. On the other hand, the use of such metal electrodes increases ambient light reflection. Therefore, in light-emitting displays, it is known that a circular polarizer consisting of a quarter-wave plate that converts linearly polarized light to circularly polarized light and a polarizer is used on the viewing side in order to suppress such ambient light reflection.
[0003] Phase difference films include not only the quarter-wave plates mentioned above, but also half-wave plates that change the polarization plane of linearly polarized light by 90 degrees. These phase difference films can accurately convert a certain type of monochromatic light into a phase difference of 1 / 4λ or 1 / 2λ of the light wavelength. However, conventional phase difference films have the problem that the polarization output after passing through the phase difference film is converted into colored polarization. This is because the material constituting the phase difference film has wavelength dispersion with respect to the phase difference, resulting in a distribution of polarization states for each wavelength in white light, which contains light rays in the visible light range. To prevent this problem, it is necessary to control the wavelength dispersion so that the designed phase difference is achieved at each wavelength, and there is a need for a broadband phase difference film that can provide a uniform phase difference over a wide wavelength range of light, so-called phase difference film with inverse wavelength dispersion.
[0004] Furthermore, with the increasing functionality and widespread use of portable information terminals, there is a growing demand for thinner display devices, and consequently, for thinner phase difference films, which are a component of these devices. Therefore, development has been underway to create a phase difference layer with inverse wavelength dispersion in a single layer, by reducing or reversing the wavelength dispersion of the birefringence (Δn) (for example, Patent Documents 1-3). Note that the wavelength λ of the incident light on the phase difference film is plotted on the horizontal axis, and its birefringence (Δn = refractive index n for extraordinary light) is also being considered. e - Refractive index n relative to ordinary light 0 It is generally said that if the slope of the graph obtained by plotting the birefringence on the vertical axis is positive (sloping upwards), then the wavelength dispersion of that birefringence is inverse, or the liquid crystal compound of the material constituting the phase difference film has inverse wavelength dispersion.

[0006] However, polymerizable liquid crystal compounds exhibiting inverse wavelength dispersion or flat wavelength dispersion, as disclosed in Patent Documents 1 to 3, etc., have insufficient solvent solubility, making it difficult to create inks suitable for film manufacturing such as phase difference layers, or making it difficult to create films that satisfy the required physical properties due to crystal precipitation during film manufacturing such as phase difference layers. Insufficient solvent solubility of polymerizable liquid crystal compounds limits the solvents that can be used, making it impossible to use solvents suitable for the manufacturing process, resulting in solvent residue in films such as phase difference layers and increasing the environmental burden. In view of the above-mentioned circumstances, the embodiments of this disclosure aim to provide a polymerizable liquid crystal compound having good solvent solubility and capable of forming a phase difference layer exhibiting inverse wavelength dispersion or flat wavelength dispersion, an intermediate for the polymerizable liquid crystal compound, a method for producing the polymerizable liquid crystal compound, a polymerizable composition containing the polymerizable liquid crystal compound, a polymer obtained by polymerizing the polymerizable liquid crystal compound or the polymerizable composition, a phase difference film having a phase difference layer containing a cured product of the polymerizable composition and a method for producing the same, a transfer laminate capable of transferring the phase difference layer, an optical member having the phase difference film and a method for producing the same, and a display device.

[0099] Compounds represented by the general formula (Ar-im) can be produced, for example, from amine compounds via hydrazine compounds, as described in Chemical Communications (Cambridge, United Kingdom) (2016), 52(56), 8733-8736. Depending on the reaction conditions, T 1 or T 2 The reaction may be carried out after protecting the compound with a protecting group.
[0100] (In the formula, Ar, T 1 , and T 2 The signs are equivalent to each sign in the general formula (Ar-im), and R x and R y (These symbols are equivalent to the symbols in general formula (J-1).)
[0101] The starting material, an amine compound, can also be produced, for example, by reducing a nitro compound, and in this case T 1 or T 2The amino group may be protected with a protecting group before the reaction. A general reducing agent can be used for reduction. The starting amine compound can be prepared by referring to, for example, Journal of the American Chemical Society (2009), 131(31), 11049-11061 or Bioorganic & Medicinal Chemistry Letters (2012), 22(24), 7451-7455 regarding the introduction of the amino group. Alternatively, commercially available compounds may be appropriately selected and used as the starting amine compound.
[0102] For example, L 1 and L 2 A polymerizable liquid crystal compound represented by the following general formula (I-1), where each of the elements is *-OCO- (where * indicates the bonding position with Ar), can be produced by preparing a compound represented by the following general formula (Ar-im1), a compound represented by the general formula (mc-1), and a compound represented by the general formula (mc-2), and then simultaneously or sequentially carrying out a condensation reaction of the compound represented by the following general formula (Ar-im1), the compound represented by the general formula (mc-1), and the compound represented by the general formula (mc-2).
[0103] (In general formulas (Ar-im1), (mc-1), (mc-2), and (I-1), Ar-(J 1 ) k This represents a divalent group represented by any of the general formulas (Ar-1) to (Ar-7), and is synonymous with each sign of the divalent group represented by any of the general formulas (Ar-1) to (Ar-7), A 1 A 2 A 3 A 4 , L 3 , L 4 , R 1 and R 2 Furthermore, m1 and m2 are each independently synonymous with the respective symbols in the general formula (I).
[0104] The compound represented by the general formula (Ar-im1) is, in the compound represented by the general formula (Ar-im), T 1 and T2 The same synthesis can be performed if the group is -OH.
[0105] Next, we have the compound represented by the general formula (Ar-im1) and the general formula (mc-1): HOOC-A 1 - (L 3 -A 3 ) m1 -R 1 Compound represented by (A 1 , L 3 A 3 , R 1 , and m1 have the same meaning as above), and general formula (mc-2): HOOC-A 2 - (L 4 -A 4 ) m2 -R 2 Compound represented by (A 2 , L 4 A 4 , R 2 By simultaneously or sequentially condensing the compounds represented by the following general formula (I-1), the compounds represented by the following general formula (mc-1) can be produced. The order in which the compounds represented by general formula (mc-1) and general formula (mc-2) are sequentially condensed is arbitrary. An intermediate may be obtained by condensing the compound represented by general formula (mc-1) with the compound represented by general formula (Ar-im1), and then the compound represented by general formula (mc-2) may be further condensed with the intermediate. Alternatively, an intermediate may be obtained by condensing the compound represented by general formula (mc-2) with the compound represented by general formula (Ar-im1), and then the compound represented by general formula (mc-1) may be further condensed with the intermediate. If the structures of the compound represented by general formula (mc-1) and the compound represented by general formula (mc-2) are the same, then the compounds represented by general formula (mc-1) and general formula (mc-2) can be condensed simultaneously. In essence, the compound represented by general formula (I-1) can be produced by condensing the compound represented by general formula (Ar-im1) with the compound represented by general formula (mc-1) at a 2:1 molar equivalent ratio.
[0106]
[0107] Furthermore, the polymerizable liquid crystal compound represented by general formula (I) of this disclosure may not use the compound represented by general formula (Ar-im) and the substituent E may be introduced later, depending on the type and substitution position of substituent E. Also, the polymerizable liquid crystal compound represented by general formula (I) of this disclosure may not use the compound represented by general formula (Ar-im) and the substituent E may be introduced later. 1 This can also be obtained by introducing [a certain method].
[0108] Furthermore, each intermediate used in the manufacturing process may be a commercially available product as appropriate, or it may be synthesized as appropriate by conventionally known methods.
[0109] In this disclosure, the structure of polymerizable liquid crystal compounds can be analyzed by appropriately combining nuclear magnetic resonance spectroscopy (NMR), pyrolysis gas chromatography-mass spectrometry (Py-GC-MS), and matrix-assisted laser desorption / ionization time-of-flight mass spectrometry (MALDI-TOFMS).
[0110] Furthermore, the polymerizable liquid crystal compounds of this disclosure are polymerizable liquid crystal compounds capable of forming a phase difference layer exhibiting inverse wavelength dispersion or flat wavelength dispersion. When a polymerizable composition containing only the polymerizable liquid crystal compounds of this disclosure and a photopolymerization initiator is prepared, a cured film (phase difference layer) is formed, and the phase difference value is measured, it is preferable that Re(450) / Re(550) is in the range of 0.60 or more and less than 1.05, more preferably in the range of 0.60 or more and less than 1.00, even more preferably in the range of 0.60 or more and less than 0.95, and even more preferably in the range of 0.60 or more and less than 0.93. In addition, it is preferable that Re(650) / Re(550) is greater than 1.00, and even more preferably in the range of 1.02 or more and 1.10 or less. The following measurement methods can be used as test methods for the phase difference value. [Test Method] A polymerizable composition is prepared by dissolving 100 parts by mass of the polymerizable liquid crystal compound of this disclosure and 4 parts by mass of 2-methyl-1-(4-methylthiophenyl)-2-morpholinopropan-1-one in 900 parts by mass of cyclopentanone. This polymerizable composition is then rubbed onto glass with a polyimide alignment film [the alignment-treated glass substrate is coated with polyimide LX-1400 manufactured by Hitachi Chemical Co., Ltd. and then rubbed]. Polyimide LX-1400 is spin-coated onto the glass substrate, and the unspin-coated glass surface is placed on a hot plate at 80°C for 1 minute to dry and produce a polyimide coating on the glass substrate. The polyimide-coated glass substrate is baked in an oven at 230°C for 30 minutes. The polyimide coating on the polyimide-coated glass substrate is rubbed to obtain glass with a polyimide alignment film after rubbing. The rubbing conditions are as follows. The film was formed by coating an alignment film with a roll rotation speed of 600 rpm, a travel speed of 30 mm / sec, and 3 reciprocations, so that the cured film thickness would be 1 μm. After drying for 120 seconds at a temperature 10°C above the solid-liquid crystal phase transition temperature (°C) of the polymerizable liquid crystal compound contained, the film was irradiated with ultraviolet light at a dose of 400 mJ / cm². 2A phase difference layer is formed by irradiation, and the in-plane phase difference Re(450) for a wavelength of 450 nm and the in-plane phase difference Re(550) for a wavelength of 550 nm are measured using a phase difference measuring device (KOBRA series, manufactured by Oji Instruments Co., Ltd.). (A1) First, in order to stabilize the light source of the phase difference measuring device, leave it for more than 60 minutes after turning on the light source. Then, select waveplate measurement and obtain data from the reference analyzer. (A2) Use the wavelength dispersion characteristic mode and set the measurement conditions as follows and perform the measurement. (Measurement conditions) ・Measurement mode: Standard ・Tilt central angle: Leading axis ・Incident angle: 0° ・Average number of measurements: 3 times ・Average refractive index of the layer to be measured: The measured value (average refractive index) of the orientation measurement sample was entered using an Abbe refractometer (manufactured by Atago) with sodium D line (589 nm) as the light source, in accordance with JIS K7142:2014. ・Thickness: Enter the total thickness of the horizontal alignment layer and the phase difference layer. Furthermore, similar results can be obtained by forming a phase difference layer using the method shown in Example 1 described later and measuring the phase difference value.
[0111] Furthermore, the polymerizable liquid crystal compounds of this disclosure preferably have a solid-liquid crystal phase transition temperature of 25°C to 200°C, more preferably 30°C to 180°C, and even more preferably 30°C to 150°C, as this expands the range of usable substrates. A lower solid-liquid crystal phase transition temperature reduces the load in the liquid crystal orientation process and allows use on substrates that are sensitive to high temperatures. Here, the solid-liquid crystal phase transition temperature refers to the temperature at which the liquid crystal compound changes from a solid to a liquid crystal. In this disclosure, the solid-liquid crystal phase transition temperature is confirmed during heating by texture observation using a polarizing microscope equipped with a temperature control stage. That is, in polarizing microscope observation, the point at which the solid melts and becomes liquid during heating, and which becomes bright-field in crossed nicol observation (polarizing plates are orthogonal), can be identified as the solid-liquid crystal phase transition temperature.
[0112] Furthermore, the polymerizable liquid crystal compound of this disclosure is preferably solvable in 10% by mass or more in at least one solvent selected from the group consisting of methyl ethyl ketone, methyl isobutyl ketone, cyclopentanone, and cyclohexanone, in order to broaden the range of usable substrates, more preferably solvable in 20% by mass or more, and even more preferably solvable in 30% by mass or more.
[0113] B. Polymerizable Compositions The polymerizable compositions of this disclosure are compositions comprising at least the polymerizable liquid crystal compound of this disclosure.
[0114] Since the polymerizable composition of this disclosure contains the polymerizable liquid crystal compound of this disclosure, as described above, it can be a polymerizable composition that has good solvent solubility and can form a phase difference layer exhibiting inverse wavelength dispersion and flat wavelength dispersion. Since the polymerizable composition of this disclosure contains the polymerizable liquid crystal compound of this disclosure, it is easy to prepare a composition (ink) containing a solvent suitable for film manufacturing such as a phase difference layer, crystal precipitation is less likely to occur during film manufacturing such as a phase difference layer, and it is possible to create a film that satisfies the required physical properties. Because the polymerizable liquid crystal compound has good solvent solubility, a solvent suitable for the manufacturing process can be used as the solvent that can be used in the polymerizable composition.
[0115] The polymerizable composition of this disclosure contains at least the polymerizable liquid crystal compound of this disclosure, but more preferably contains a photopolymerization initiator. Furthermore, the polymerizable composition of this disclosure may contain polymerizable liquid crystal compounds different from the polymerizable liquid crystal compound of this disclosure, in order to adjust the phase difference and wavelength dispersibility, as well as the orientation, solubility, and phase transition temperature, and may also contain other components to the extent that the effects are not impaired. The components constituting the polymerizable composition of this disclosure will be described in order below.

[0132]
[0133] Suitable specific examples of compounds represented by general formula (III) and general formula (IV) include, but are not limited to, those shown in the following chemical formulas (1) to (22).
[0134] (g is an integer between 2 and 5.)
[0135]
[0136] As polymerizable liquid crystal compounds different from those of the present disclosure, they should be appropriately selected so that when the phase difference value is measured, Re(450) / Re(550) is within the range of 0.60 or more and less than 1.05. As polymerizable liquid crystal compounds different from those of the present disclosure, Re(450) / Re(550) can be selected from those of 0.60 or more and less than 1.20, but it is preferable to select from those of 0.80 or more and less than 1.20, and even more preferable to select from those of 0.90 or more and less than 1.20. The phase difference value here is measured in the same manner as the phase difference value test method described above.
[0137] Furthermore, in this embodiment, it is preferable that a polymerizable liquid crystal compound different from the polymerizable liquid crystal compound of this disclosure be dissolved in at least 20% by mass or more of at least one solvent selected from the group consisting of methyl ethyl ketone, methyl isobutyl ketone, cyclopentanone, and cyclohexanone, in order to improve the solvent solubility of the polymerizable composition. Improved solvent solubility of the polymerizable composition is preferable because it facilitates the formation of a uniform coating film when forming a coating film using the polymerizable composition, reduces the load on the manufacturing process and equipment for drying the solvent, expands the range of usable substrates, and broadens the liquid crystal phase transition temperature of the composition, widening the process margin during orientation and resulting in more uniform and better orientation.
[0138] In this embodiment, polymerizable liquid crystal compounds different from the polymerizable liquid crystal compounds of this disclosure can be used individually or in combination of two or more. In this embodiment, the content ratio of polymerizable liquid crystal compounds different from the polymerizable liquid crystal compounds of this disclosure is not limited and can be adjusted as appropriate to adjust the desired phase difference, etc., but is preferably 7 parts by mass or more and 49.9 parts by mass or less, more preferably 10 parts by mass or more and 45 parts by mass or less, and even more preferably 10 parts by mass or more and 42 parts by mass or less, per 100 parts by mass of solid content of the polymerizable composition. Furthermore, the content ratio of polymerizable liquid crystal compounds different from the polymerizable liquid crystal compounds of this disclosure can be adjusted as appropriate to adjust the desired phase difference, etc., but is preferably 50 parts by mass or less, more preferably 45 parts by mass or less, and may be 40 parts by mass or less, per 100 parts by mass of the total amount of polymerizable liquid crystal compounds of this disclosure and polymerizable liquid crystal compounds different from the polymerizable liquid crystal compounds of this disclosure.
[0139] 4. Other Components The polymerizable composition of this embodiment may contain other components as long as they do not impair the effect. Specifically, other components may include leveling agents, antioxidants, light stabilizers, and solvents from the viewpoint of coating properties. It may also contain polymerizable compounds that do not exhibit liquid crystalline properties on their own but can be used together with the polymerizable liquid crystal compound of this disclosure to adjust the phase difference, inverse wavelength dispersion, phase transition temperature, hardness, and durability. These can be appropriately selected from conventionally known materials.
[0140] To improve the hardness and durability of the coating film, it is preferable to further include a polymerizable compound having two or more polymerizable functional groups in one molecule. In addition to the polymerizable liquid crystal compounds mentioned above, polymerizable compounds that do not have liquid crystal properties can also be used as polymerizable compounds having two or more polymerizable functional groups in one molecule. Polymerizable compounds having two or more polymerizable functional groups in one molecule can also be so-called polyfunctional monomers, for example, trimethylolpropane tri(meth)acrylate, tripropylene glycol di(meth)acrylate, diethylene glycol di(meth)acrylate, dipropylene glycol di(meth)acrylate, pentaerythritol tri(meth)acrylate, pentaerythritol tetra(meth)acrylate, dipentaerythritol hexa(meth)acrylate, 1,6-hexanediol di(meth)acrylate, neopentyl glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, ditrimethylolpropane tetra(meth)acrylate, dipentaerythritol hexa(meth)acrylate, dipentyl glycol di(meth)acrylate, dimethylolpropane tri(meth)acrylate, dipentylpropane tetra(meth)acrylate, dipentylpropane Examples include pentaerythritol penta(meth)acrylate, tripentaerythritol octa(meth)acrylate, tetrapentaerythritol deca(meth)acrylate, isocyanuric acid tri(meth)acrylate, isocyanuric acid di(meth)acrylate, polyester tri(meth)acrylate, polyester di(meth)acrylate, bisphenol di(meth)acrylate, diglycerin tetra(meth)acrylate, adamantyl di(meth)acrylate, isoboronyl di(meth)acrylate, dicyclopentane di(meth)acrylate, tricyclodecane di(meth)acrylate, ditrimethylolpropane tetra(meth)acrylate, and modified versions of these with PO, EO, etc. Polymerizable compounds having three or more polymerizable functional groups in one molecule, such as pentaerythritol triacrylate (PETA), dipentaerythritol hexaacrylate (DPHA), pentaerythritol tetraacrylate (PETTA), dipentaerythritol pentaacrylate (DPPA), and trimethylolpropane triacrylate (TMPTA), are preferred because the crosslinking reaction proceeds and the durability of the coating film is improved.In this embodiment, when a polymerizable compound that does not have liquid crystalline properties is used, its content is preferably 40 parts by mass or less, more preferably 30 parts by mass or less, and even more preferably 20 parts by mass or less, per 100 parts by mass of solids of the polymerizable composition. In this embodiment, as a polymerizable compound different from the polymerizable liquid crystalline compound of this disclosure, it is preferable to dissolve it in at least 20% by mass or more in at least one solvent selected from the group consisting of methyl ethyl ketone, methyl isobutyl ketone, cyclopentanone, and cyclohexanone. This is because it improves the solvent solubility of the polymerizable composition, makes it easier to form a uniform coating film when forming a coating film using the polymerizable composition, reduces the load on the manufacturing process and manufacturing equipment for drying the solvent, and expands the range of usable substrates.
[0141] As a leveling agent, it is preferable to use a fluorine-based or silicone-based leveling agent. Specific examples of leveling agents include, for example, the Megafac series manufactured by DIC Corporation, described in Japanese Patent Application Publication No. 2010-122325, the TSF series manufactured by Momentive Performance Materials Japan, and the Futergent series manufactured by Neos Corporation. In this embodiment, when a leveling agent is used, its content is preferably 0.001 parts by mass or more and 5 parts by mass or less per 100 parts by mass of solid content of the polymerizable composition.
[0142] The polymerizable composition of this embodiment may contain a solvent as needed, from the viewpoint of coating properties. The solvent can be appropriately selected from conventionally known solvents that can dissolve or disperse each component contained in the polymerizable composition. Specifically, examples include hydrocarbon solvents such as hexane, cyclohexane, and toluene; ketone solvents such as methyl ethyl ketone, methyl isobutyl ketone, cyclopentanone, and cyclohexanone; ether solvents such as tetrahydrofuran, 1,3-dioxolane, and propylene glycol monoethyl ether (PGME); alkyl halogenated solvents such as chloroform and dichloromethane; ester solvents such as ethyl acetate and propylene glycol monomethyl ether acetate; amide solvents such as N,N-dimethylformamide and N-methylpyrrolidone; sulfoxide solvents such as dimethyl sulfoxide; and alcohol solvents such as methanol, ethanol, and propanol. In this embodiment, the solvent can be used alone or in combination of two or more to form a mixed solvent.
[0143] The polymerizable composition of this embodiment is suitable for various applications due to its good orientation properties. As a liquid crystal composition, the polymerizable composition of this embodiment is suitable for applications such as phase difference films and various optical components, as described later.
[0144] C. Polymers The polymers of the present disclosure are obtained by polymerizing the polymerizable liquid crystal compound or polymerizable composition of the present disclosure. The polymerization method can be appropriately selected according to the polymerizable functional groups contained in the polymerizable liquid crystal compound of the present disclosure. Polymers obtained by polymerizing the polymerizable liquid crystal compound or polymerizable composition of the present disclosure without orientation can be used, for example, as light scattering plates, depolarizing plates, and moiré fringe prevention plates. Polymers obtained by polymerizing the polymerizable liquid crystal compound or polymerizable composition of the present disclosure after orientation have optical anisotropy and are suitably used in phase difference films and various optical component applications described later.
[0145] D. Phase Difference Film The phase difference film of this disclosure is a phase difference film having a phase difference layer, wherein the phase difference layer is made of a cured product of the polymerizable composition of this disclosure. In the above embodiment, since the phase difference layer of the phase difference film is made of a cured product of the polymerizable composition, it has a phase difference layer that exhibits inverse wavelength dispersion and flat wavelength dispersion. Because the polymerizable liquid crystal compound of this disclosure contained in the polymerizable composition has good solvent solubility, it is easy to prepare a polymerizable composition (ink) containing a solvent suitable for the production of the phase difference layer, so that crystal precipitation is less likely to occur during the production of the phase difference layer, and it is possible to form a phase difference layer that satisfies the required physical properties. Because the polymerizable liquid crystal compound has good solvent solubility, a solvent suitable for the manufacturing process can be used, so that solvent is less likely to remain in the phase difference layer, and the stability of the phase difference layer is also increased.
[0146] The layer structure of the phase difference film will be explained with reference to the figures. Figures 1 to 3 each show one embodiment of the phase difference film of the present disclosure. One embodiment of the phase difference film 10 shown in the example of Figure 1 is a phase difference film in which an alignment film 3 and a phase difference layer 1 are laminated in that order on a substrate 2. One embodiment of the phase difference film 10 shown in the example of Figure 2 is a phase difference film consisting only of a phase difference layer 1. Another embodiment of the phase difference film 10 shown in the example of Figure 3 has the phase difference layer 1 directly formed on the substrate 2'. The phase difference film shown in the example of Figure 3 may be provided with means for exerting an orientation restricting force on the surface of the substrate 2' on the side of the phase difference layer 1. Here, in the present disclosure, orientation restricting force refers to the effect of aligning the oriented components in the phase difference layer in a specific direction.
[0147] 1. Phase Difference Layer The phase difference layer 1 of the embodiment of this disclosure consists of a cured product of the polymerizable composition of this disclosure containing the polymerizable liquid crystal compound of this disclosure. Here, the polymerizable liquid crystal compound and the polymerizable composition of this disclosure may be the same as those described in the embodiment of this disclosure, so their description is omitted here.
[0148] Preferably, the phase difference layer is cured in a state in which the oriented main chain portion of the polymerizable liquid crystal compound of the present disclosure, and any further polymerizable liquid crystal compounds, are substantially horizontally oriented with respect to the film surface. The cured product of the polymerizable composition of the embodiment of the present disclosure includes a structure in which at least a portion of the polymerizable functional groups of the polymerizable compound are polymerized. Because such a structure in which at least a portion of the polymerizable functional groups of the polymerizable compound is included, the phase difference layer of this embodiment is a phase difference layer with improved durability.
[0149] Phase difference can be measured using a phase difference measuring device (KOBRA series, manufactured by Oji Instruments Co., Ltd.). By irradiating the phase difference layer surface perpendicularly or obliquely with the measurement light, the anisotropy that increases or decreases the phase difference of the phase difference layer, as well as the degree of orientation in the vertical (thickness) direction of the liquid crystal, can be confirmed from the chart of the optical phase difference and the angle of incidence of the measurement light.
[0150] Furthermore, it can be confirmed that the phase difference layer contains a structure in which at least a portion of the polymerizable functional groups of the polymerizable liquid crystal compound contained in the polymerizable composition of the present disclosure, or any other polymerizable liquid crystal compounds that may be included, are polymerized by sampling and analyzing the material from the phase difference layer. NMR, IR, GC-MS, XPS, TOF-SIMS, and combinations thereof can be applied as analytical methods.
[0151] The phase difference layer may contain other components such as photopolymerization initiators, leveling agents, antioxidants, and photostabilizers. Components that may decompose completely when irradiated with light to react the polymerizable functional groups of the polymerizable liquid crystal compound, such as photopolymerization initiators, may not be included in the phase difference layer.
[0152] The thickness of the phase difference layer can be set appropriately depending on the application. For example, when the phase difference film of this disclosure is used to make a broadband quarter-wave plate, the film thickness of the resulting phase difference film should be adjusted so that the Re(550) of the resulting phase difference film is 113 nm to 163 nm, preferably 135 nm to 140 nm, and particularly preferably about 137.5 nm. When it is used to make a half-wave plate, the film thickness should be adjusted so that the Re(550) of the resulting optical film is 250 nm to 300 nm, preferably 273 nm to 277 nm, and particularly preferably about 275 nm.
[0153] Furthermore, the film thickness can be adjusted to obtain the desired phase difference by appropriately adjusting the amount of polymerizable composition applied and the concentration of the polymerizable liquid crystal compound. The phase difference value (retardation value, Re(λ)) of the resulting phase difference layer is determined by the following formula, so in order to obtain the desired Re(λ), the film thickness d should be adjusted. Re(λ) = d × Δn(λ) (In the formula, Re(λ) represents the phase difference value at a wavelength of λnm, d represents the film thickness, and Δn(λ) represents the birefringence at a wavelength of λnm.) The thickness of the phase difference layer may be 0.1 μm or more and 5 μm or less, or 0.5 μm or more and 3 μm or less.
[0154] The wavelength dispersion characteristics of the phase difference film of this disclosure can be arbitrarily determined by the content of the polymerizable liquid crystal compound of this disclosure and other polymerizable liquid crystal compounds that may be contained in the phase difference layer. Furthermore, in order to approach ideal wavelength dispersion, when a polymerizable composition containing only the polymerizable liquid crystal compound of this disclosure and a photopolymerization initiator is prepared by the method shown in Example 1 below and a cured film (phase difference layer) is formed, it is preferable that Re(450) / Re(550) is in the range of 0.60 or more and less than 1.05, more preferably in the range of 0.60 or more and less than 1.00, even more preferably in the range of 0.78 or more and less than 0.95, and even more preferably in the range of 0.80 or more and less than 0.93. Furthermore, it is preferable that Re(650) / Re(550) is greater than 1.00, and even more preferably in the range of 1.02 or more and 1.10 or less.
[0155] 2. Alignment Film In this specification, an alignment film refers to a layer for aligning the liquid crystalline components contained in the phase difference layer in a certain direction. As the alignment film used in the embodiments of this disclosure, it is preferable to use a horizontal alignment film because the polymerizable composition of the embodiments of this disclosure is easily aligned horizontally. The horizontal alignment film is a film that, when provided as a coating film, aligns the long axis of the mesogen of the liquid crystalline components contained in the phase difference layer substantially horizontally with respect to the horizontal alignment film surface (film surface). As the horizontal alignment film, conventionally known films can be appropriately selected and used. For example, an alignment film to which alignment restricting force has been imparted by a rubbing method, a photo-alignment method, a shaping method, etc., can be cited. Among these, a horizontal alignment film to which alignment restricting force has been imparted by a rubbing method, a photo-alignment method, or a shaping method is preferred.
[0156] When orientation-regulating force is imparted by the rubbing method, the horizontal orientation film uses a polymer that exhibits orientation-regulating force through rubbing. Examples of such polymers include polyvinyl alcohol, polyimide, polyamide, and their derivatives, with polyvinyl alcohol being preferred.
[0157] The method for forming the horizontally aligned film by the rubbing method can be appropriately selected from conventionally known methods. For example, after forming a coating film containing the polymer on the transparent substrate, the horizontally aligned film can be obtained by rubbing it using a known rubbing roller or the like.
[0158] When forming a horizontally aligned film by photo-alignment, a photo-aligning composition containing a photo-aligning material that exhibits orientation-regulating force upon irradiation with polarized light is used as the alignment film composition. The photo-aligning material may be a photo-dimerizable material or a photo-isomerizable material. Specifically, examples include polymers having cinnamate, coumarin, benzylidenephthalimidine, benzylideneacetophenone, diphenylacetylene, stilbazole, uracil, quinolinone, maleimide, or cinnamyridene acetate derivatives. Among these, polymers having at least one of cinnamate and coumarin, and their derivatives, are preferred. Specific examples of such photodimerizing materials include, for example, the compounds described in Japanese Patent Publication No. 9-118717, Japanese Patent Publication No. 10-506420, Japanese Patent Publication No. 2003-505561, WO2010 / 150748, and Japanese Patent Publication No. 2015-151548.
[0159] The method for forming a photo-aligned film by the photo-alignment method can be appropriately selected from conventionally known methods. For example, a photo-aligned film can be obtained by uniformly coating the photo-alignable composition onto the transparent substrate, irradiating it with polarized light, and then irradiating the entire surface of the coating with light.
[0160] Furthermore, when forming a horizontally aligned film by a molding method, the composition for the alignment film can be appropriately selected from those capable of molding the desired fine uneven shape. For example, a molding composition containing an ultraviolet-curable resin, a thermosetting resin, an electron beam-curable resin, etc., can be used. Among these, an ultraviolet-curable resin is preferred because it facilitates the formation of the alignment film. Specific examples of ultraviolet-curable resins include, for example, the polymerizable monomers and oligomers mentioned above, as well as urethane acrylate, epoxy acrylate, polyester acrylate, polyether acrylate, melamine acrylate, etc., which can be used individually or in combination of two or more.
[0161] The method for forming the horizontally aligned film by the molding method can be appropriately selected from conventionally known methods. For example, by uniformly applying the molding composition onto the transparent substrate, bringing the coating into contact with a mold having a desired fine uneven shape, applying pressure, and irradiating with ultraviolet light, an oriented film with the desired fine uneven shape can be obtained.
[0162] Furthermore, the horizontal alignment film may be one which has been patterned and in which parts having alignment properties are arranged in a pattern. Known horizontal alignment films can be used, and are not particularly limited, but examples include rubbing alignment films that have been patterned by mask rubbing, photoalignment films that have been patterned by mask exposure, and alignment films that have been patterned by printing or the like.
[0163] The thickness of the horizontal alignment film can be set as appropriate, as long as it can orient the polymerizable rod-shaped liquid crystal compound horizontally, and is not particularly limited, but is usually 1 nm or more, preferably 60 nm or more, and from the viewpoint of thin film formation, it is 15 μm or less, preferably 10 μm or less, more preferably 1 μm or less, and even more preferably 0.3 μm or less.
[0164] 3. Substrate In this embodiment, the substrate can be a glass substrate, a metal foil, a resin substrate, etc. Among these, the substrate is preferably transparent and can be appropriately selected from conventionally known transparent substrates. Examples of transparent substrates include glass substrates, acetylcellulose resins such as triacetylcellulose, polyester resins such as polyethylene terephthalate, polyethylene naphthalate, polybutylene terephthalate, and polylactic acid, olefin resins such as polypropylene, polyethylene, and polymethylpentene, acrylic resins, polyurethane resins, and transparent resin substrates formed using resins such as polyethersulfone, polycarbonate, polysulfone, polyether, polyetherketone, acronitrile, methacrylonitrile, cycloolefin polymer, and cycloolefin copolymer.
[0165] The transparent substrate described above preferably has a transmittance of 80% or more in the visible light region, and more preferably 90% or more. Here, the transmittance of the transparent substrate can be measured according to JIS K7361-1:1997 (Plastics - Test method for total light transmittance of transparent materials).
[0166] Furthermore, when forming a phase difference layer using a roll-to-roll method, the transparent substrate is preferably a flexible material that can be wound into a roll. Examples of such flexible materials include cellulose derivatives, norbornene polymers, cycloolefin polymers, polymethyl methacrylate, polyvinyl alcohol, polyimide, polyarylate, polyethylene terephthalate, polysulfone, polyethersulfone, amorphous polyolefin, modified acrylic polymer, polystyrene, epoxy resin, polycarbonate, and polyesters. In this embodiment, it is preferable to use cellulose derivatives or polyethylene terephthalate. Cellulose derivatives are particularly excellent in optical isotropy, and therefore can be made to have excellent optical properties. Polyethylene terephthalate is also preferred because it has high transparency and excellent mechanical properties.
[0167] The thickness of the substrate used in this embodiment is not particularly limited as long as it can provide the necessary self-supporting properties depending on the application of the phase difference film, but is usually in the range of 10 μm to 1000 μm. In particular, the thickness of the substrate is preferably in the range of 25 μm to 125 μm, and more preferably in the range of 30 μm to 100 μm. If the thickness is greater than the above range, for example, when a long phase difference film is formed and then cut to form a single-sheet phase difference film, the amount of processing waste may increase or the cutting blade may wear out more quickly.
[0168] The substrate used in this embodiment is not limited to a single layer configuration, but may have a configuration in which multiple layers are laminated. In the case of a configuration with multiple laminated layers, layers of the same composition may be laminated, or multiple layers of different compositions may be laminated. For example, if the alignment film used in this embodiment contains an ultraviolet-curable resin, a primer layer may be formed on the substrate to improve the adhesion between the transparent substrate and the ultraviolet-curable resin. This primer layer may have adhesion to both the substrate and the ultraviolet-curable resin, be transparent in visible light, and allow ultraviolet light to pass through. For example, vinyl chloride / vinyl acetate copolymers, urethane-based primers, etc., can be appropriately selected and used.
[0169] Furthermore, an anchor coat layer may be laminated on the substrate. The strength of the substrate can be improved by this anchor coat layer. As the anchor coat material, metal alkoxides, particularly metal silicon alkoxide sols, can be used. Metal alkoxides are usually used as alcohol-based solutions. Since the anchor coat layer needs to be a uniform and flexible film, the thickness of the anchor coat layer is preferably 0.04 μm to 2 μm, and more preferably 0.05 μm to 0.2 μm. When the substrate has an anchor coat layer, the adhesion between the substrate and the anchor coat layer may be improved by further laminating a binder layer between the substrate and the anchor coat layer, or by incorporating a material that strengthens adhesion to the substrate into the anchor coat layer. The binder material used to form the binder layer can be any material that can improve the adhesion between the substrate and the anchor coat layer without particular limitations. Examples of binder materials include silane coupling agents, titanium coupling agents, zirconium coupling agents, and the like.
[0170] 4. Method for Manufacturing a Phase Difference Film The method for manufacturing a phase difference film according to the embodiment of the present disclosure comprises the steps of forming a phase difference layer by: forming a film of the polymerizable composition according to the embodiment of the present disclosure (film formation step); oriented at least the polymerizable compound in the formed polymerizable composition (orientation step); and polymerizing at least the polymerizable compound after the orientation step (polymerization step). The polymerizable composition can be the same as that described in "B. Polymerizable Composition" above, so its description is omitted here.
[0171] (1) Film formation process of polymerizable composition A polymerizable composition is uniformly applied to a support to form a film. As described above, the film thickness is adjusted to give a desired phase difference by appropriately adjusting the amount of polymerizable composition applied and the concentration of the polymerizable liquid crystal compound. The support here may be the substrate, or it may be the alignment film of the substrate equipped with the alignment film.
[0172] The coating method can be any method that can accurately form a film of the desired thickness, and can be selected as appropriate. Examples include gravure coating, reverse coating, knife coating, dip coating, spray coating, air knife coating, spin coating, roll coating, printing, immersion and pull-up, curtain coating, die coating, casting, bar coating, extrusion coating, and E-type coating methods.
[0173] (2) Orientation step Next, the polymerizable liquid crystal compound in the polymerizable composition that has been filmed is at least oriented. The polymerizable liquid crystal compound in the polymerizable composition that has been filmed is heated to a temperature at which orientation is possible. This heat treatment allows the main chain portion having orientation properties of the polymerizable liquid crystal compound of the present disclosure and, if necessary, polymerizable liquid crystal compounds other than the polymerizable compound of the present disclosure that are further contained to be oriented and dried, and the oriented state can be fixed. The temperature at which orientation is possible varies depending on each substance in the polymerizable composition, so it is necessary to adjust it as appropriate. For example, it is preferable to perform the heating in the range of 60°C to 200°C, and more preferably in the range of 60°C to 100°C. Known heating and drying means can be appropriately selected and used as the heating means. The heating time can be appropriately selected, but for example, it is selected in the range of 10 seconds to 2 hours, preferably 20 seconds to 30 minutes.
[0174] (3) Polymerization step After the orientation step, at least the polymerizable compound is polymerized. In the orientation step, the polymerizable compound can be polymerized by, for example, light irradiation of the coating film fixed in a state in which the orientation of the polymerizable compound and any further polymerizable liquid crystal compounds is maintained, thereby obtaining a phase difference layer made of a cured product of the polymerizable composition. Ultraviolet irradiation is preferably used as the light irradiation. Ultraviolet irradiation can be performed using ultraviolet light emitted from light rays such as ultra-high pressure mercury lamps, high pressure mercury lamps, low pressure mercury lamps, carbon arcs, xenon arcs, and metal halide lamps. The irradiation amount of the energy source can be appropriately selected, for example, 10 mJ / cm as the integrated exposure amount at an ultraviolet wavelength of 365 nm. 2 More than 10000mJ / cm 2 The following range is preferable.
[0175] 5. Applications The phase difference film of this disclosure is suitably used, for example, as an anti-reflective quarter-wave plate, and is suitably used as an optical component for various display devices as described later.
[0176] E. Transfer Laminate The transfer laminate of the present disclosure comprises a phase difference layer and a support that removably supports the phase difference layer, wherein the phase difference layer is made of a cured product of the polymerizable composition of the present disclosure, and is a transfer laminate for transferring a phase difference layer.
[0177] The transfer laminate of this embodiment has excellent optical properties because the phase difference layer is made of a cured product of the polymerizable composition, thereby suppressing the precipitation of polymerizable compounds. The transfer laminate of this embodiment allows for the transfer of the phase difference layer of this disclosure, for example, a thin film without a substrate, to any other optical component. The transfer laminate of this embodiment provides, for example, a phase difference film 10 consisting only of the phase difference layer 1 shown in the example of Figure 2, or a phase difference film consisting of a laminate 26 in which an alignment film 23 and a phase difference layer 21 are laminated without a substrate, as shown in the example of Figure 5. In other words, an alignment film or the like may be laminated on the phase difference layer used for transfer of the transfer laminate, as long as the phase difference layer is at least peelable. The configuration of such a transfer laminate will be described below, but the polymerizable composition of the embodiment of this disclosure has been described above, so its description will be omitted here.
[0178] The layer structure of the transfer laminate will be described with reference to the figures. Figures 4 and 5 show one embodiment of the transfer laminate of the present disclosure, respectively. One embodiment of the transfer laminate 20 shown in the example of Figure 4 is a transfer laminate in which an alignment film 13 and a phase difference layer 11 are laminated in this order on a second substrate 12, serving as a support 15 that peels off the phase difference layer and a phase difference layer 16 for transfer. In the transfer laminate shown in the example of Figure 4, the peel strength between the second substrate 12 and the alignment film 13 is greater than the peel strength between the alignment film 13 and the phase difference layer 11, so that the phase difference layer 11 (16) can be peeled off at the interface 17 between the alignment film and the phase difference layer and transferred. One embodiment of the transfer laminate 30 shown in the example of Figure 5 is a transfer laminate in which an alignment film 23 and a phase difference layer 21 are laminated in this order on a second substrate 22, serving as a support 25 that peels off the phase difference layer and a phase difference layer 26 for transfer. In the transfer laminate shown in the example of Figure 5, the peel strength between the second substrate 22 and the alignment film 23 is lower than the peel strength between the alignment film 23 and the phase difference layer 21. As a result, the phase difference layer 26, which is the phase difference layer 21 and the alignment film 23, is peeled off at the interface 27 between the second substrate 22 and the alignment film 23, and the phase difference layer 26 that can be transferred is an example of a transfer laminate.
[0179] For example, whether the delamination strength between the second substrate and the orientation film is greater or less than the delamination strength between the orientation film and the phase difference layer can be determined by delaminating the phase difference layer and observing which interface the delamination occurs at. The interface at which the delamination occurs can be analyzed, for example, by IR.
[0180] Furthermore, one embodiment of the transfer laminate 40 shown in the example of Figure 6 is a transfer laminate in which a phase difference layer 31 is laminated on a second substrate 32 as a support 35 that resiliently supports the phase difference layer, and a phase difference layer 36 for transfer, in that order.
[0181] The following describes this embodiment, but the phase difference layer can be the same as the phase layer described in "D. Phase Difference Film" above, so its description will be omitted here. Also, the alignment film and substrate can be the same as the alignment film and substrate described in "D. Phase Difference Film" above, but the following methods can be used to adjust the peel strength.
[0182] To obtain the transfer laminate 20 shown in the example in Figure 4, if the peel strength between the second substrate 12 and the alignment film 13 is greater than the peel strength between the alignment film 13 and the phase difference layer 11, for example, a method can be used in which the solvent contained in the alignment film forming composition is capable of dissolving the second substrate. Preferably, a resin substrate is used as the second substrate, and surface treatment to improve adhesion to the substrate surface may also be performed. In such a case, the adhesion between the resin substrate and the alignment film can be improved. Furthermore, in order to reduce the peel strength between the alignment film and the phase difference layer so that the peel strength between the substrate and the alignment film is greater than the peel strength between the alignment film and the phase difference layer, it is also preferable to make the solvent resistance of the alignment film relatively high. When the solvent resistance of the alignment film is relatively high, when the polymerizable composition is applied to the alignment film to form the phase difference layer, the alignment film becomes less likely to dissolve in the solvent in the polymerizable composition, thus reducing the adhesion between the alignment film and the phase difference layer.
[0183] On the other hand, in order to obtain the transfer laminate 30 shown in the example of Figure 5, the peel strength between the second substrate 22 and the alignment film 23 may be made smaller than the peel strength between the alignment film 23 and the phase difference layer 21. For example, the surface of the substrate may be treated with a release agent, or a release layer may be formed. This improves the peelability of the substrate, and the peel strength between the substrate and the alignment layer can be made smaller than the peel strength between the alignment layer and the phase difference layer. Examples of release agents include surface treatments such as fluorine treatment and silicone treatment. Examples of materials for the release layer include fluorine-based release agents, silicone-based release agents, and wax-based release agents. Examples of methods for forming the release layer include applying the release agent by coating methods such as dip coating, spray coating, and roll coating. Also, in order to obtain the transfer laminate 40 shown in the example of Figure 6, the surface of the substrate may be treated with a release agent, or a release layer may be formed, as necessary.
[0184] The substrate used in the transfer laminate may or may not be flexible, but it is preferable that it be flexible in order to make it easier to peel off. The thickness of the substrate used in the transfer laminate is usually in the range of 20 μm to 200 μm in the case of a sheet of the above material, taking into account a balance between sufficient self-supporting strength and flexibility that can be adapted to the manufacturing and transfer process of the transfer laminate of this embodiment.
[0185] The phase difference layer that can be provided from the transfer laminate of this disclosure is suitably used for the same purposes as the phase difference film, for example, suitably used as an anti-reflective quarter-wave plate, can be transferred to optical components for various display devices, and is suitably used to provide thin-film optical components.
[0186] F. Optical component The optical component of the present disclosure comprises a polarizing plate on the phase difference film of the present disclosure.
[0187] The optical member of this embodiment will be described with reference to the figures. Figure 7 is a schematic cross-sectional view showing one embodiment of the optical member. In the example of the optical member 60 in Figure 7, a polarizing plate 50 is arranged on the phase difference film 10 of the present disclosure. An adhesive layer may be provided between the phase difference film 10 and the polarizing plate 50 as needed (not shown).
[0188] In this embodiment, the polarizing plate is a plate-like material that allows only light vibrating in a specific direction to pass through, and can be appropriately selected from conventionally known polarizing plates. For example, polyvinyl alcohol film, polyvinyl formal film, polyvinyl acetal film, ethylene-vinyl acetate copolymer saponified film, etc., dyed with iodine or dye and stretched can be used. In addition, in this embodiment, the adhesive or bonding agent for the adhesive layer can be appropriately selected from conventionally known ones, and any bonding form such as pressure-sensitive adhesives, two-component curing adhesives, ultraviolet curing adhesives, thermosetting adhesives, and heat-melt adhesives can be suitably used.
[0189] The optical component of this embodiment may further include, in addition to the polarizing plate, other layers that are present in known optical components. Examples of such other layers include, but are not limited to, other phase difference layers different from the phase difference layer of this embodiment, as well as anti-reflective layers, diffusion layers, anti-glare layers, anti-static layers, protective films, etc.
[0190] The optical element of this embodiment can be suitably used, for example, as an optical element that suppresses external light reflection, or as a wide-viewing-angle polarizing plate for various display devices.
[0191] The method for manufacturing the optical component of this disclosure is not particularly limited, and any method of laminating a polarizing plate on the phase difference film of this disclosure can be appropriately selected and used. For example, a manufacturing method in which a polarizing plate is laminated on the phase difference film of this disclosure via an adhesive layer or bonding layer can be used.
[0192] Furthermore, a method for manufacturing an optical member according to one embodiment of the present disclosure includes a transfer laminate preparation step of preparing the transfer laminate of the present disclosure, a transfer step of placing a transfer target including at least a polarizing plate and the phase difference layer of the transfer laminate facing each other and transferring the transfer laminate onto the transfer target, and a peeling step of peeling the support from the transfer laminate transferred onto the transfer target.
[0193] According to the method for manufacturing an optical member of one embodiment of the present disclosure using the transfer laminate, an optical member can be obtained that comprises a polarizing plate and only the phase difference layer of the phase difference film of the present disclosure. The transfer laminate used in the method for manufacturing an optical member of one embodiment of the present disclosure can be the same as that described in "E. Transfer Laminate" above, so its description is omitted here. In addition, the object to be transferred used in the method for manufacturing an optical member of one embodiment of the present disclosure typically includes an adhesive layer and a polarizing plate, but is not limited to these, and may further include layers similar to the other layers that the optical member of one embodiment of the present disclosure may have.
[0194] G. Display Device The display device according to this disclosure is characterized by comprising the phase difference film of the above embodiment or the optical member of the above embodiment. Examples of display devices include, but are not limited to, light-emitting display devices and liquid crystal display devices.
[0195] In particular, because it includes the phase difference film or optical member of this embodiment, it has the effect of improving the viewing angle while suppressing external light reflection in light-emitting devices such as organic light-emitting devices that have a transparent electrode layer, a light-emitting layer, and an electrode layer in that order.
[0196] An example of a light-emitting display device, which is one embodiment, will be described with reference to the figures. Figure 8 is a schematic cross-sectional view showing one embodiment of an optical member. In the example of the organic light-emitting display device 100 in Figure 8, a polarizing plate 50 is arranged on the light-emitting surface side of the phase difference film 10, and on the opposite side, a transparent electrode layer 71, a light-emitting layer 72, and an electrode layer 73 are arranged in this order. As the light-emitting layer 72, for example, a configuration in which a hole injection layer, a hole transport layer, a light-emitting layer, and an electron injection layer are stacked in the order from the transparent electrode layer 71 side can be cited. In this embodiment, the transparent electrode layer, hole injection layer, hole transport layer, light-emitting layer, electron injection layer, electrode layer, and other components can be any known components as appropriate. The light-emitting display device manufactured in this way can be applied to both passively driven organic EL displays and actively driven organic EL displays, for example. Note that the display device of this embodiment is not limited to the above configuration, and can be any known configuration selected as appropriate.
[0197] Examples and comparative examples are shown below to further illustrate this disclosure. Each compound produced was prepared using JEOL JNM-LA400WB manufactured by JEOL Ltd. 1 The chemical structure was confirmed by 1H NMR measurement. Furthermore, the phase transition temperature of each fabricated compound was confirmed during heating by texture observation using a polarizing microscope (Olympus BX51) equipped with a temperature control stage. C represents the crystalline phase, N represents the nematic phase, and I represents the isotropic liquid phase. For example, "C 130 N 180 I" indicates that the crystalline phase transitioned to the nematic phase at 130°C, and the nematic phase transitioned to the isotropic liquid phase at 180°C.
[0198] In this disclosure, unless otherwise specified, all parameters shall be values measured at a temperature of 25°C ± 2°C and a relative humidity of 40% to 65%. Furthermore, before starting each measurement, the target sample shall be exposed to the above atmosphere for at least 30 minutes before measurement and evaluation.
[0199] Furthermore, in this disclosure, unless otherwise specified, the orientation and in-plane phase difference Re in the evaluation items below refer to the average value of nine measured values. The nine measurement points are determined by drawing lines that divide the area inside the margin (1 cm from the outer edge of the measurement sample) into four equal parts in the vertical and horizontal directions, and using these nine points as the measurement centers. If the measurement sample is a rectangle, the area inside the margin (1 cm from the outer edge of the rectangle) is used as the margin, and measurements are taken at the nine points at the intersections of the lines that divide the area inside the margin into four equal parts in the vertical and horizontal directions, and the average value is calculated. If the measurement sample is a shape other than a rectangle, such as a circle, ellipse, triangle, or pentagon, draw a rectangle with the largest area that can be inscribed in this shape, and perform nine measurements on this rectangle using the method described above. If at least one side of the rectangle of the measurement sample is 5 mm or less, any seven locations inside the rectangle will be used as the measurement centers, and the average value of the five measurements obtained by excluding the maximum and minimum values from the seven measurements will be used.
