By forming a layer and orienting it in a liquid crystal state, the present inventors have newly found that the liquid crystal compound can be oriented in a direction perpendicular to the orientation substrate surface, and have reached the present invention. Disclosure of the invention
- the layer of an inorganic substance used for the substrate for vertical alignment of the present invention may be a layer in which the substrate itself is formed of an inorganic compound, such as a glass plate, or a layer formed on a plastic film by vapor deposition, sputtering, coating, or the like.
- an inorganic compound such as aluminum and silver
- an inorganic compound such as silica and aluminum oxide.
- Aluminum, aluminum oxide and silver are particularly preferable.
- Aluminum and aluminum oxide are not strictly classified, meaning that, for example, when aluminum is deposited on a polymer film, the surface of the deposited layer is oxidized to form aluminum oxide.
- the thickness of the inorganic substance layer is not particularly limited as long as it is formed as a uniform film to some extent, but is preferably about 10 nm to 10 ", more preferably about 0.01 m to 5 am It is preferable that the surface of the layer of the inorganic substance is smooth so as not to affect the orientation of the finally formed liquid crystal compound layer.
- Examples of the substrate used for the substrate for vertical alignment of the present invention include an inorganic compound such as the above-mentioned glass plate and a polymer film.
- a polymer film it is smooth enough not to affect the orientation of the liquid crystal compound layer to be finally formed, when forming an inorganic substance layer, and further forming an acrylic polymer layer on it.
- it has excellent workability. That's it Examples of such polymer films include films made of polyester, polycarbonate, polyarylate, polyether sulfone, triacetyl cellulose, cycloolefin polymer, and the like.
- the acryl polymer used for the substrate for vertical alignment of the present invention is a copolymer of a (meth) acrylate ester and another copolymerizable compound.
- the main component (meth) acrylates include methyl (meth) acrylate, ethyl (meth) acrylate, propyl (meth) acrylate,
- a suitable hardness can be imparted to the polymer layer, and the solvent resistance can be improved by changing the solvent solubility.
- Other copolymerizable compounds include isoponyl (meth) acrylate, dicyclopentenyloxyshethyl (meth) acrylate, N, N-dimethylaminopropylacrylamide, acryloylmorpholine, and N, N-isopropylacrylamide.
- Various compounds such as acrylamide and N-methylol acrylamide may be added as necessary.
- a crosslinking treatment with a crosslinking agent may be performed.

- a coating method a method in which the solution is prepared by dissolving the compound in a solvent as described below and using a coating apparatus is preferable.
- the solvent used for dissolving the liquid crystal compound varies depending on the solvent solubility of the compound used, the wettability of the applied polymer to the acrylic polymer layer of the vertical alignment substrate, and, for example, toluene and xylene.
- the alignment state can be fixed by irradiating ultraviolet rays at a temperature at which the liquid crystal compound can maintain the alignment state and polymerizing the liquid crystal compound.
- the dose of ultraviolet rays is usually 1 0 0 ⁇ 1 0 0 0 m JZ cm 2 or so, when the air or the polymerization reaction hardly proceeds is irradiated under nitrogen Kiri ⁇ air.
- Example 1 Example 1
- Photopolymerization Initiator Irgacure 907 (Ciba Specialty Chemicals) (12 parts by weight) were dissolved in a mixed solvent of toluene (210 parts by weight) and cyclohexanone (90 parts by weight) to obtain a solid content concentration.
- a solution of a mixture of 25% liquid crystal compounds was prepared. This solution is uniformly applied on one side of the acrylic polymer of the substrate for vertical alignment described above so that the thickness after drying is about 1 m by spinning all over, the solvent is removed by heating, and then a high-pressure mercury lamp (120 W / cm) to produce a vertically aligned liquid crystal retardation film.
- the liquid crystal retardation film (polymerized liquid crystal compound layer) obtained using the glass plate coated with the adhesive was peeled off from the acryl polymer layer of the substrate for vertical alignment, and was transferred to a glass plate.
- the liquid crystal retardation film was transparent.
- the change in retardation value at a wavelength of 590 nm is measured by an automatic birefringence measuring instrument (Oji Scientific Instruments) Manufactured by KQBRA-21 ADH). The results are shown in FIG. From FIG. 1, it was found that the obtained liquid crystal retardation film was oriented in a direction perpendicular to the vertical alignment substrate surface.
- a liquid crystal retardation film was produced in the same manner as in Example 1, except that a glass plate was used instead of the polyester film on which aluminum was deposited. The results are shown in FIG. From FIG. 1, it was found that the obtained liquid crystal retardation film was oriented in a direction perpendicular to the vertical alignment substrate surface.
- the liquid crystal phase difference was obtained in the same manner as in Example 1, except that Paraloid AU-116 (made by Rohm and Haas) was used instead of Paraloid AU-608B (made by Kuchi-Mandhaus). A film was prepared. The results are shown in FIG. From FIG. 1, it was found that the obtained liquid crystal retardation film was oriented in a direction perpendicular to the vertical alignment substrate surface.
