[Prior Art] The liquid crystal display device is used in a wide range of applications from a small liquid crystal display device such as a mobile phone to a large-screen liquid crystal display device such as a liquid crystal television, because it has a small power consumption and is easy to be miniaturized and flattened. . Regarding the driving mode of the liquid crystal display device, it is known that there is a twisted nematic (TN type) super twisted nematic (STN type), in-plane switching type (IPS type), depending on the change in the alignment state of the liquid crystal molecules. A liquid crystal display element of a liquid crystal cell such as a vertical alignment type (va type). In any of the display modes, the alignment state of the liquid crystal molecules is controlled by the liquid crystal alignment film, so that the properties of the liquid crystal alignment film and the liquid crystal alignment agent which becomes a material of the liquid crystal alignment film affect the performance of the liquid crystal display element. As the material of the liquid crystal alignment agent, for example, in the patent literature, a resin material such as polyacrylic acid, polyimine, polyamine, or polyester is disclosed, in particular, polyglycine or polyruthenium. The liquid crystal alignment film formed of the liquid crystal alignment agent of the material is excellent in affinity, heat resistance, mechanical strength, and the like of the liquid crystal, and is used in a large amount in liquid crystal display elements. However, the use range of 'liquid crystal display elements' has been expanded in recent years, and it is required to continuously drive the liquid crystal display element 201202343 which does not degrade the display quality even for a long time, and liquid crystal display using current polyaminic acid or polyimine. When the element is continuously driven for a long period of time, heat or light may cause deterioration of the liquid crystal alignment film, deterioration of electrical properties, poor alignment of liquid crystal molecules, and the like. In order to solve this problem, a technique of using a large amount of a liquid crystal alignment agent containing a polyfunctional epoxide has been developed (refer to Japanese Laid-Open Patent Publication No. 2008-299318). On the other hand, a substrate including defects such as pores and uneven coating of the coating film which are generated in the production process of the liquid crystal alignment film may be peeled off for reuse (hereinafter, also referred to as "rework"). In this rework, the liquid crystal alignment film is required to have releasability to the substrate. However, if a large amount of the liquid crystal alignment agent containing the above polyfunctional epoxy group is used, the crosslinking property of the liquid crystal alignment film at the time of rework may be lowered due to the crosslinking reaction of the epoxy group at the time of baking. In view of the above, it is desired to develop a liquid crystal alignment film which is capable of suppressing deterioration in display quality due to deterioration of electrical properties or the like even when continuously driven for a long period of time, and which is easily peeled off during rework.

The display mode is VA type. In the case of a liquid crystal display device, the coating film formed as described above can be used as a liquid crystal alignment film as it is, and if necessary, it can be used as a rubbing treatment as described below. When a liquid crystal display element other than the display mode VA type is manufactured, The coating film formed as described above is subjected to a rubbing treatment to form a liquid crystal alignment film. The rubbing treatment is performed on the coating film surface formed as described above by winding a cloth formed of fibers such as nylon, rayon, cotton, etc., in a certain direction.

Two substrates for forming the liquid crystal alignment film were prepared, and liquid crystal cells were fabricated by disposing liquid crystal between the two substrates disposed opposite each other. Here, when the coating film is subjected to the rubbing treatment, the two substrates are disposed to face each other such that the rubbing directions of the respective coating films are at a predetermined angle ', for example, orthogonal or antiparallel. When manufacturing a liquid crystal cell, the following two methods are mentioned, for example. The first method is a currently known method. First, in order to make the liquid crystal alignment films face each other, the two substrates are arranged oppositely by a gap (hereinafter, also referred to as "cell gap"), and two sealants are used. The peripheral portion of the block substrate is bonded to 'fill the injection hole after injecting the liquid crystal into the cell gap divided by the surface of the substrate and the sealant, and the liquid crystal cell can be manufactured. The second method is a method called a DropDF (One Drop Fill) method, in which a predetermined position on one of two substrates forming a liquid crystal alignment film is coated with, for example, an ultraviolet light-curable sealing material, and then After liquid crystal is dropped on the liquid crystal alignment film surface, 'the other substrate is bonded and the liquid crystal alignment film is opposed to each other', and then the entire surface of the substrate is irradiated with ultraviolet light to harden the sealing agent to produce a liquid crystal cell. In the case of any method' The liquid crystal cell produced as described above is reheated until the liquid crystals used are each a homogenous temperature, and then slowly cooled to room temperature. It is preferable to remove the liquid alignment at the time of liquid crystal injection. Then, the liquid crystal display element can be obtained by laminating a polarizing plate on the outer surface of the liquid crystal -30-201202343. The sealant may, for example, be an epoxy resin containing an alumina sphere as a separator and a curing agent. The liquid crystal may, for example, be a nematic liquid crystal or a smectic liquid crystal. Among them, a nematic liquid crystal is preferred. In the case of a VA type liquid crystal cell, a nematic liquid crystal having a negative dielectric anisotropy is preferred. Examples of such a liquid crystal include a dicyanobenzene liquid crystal, a helium trap liquid crystal, a Schiff base liquid crystal, an oxy azo liquid crystal, a biphenyl liquid crystal, a phenylcyclohexane liquid crystal, and the like. When it is a TN type liquid crystal cell or a S TN type liquid crystal cell, a nematic liquid crystal having positive dielectric anisotropy is preferred. Examples of such a liquid crystal include a biphenyl liquid crystal, a phenylcyclohexane liquid crystal, an ester liquid crystal, a terphenyl liquid crystal, a biphenyl cyclohexane liquid crystal, a pyrimidine liquid crystal, and a dioxane. Liquid crystal, bicyclooctane liquid crystal, cubic liquid crystal, and the like. Further, in the liquid crystal, for example, a cholesteric liquid crystal such as cholesteryl chloride, cholesteryl phthalate or cholestyl carbonate may be added, and sold as "C-15" or "CB-15" (Merck). A chiral agent; a strong dielectric liquid crystal such as p-oxybenzylidene-p-amino-2-methylbutyl cinnamate or the like. In the case of a polarizing plate which is bonded to the outer surface of the liquid crystal cell, a polarizing plate formed by a polarizing film called "H film" by sandwiching a polyvinyl alcohol with a cellulose acetate protective film and absorbing iodine may be mentioned. Or a polarizing plate formed by the diaphragm itself. <Polymer Composition> The polymer composition of the present invention comprises [Α] at least one polymer selected from the group consisting of poly-proline and poly-Asian-31 - 201202343 amine, and [B] An oxime ring-containing epoxy compound represented by the formula (I).
