More specifically, it relates to a vertical alignment type liquid crystal alignment agent which exhibits good printability and is excellent in various electrical characteristics, and a liquid crystal display element having a vertical alignment type liquid crystal alignment film. [Prior Art] At present, as a liquid crystal display element, a TN type liquid crystal display element having a so-called TN type (Twisted ί Nematic) liquid crystal cell is known, which is formed on the surface of a substrate on which a transparent conductive film is provided with poly-proline, polyfluorene A liquid crystal alignment film formed of an imide or the like is used as a substrate for a liquid crystal display element, and two substrates are arranged to face each other, and a nematic liquid crystal layer having positive dielectric anisotropy is formed in the gap to form a sandwich structure. The unit cell, the long axis of the liquid crystal molecules is continuously twisted 90 degrees from one substrate to the other substrate. Further, an STN (Super Twisted Nematic) type liquid crystal display element and a ? vertical alignment type liquid crystal display element having a higher contrast ratio than the TN type liquid crystal display element and having less viewing angle dependency have been developed. The STN-type liquid crystal display device uses a chiral agent in which a photoactive material is mixed in a nematic liquid crystal as a liquid crystal, and uses birefringence generated by causing a long axis of liquid crystal molecules to be continuously twisted by 180 degrees or more between substrates. effect. In recent years, the development of new liquid crystal display elements has also been active. As one of them, a horizontal electric field type liquid crystal display element has been proposed in which two electrodes for driving liquid crystals are arranged in a comb shape on one side substrate to generate a substrate. 200804936 Parallel electric field, controlling liquid crystal molecules. This element is generally called a planar switching type (IPS type) and is known to have excellent wide viewing angle performance. And recently, the use of an optical compensation film has further improved the wide viewing angle performance, and it has a remarkable feature of obtaining a wide viewing angle which is comparable to a cathode ray tube which has no tone inversion and color tone change. As a liquid crystal display element other than the above, it is proposed that a liquid crystal molecule having a negative dielectric anisotropy is vertically aligned on a substrate, and is referred to as a MVA (Multi domain Vertical Alignment) type or a PVA (Patterned V ertica 1 A1 ignment) type. Alignment type liquid crystal display element. These ΜVA type or PVA type liquid crystal display elements are not only excellent in viewing angle and contrast, but also need not be subjected to rubbing treatment in forming a liquid crystal alignment film, and are excellent in terms of manufacturing engineering. Conventionally, as these liquid crystal alignment films, polyacetamide or a dehydrated ring-closed polyimine is used for many liquid crystal display elements in any of various display modes because of heat resistance, affinity with liquid crystals, or mechanical strength. . At present, a liquid crystal alignment film of a vertical alignment type liquid crystal display element is formed by applying a liquid crystal alignment agent onto a substrate as described in Patent Document 1. As a basic property, it is necessary to have a vertical alignment property which enables vertical alignment of liquid crystals. In recent years, with the expansion of the vertical alignment type liquid crystal display element, the demand for improvement in display quality and productivity improvement by the vertical type liquid crystal alignment film has been increasing. The characteristics required for the alignment film are also various. Among them, as the most important characteristics, as described in Patent Documents 1 to 4, an improvement in high voltage holding performance and good coating property to a substrate can be cited. In order to achieve high voltage holding performance, it is known that the polyimine used in the alignment film has a high sulfhydryl imidization ratio as described in Patent Document 5. However, since the solubility of the hydrazine imidization is lowered in the solvent, the range of the solvent which can be used is limited, and as a result, it is difficult to achieve good coatability. As described above, the improvement of the imidization ratio of the high voltage holding property can be caused, and the coating property is greatly deteriorated, which is a trade-off relationship.

(Molecular weight: about 400; additive A), a solution having a solid concentration of 6 wt% was prepared. The solution was visually observed to obtain a turbid transparent solution, and thus it was confirmed that it showed good solubility. Subsequently, the film-forming composition of the present invention was prepared by filtration using a filter having a pore size of 0.2 /z m. Then, the printability was evaluated, and no unevenness or unevenness in coating was observed on the coating film, and it was confirmed that the film had good printability. Then, the film-forming composition of the present invention was prepared in the same manner as above except that the solid content concentration was 4%. Next, the film-forming composition was applied onto a transparent conductive film made of an ITO film provided on one surface of a glass substrate having a thickness of 1 mm by a spin coater, and dried at 200 ° C for 60 minutes to form a dry film thickness of 0.08 μ. The film of m. Next, on each of the outer edges of the liquid crystal alignment film of the liquid crystal alignment film coating substrate of the pair of transparent electrode/transparent electrode substrates, an epoxy resin adhered to an alumina ball having a diameter of 3.5 // m is applied. After the mixture is mixed, the liquid crystal alignment film faces are gradually combined and pressure-bonded, and the adhesive is cured. Next, the nematic liquid crystal (MLC-6608, manufactured by Merck & Co., Ltd.) was filled between the substrates through the liquid crystal injection port, and then the liquid crystal injection port was closed with an acrylic photocurable adhesive, and bonded to both sides of the substrate. A polarizer is used to produce a liquid crystal display element. The vertical alignment property of the obtained liquid crystal display element was evaluated to be good.
