The invention relates to a diamine compound, a polyaminic acid or a polyimine prepared by using the same, a liquid crystal alignment agent using the polymer, and the like. A liquid crystal display element using an alignment film of the alignment agent. [Prior Art] The liquid crystal display element has evolved from a twisted nematic (TN) to a super twisted nematic type (Twisted Nematic 'TN) with the requirements for display quality and response speed such as enlargement and colorization of the facet, and improvement in contrast and light emission. Nematic, STN) 'and further developed into a single film of Thin Filmed Transistor 'TFT' display elements. In recent years, the driving method of TFT-type display elements has been continuously improved. For example, in order to further expand the viewing angle, an In Plane Switching (IPS) method and a Vertical Alignment (VA) method have been developed, and OOptically Compensated Bend (OCB) mode that maintains response speed. The alignment film achieves two effects of aligning the liquid crystal molecules in the liquid crystal display element in a certain direction and being inclined with respect to the plane of the substrate (forming a pretilt angle). The tilt of the liquid crystal molecules with respect to the substrate plane is referred to as a pretilt angle. This name is also used in the following book. In the alignment film, in order to minimize the long-term, chemical, and thermal deterioration of the molecular alignment, the material mainly uses a polyimide film having a glass transition point (Tg), a good resistance, and a heat resistance. A solution containing polylysine or soluble polyimine (so-called liquid crystal alignment agent) is usually applied to a substrate having an electric 15190 pif.d〇c electrode by a spin coating method or a printing method, and the substrate is heated. The polyphthalamide is dehydrated, closed, or the solvent of the soluble polyimine solution is evaporated to obtain a polyimide film, and further subjected to an alignment treatment step such as rubbing orientation to obtain an alignment film. The above alignment film is required to have the following effects for the liquid crystal display element. (1) The liquid crystal molecules can be formed into a suitable pretilt angle. In addition, the pretilt angle varies little with the thrust intensity or the temperature difference of the heating. (2) The liquid crystal display element can be subjected to alignment processing in which no alignment defect occurs. (3) It is possible to give the liquid crystal display element a suitable voltage holding ratio (v〇hage

(4) It is not easy to cause a so-called "burn-in" phenomenon. That is, when the liquid crystal display element displays an arbitrary image for a long time and then converts it to another image, the phenomenon of the previous image remains. Caused by the delay phenomenon of the bipolar electric layer generated by the application of voltage, or the residual charge generated by the localization of the charged ions such as ions contained in the liquid crystal display element due to voltage application, or due to the liquid crystal Caused by low alignment control. In particular, in the STN method in which the liquid crystal twist angle between the substrates is large, or the IPS liquid crystal display element in which the electric field direction applied to the liquid crystal is substantially parallel to the substrate interface using the hanging electrode, the alignment film having a large liquid crystal alignment control force is highly desirable. 0 In particular, when the display element of the IPS method is intended to perform black display, the light leakage is small (the black balance is good). In order to make the black balance good, the alignment film 15190pif.doc material not only needs to have a large control force for the liquid crystal alignment as described above, but also can perfectly conform to the alignment direction of the surface of the crucible by the rubbing direction. Further, in recent years, with the low voltage of the driving voltage, the electric induction rate anisotropy is gradually used, and the problem of display fluctuation (luminance fluctuation) in the display surface cannot be ignored. In particular, when water is washed in order to remove the residue generated when the alignment film is treated by rubbing, there is a case where display fluctuations occur due to the washing marks, which becomes a big problem. JP-A-H11-322925 discloses that a polymer having a structural unit of the formula (A) can be used as a liquid crystal alignment film. However, there is no description about the use of this polymer as a property of liquid crystal alignment.
