Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of producing a liquid crystal display element, a polymer composition, and a liquid crystal display element. More specifically, the present invention relates to a novel method for manufacturing a liquid crystal display element having a wide viewing angle and a fast response speed. [Prior Art] In a liquid crystal display device, a M VA (Multi-domain Vertical Alignment) type panel known as a vertical alignment method forms a protrusion in a liquid crystal panel and thereby defines liquid crystal molecules. Falling in the direction 'to achieve the expansion of the viewing angle. However, according to this aspect, the lack of light transmittance and contrast from the projections cannot be avoided, and there is also a problem that the response speed of the liquid crystal molecules is slow. In recent years, in order to solve the problem of the MVA type panel as described above, a P S A (polymeric stable alignment (p 01 ym er s u s t ai n ed A1 i gnmen t) mode has been proposed. The PSA mode is in a gap between a pair of substrates formed by a substrate having a patterned conductive film and a substrate having a patterned conductive film, or a pair of substrates formed by two substrates having a patterned conductive film. In the gap, a liquid crystal composition having a polymerizable compound is applied, and a polymer is irradiated with ultraviolet rays in a state where a voltage is applied between the conductive films to polymerize the polymerizable compound, thereby exhibiting a pretilt angle characteristic and controlling the alignment direction of the liquid crystal. . According to this technique, by forming the conductive film into a specific structure, the expansion of the viewing angle and the speed of response of the liquid crystal molecules can be realized, thereby solving the problem of insufficient transmittance and contrast in the MVA type panel. However, in the PSA mode 201141950, in order to polymerize the polymerizable compound, it is necessary to irradiate a large amount of ultraviolet rays such as 100,000 J/m 2 , thereby causing a problem of decomposition of liquid crystal molecules, and further, 'unreacted compounds which are not polymerized by ultraviolet irradiation. Residual in the liquid crystal layer 'these phases cause display unevenness, and have an adverse effect on the voltage holding characteristics, or cause problems in the long-term reliability of the panel, and have not been practical yet. The non-patent document 1 proposes a method of using a liquid crystal alignment film formed of a polyimine-based liquid crystal alignment agent containing a reactive mesogen. According to Non-Patent Document 1, the response of the liquid crystal molecules of the liquid crystal display element having the liquid crystal alignment film formed by such a method is high. However, in Non-Patent Document 1, there is no description as to what kind of reactive mesogens are used in what amount, and the amount of ultraviolet irradiation required is still large, and problems related to display characteristics, particularly voltage holding characteristics, cannot be eliminated. . In this regard, a related art using the updated display mode instead of the above PSA mode has recently been proposed (Patent Document 1). The technique is to irradiate a polyimide film having a photofunctional cinnamate structure with a non-polarized ultraviolet ray and to utilize a molecular rotation generated by photoisomerization of the cinnamate structure to achieve desired Pretilt performance. However, in order to impart a desired pretilt performance, it is necessary to irradiate a considerable amount of ultraviolet rays, and the working time when the liquid crystal display is manufactured becomes long, or the electrical characteristics of the formed liquid crystal alignment film are generated due to strong ultraviolet rays. In particular, the disadvantage of impaired voltage retention.

The method is achieved by: coating a polymer composition containing (A) a polymer and (B) an organic solvent on the conductive film of a pair of substrates having a conductive film to form a coating film; a pair of substrates of the coating film are disposed opposite to each other with a liquid crystal molecular layer interposed therebetween, and the coating film is opposed to each other to form a liquid crystal cell; and the liquid crystal cell is applied to a state in which a voltage is applied between the conductive films having the pair of substrates Row light irradiation; characterized in that the (A) polymer comprises: 201141950 (A1) a polymer having both a structure and a polymerizable unsaturated bond, which is a radical generated by light irradiation.
