Producing method of liquid crystal display element, polymer composition and liquid crystal display element

The present invention relates to a manufacturing method of a liquid crystal display element, a polymer composition and a liquid crystal display element. The invention provides the manufacturing method for the liquid crystal display element which has the following advantages: wide visual angle, high response speed of liquid crystal element, excellent display characteristic and excellent long-term reliability. The manufacturing method of the liquid crystal display element is characterized by comprising the following steps: respectively coating a polymer composition which comprises (A) polyamic acid and/or polyimide with a group that is represented by a formula (A-I) and (B) an organic agent on conductive films of a pair of substrates with the conductive films for forming coating films; oppositely equipping the pair of substrates with the coating films through the liquid crystal module layers so the coating films are opposite from each other thereby forming a liquid crystal box; and performing light irradiation for the liquid crystal box at a state that a voltage is performed between the conductive films of the pair of substrates (wherein in the formula (A-I), R is a hydrogen atom or methyl, Y1 and Y2 respectively represent an oxygen atom or sulphur atom).
