    摘要: A liquid crystal alignment agent containing at least two kinds of polymers selected from the group consisting of polyamic acids and imidized polymers and having a structure obtained by dehydration and ring closure of polyamic acid. In the at least two kinds of polymers contained in the liquid crystal alignment agent, the polymer of higher imidization degree has a smaller surface free energy. The liquid crystal alignment agent gives a liquid crystal display device having less stuck image and high pretilt angle.

    摘要: A stacked film, a method for the production of the stacked film, an insulating film comprising the stacked film, and a substrate for semiconductor, using the insulating film. The stacked film comprises films of two or more kinds of alkoxysilane hydrolysis condensates having 5 nm or more difference in a mean radius of gyration, or films of alkoxysilane hydrolysis condensate having 0.3 or more difference in the dielectric constant. The stacked film is obtained by applying a coating solution comprising (B) a compound having a mean radius of gyration of less than 10 nm, and then applying a coating solution comprising (A) a compound having a mean radius of gyration of from 10 to 30 nm, followed by heating. The stacked film provides a dielectric film (substrate for semiconductor) having superior adhesion to a CVD film.
