    摘要: There is provided a process for forming a silicon oxide film which is useful as an electrical insulating film, dielectric film or protective film as used in LSI, thin-film transistor, photoelectric converter, photosensitive body and the like. The process comprises forming a coating film from a polysilane compound represented by the formula SinRm (wherein n is an integer of 3 or more, m is an integer of n to 2n+2, and a plurality of R's are independently a hydrogen atom or an alkyl group) and oxidizing the coating film to form the silicon oxide film.

    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.
