| 摘要 |
The invention relates to a liquid crystal aligning agent, process for forming a liquid crystal aligning film, liquid crystal display device, process for producing the liquid crystal display device. The invention provides the liquid crystal aligning agent, capable of providing a liquid crystal aligning file with excellent stability of the inclination angle obtained by an optical aligning method changed with the time. The liquid crystal aligning agent contains a radioactivity-induced linear polysiloxane with the structure represented by the following formula (1). The radioactivity-induced linear polysiloxane is preferably a reacting product of (a) polysiloxane with a epoxy radical and (b) a compound with the structure represented by the formula (1) and a carboxyl or a compound with the group represented by the following formula (2). -CC-COOH (2). |
