Abstract
The present invention relates to a liquid crystal aligning agent which contains a reaction product of at least one selected from the group consisting of a polysiloxane having a structure represented by the following formula (S-1), a hydrolysate thereof and a condensate of the hydrolysate and a compound represented by the following formula (1): (Yin the formula (S-1) is a hydroxyl group, an alkoxyl group having 1 to 10 carbon atoms, an alkyl group having 1 to 6 carbon atoms or an aryl group having 6 to 10 carbon atoms, R in the formula (1) is a group having an alkyl group with 4 to 20 carbon atoms, a fluoroalkyl group with 1 to 20 carbon atoms or a cyclohexyl group, or a group having 17 to 51 carbon atoms and a steroid skeleton, and Xin the formula (S-1) and Z in the formula (1) are reacted with each other to form a bond group for bonding the silicon atom in the formula (S-1) to R in the formula (1)).
