Disclosed is a liquid crystal orientating agent which contains a liquid crystal orientating polyorganosiloxane obtained by reacting a specified reactive polyorganosiloxane typified by the hydrolysis condensate of 2-(3,4-epoxycyclohexyl)ethyltrimethoxysilane and a reactive compound which includes a specified compound typified by stearic acid. The liquid crystal orientating agent of this invention can form liquid crystal orientating films which have excellent liquid crystal orientating properties, a high level of heat resistance and light resistance, exhibit little reduction of voltage retention even in high temperature environments and when irradiated with light of high intensity, and excellent residual image characteristics, and it also has excellent storage stability.

Liquid crystal aligning agent, liquid crystal alignment film and liquid crystal display device

The present invention relates to a liquid crystal aligning agent which contains at least one selected from the group consisting of a polysiloxane having a structure represented by the following formula (S-0) and synthesized through the step of hydrolyzing or hydrolyzing/condensing a silane compound in the presence of an alkali metal compound or an organic base, a hydrolysate thereof and a condensate of the hydrolysate: (in the above formula (S-0), R 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 Yis 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).

Liquid crystal aligning agent, method of producing a liquid crystal alignment film and liquid crystal display device

The present invention relates to a liquid crystal aligning agent containing a radiation sensitive polyorganosiloxane which is obtained by reacting at least one selected from the group consisting of a polyorganosiloxane having a recurring unit represented by the following formula (1), a hydrolysate thereof and a condensate of the hydrolysis with a cinnamic acid derivative having at least one group selected from the group consisting of a carboxyl group, a hydroxyl group, &#x2014;SH, &#x2014;NCO, &#x2014;NHR (R is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms), &#x2014;CH&#x2550;CHand &#x2014;SOCl: (in the formula (1), Xis a monovalent organic group having an epoxy group, and Yis a hydroxyl group, an alkoxyl group having 1 to 10 carbon atoms, an alkyl group having 1 to 20 carbon atoms or an aryl group having 6 to 20 carbon atoms).

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)).
