PURPOSE: To obtain a compsn. for a liquid crystal oriented film with which a high pretilt angle is obtd. and uneven luminance or uneven afterimages are hardly produced even when the compsn. is baked at low temp. by incorporating a specified polymerized material.
CONSTITUTION: This compsn. for a liquid crystal oriented film is formed between a transparent electrode and a liquid crystal layer and contains a polymerized material obtd. by the reaction of carboxylic acid and a diamine compd. expressed by an ortho-ortho structure. The diamine compd. having an ortho- ortho structure contains a compd. expressed by formula. In formula, Ri (i=1 to 4) and Rj (j=1 to 4) are independently hydrogen atoms, alkyl groups, cycloalkyl groups, alkoxy groups or halogen atoms, and may be same or different. Rm and Rn are independently hydrogen atoms, alkyl groups, halogenated alkyl groups or phenyl groups and may be same or different.
