The present invention provides a liquid crystal display device provided with an alignment film having excellent strength/uniformity of alignment regulating force and excellent AC sticking, voltage retention rate, and printing properties, and a liquid crystal alignment agent whereby such an alignment film can be formed. This liquid crystal display device has a pair of substrates, a liquid crystal layer sandwiched between the pair of substrates, and an alignment film disposed between the liquid crystal layer and at least one of the pair of substrates, the alignment film containing a first component and a second component, the first component comprising a reaction product of a polyorganosiloxane having epoxy groups and a compound represented by formula (1) and a compound represented by formula (2), and the second component comprising a polyamic acid and or a polyamide. (1): R1-R2-COO-C6H4-CH=CH-COOH; (2): R3-C6H4-COO-C6H4-CH=CH-COOH (In formula (1), R1 represents a C4-20 alkyl group, and R2 represents a group obtained when two hydrogen atoms are lost from a C6-10 alicyclic hydrocarbon. In formula (2), R3 represents a C1-20 fluorine-containing group.) |
