The present invention provides an orientation film, an orientation film material, a liquid crystal display having the orientation film, and a method for forming the same. The orientation film material comprises a first polyimide (p1) precursor, a second polyimide (p2) and precursor thereof, and a vinyl monomer. The vinyl monomer is represented by general formula (1). P1-A1-(Z1-A2)n-P2 (1) (In general formula (1), P1 and P2 are independently acrylate, methacrylate, acrylamide, or methacrylamide; A1 and A2 are independently 1,4-phenylene, 1,4-cyclohexane, or 2,5-thiophene, or napthalene-2,6-diyl or anthracene-2,7-diyl; A1 and / or A2 are substituted by at least one fluorine group; Z1 is a -COO-, -OCO-, -O-, or -CONH- group or a single bond; and n is 0 or 1.).
