The invention is to provide a photosensitive compound suitable for a photoalignment method, a photosensitive polymer prepared from the compound, a photoaligning agent by using the compound and a liquid crystal alignment film prepared from the photoaligning agent. A photosensitive compound represented by formula (1):
in formula (1), Y
1
is a divalent group represented by formula (2-1) or (2-2); A
1
is 1,4-phenylene or 1,4-cyclohexylene; Z
1
is a single bond, —COO— or —OCO—; R
1
and R
2
are each independently hydrogen, fluorine or alkyl having 1 to 5 carbons; Q
1
is independently a single bond or alkylene having 1 to 12 carbons; and n is 0 or 1. In formulas (2-1) and (2-2), W
1
and W
2
are each independently hydrogen, alkyl having 1 to 3 carbons or alkoxy having 1 to 3 carbons.
