(Problem) Providing the photosensitive compound and the photosensitive polymer which consisted of this compound in the photo-alignment method. Provision of the photo-alignment agent using this compound, and the liquid crystal aligning film using the photo-alignment agent. (Solution means) The 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-, -OCO-, and R 1 and R 2 are independently hydrogen, fluorine or C 1? 5 is alkyl, and Q 1 is independently a single bond or C 1? 12 is alkylene and n is 0 or 1; In formula (2-1) and (2-2), W < 1> and W < 2> are hydrogen, C1-C? Alkyl of 3 or 1? 3 is alkoxy. |
