摘要：
An embodiment of the present invention provides a thermosetting composition with a photo-alignment property, including a copolymer containing a photo-alignment constitutional unit, and a thermal cross-linking constitutional unit in which a thermal cross-linking group is bonded via a straight-chain alkylene group with a carbon number of 4 to 11, or via a polyethylene glycol group with a cycle number of 2 to 5.
