Abstract: A polyamic acid manufacturing system for manufacturing a polyamic acid is disclosed using, as raw materials, a first solution in which a polyaddition-type first polymerizable compound is dissolved and a second solution in which a polyaddition-type second polymerizable compound that reacts with the first polymerizable compound through polyaddition is dissolved. The polyamic acid manufacturing system may include: a first supply part for supplying the first solution; a second supply part for supplying the second solution; a first combining part; and a first reaction part, thereby producing a first polymerization solution in which the polyamic acid is dissolved. Further, the polyamic acid manufacturing system may include: a first supply step of supplying the first solution; a second supply step of supplying the second solution; a first combining step; and a first reaction step, thereby producing a first polymerization solution in which the polyamic acid is dissolved.
