Abstract:
Provided is a method of manufacturing a polyimide substrate. An acid solution is provided to a glass substrate to remove a first cation included in the glass substrate, and a source solution including polyamic acid is provided to the glass substrate. Then, the polyamic acid is cured to form a polyimide substrate on the glass substrate, and the polyimide substrate is separated from the glass substrate.
