Abstract: A manufacturing method of a display device includes: forming a transistor on a substrate; forming an organic insulating layer on the transistor; and performing a plasma treatment on the organic insulating layer. The organic insulating layer includes an acryl-based polymer, and the plasma treatment is performed by using helium gas or argon gas.
