Abstract:
1. A method of manufacturing a display device, wherein an organic passivation film is formed, the method comprising the steps of: coating a chemical amplification photosensitive resin composition comprising an acrylic resin having a molecular weight of 4,000 to 20,000 as a base material, the chemical amplification photosensitive resin composition containing 1 to 4 wt % of a photoacid generator, and prebaking the chemical amplification photosensitive resin composition to cure the coated composition; exposing the cured chemical amplification photosensitive resin composition by using a mask and developing the same; subjecting the developed chemical amplification photosensitive resin composition to post exposure at an exposure dose of 500 mJ/cm subsequently, heating the post-exposed composition at 220 to 250° C.
