Claim:
1. A method for forming a resist film, comprising the steps of: forming a first resist film on a light shielding film formed on a substrate, by using a spin coating method; forming a protective film on the first resist film; simultaneously removing a region of the protective film and a region of the first resist film corresponding to the region of the protective film, and exposing a portion of the light shielding film; forming a second resist film on the protective film and an exposed portion of the light shielding film on the substrate using a spin coating method, and providing a first region in which the second resist film is formed on the light shielding film and a second region in which the second resist film is formed on the protective film; and separately forming a region in which the first resist film is provided on the light shielding film and a region in which the second resist film is provided on the light shielding film, by simultaneously removing the protective film and the second resist film in the second region.
