Abstract: A method for manufacturing a display device allows an opening pattern that opens at least some areas on a pixel defining layer between sub-pixels to be exposed to a strip solution in a process of stripping off a photoresist film and a protective film disposed on a light emitting layer, thereby increasing a dissolution speed of the protective film and reducing a difference in the dissolution speed of areas to improve uniformity of the process. In addition, in the display device of the present disclosure, a dummy light emitting layer formed on the pixel defining layer between the sub-pixels may interrupt a current flow between the sub-pixels adjacent to each other, thereby reducing a lateral leakage current that may occur between pixels adjacent to each other.
