摘要：
A deposition mask for manufacturing an organic light emitting display (OLED) using the same are provided. The deposition mask is intended for preventing an organic film from being damaged due to touching of a blocked-off portion of the mask to an emission layer (EML), or chemical transition from being generated at the organic film. For that purpose, the deposition mask stuck to a substrate of the OLED to deposit an organic EML includes an opening and an indentation. The opening is opened so as to deposit the organic EML. The indentation is indented a predetermined depth from a plane facing the substrate.
