ABSTRACT:
A shadow mask for uniformly forming an organic luminescent layer of an organic electroluminescent device is disclosed. The shadow mask includes a plurality of striped slots aligned in one direction, the striped slots having a plurality of inclined surfaces formed on each side thereof. Due to a step difference, the inclined surfaces prevent shadows from occurring, thereby uniformly forming the organic luminescent layer.
