Abstract
This invention relates to a mask, a method of fabricating the same, and a method of fabricating organic electro-luminescence device using the same that is capable of minimizing a difference of a rigidity coefficient value of both an open part and a blocking part. The mask includes: an open part formed in a hole type to pass an organic material for forming a first organic layer on a substrate; and a blocking part having a plurality of grooves formed at other areas except for the open part.
