Abstract: A display apparatus includes: a first substrate; a bank on the first substrate and including partition walls defining a first well, a second well, a third well, and auxiliary wells, a first quantum dot layer in the first well; and a second quantum dot layer in the second well. The partition walls have a second width that is less than a first width. The first width is an average width of the partition walls farther away from a cross point at where three or more partition walls extending in different directions meet one another, and the second width is an average width of the partition walls at the cross point; a first quantum dot layer in the first well; and a second quantum dot layer in the second well.

Abstract: A method of manufacturing a deposition mask is disclosed. In one aspect, the method includes depositing a first photoresist layer on a substrate, aligning a first photomask over the first photoresist layer and developing the first photoresist layer to form a plurality of first photoresist patterns having sides that gradually narrow toward the substrate. The method also includes forming a metal layer over the first photoresist patterns and a portion of the substrate exposed by the first photoresist patterns, depositing a second photoresist layer over the metal layer and aligning a second photomask over the second photoresist layer and developing the second photoresist layer to form a plurality of second photoresist patterns between the first photoresist patterns. The method further includes etching the metal layer to form a pattern hole, removing the first and second photoresist patterns and separating the substrate so as to form a deposition mask.
