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.
