1. A display apparatus comprising:
a bottom substrate;
a first light-emitting element over the bottom substrate and comprising a second-color emission layer;
a top substrate over the bottom substrate with the first light-emitting element therebetween and comprising a first region corresponding to the first light-emitting element;
a second-color color filter layer on a bottom surface of the top substrate facing the bottom substrate, the second-color color filter layer having a 2-1st opening that exposes the first region;
a first-color color filter layer comprising a portion in the 2-1st opening and a portion on a bottom surface of the second-color color filter layer facing the bottom substrate;
a bank between the first-color color filter layer and the bottom substrate and between the second-color color filter layer and the bottom substrate, the bank having a first opening that corresponds to the first region, the first opening comprising a 1-1st portion overlapping the 2-1st opening and a 1-2nd portion outside the 2-1st opening when viewed from a direction normal to the bottom surface of the top substrate;
a first-color quantum dot layer in the first opening; and
a first reflective layer on an inner surface of the first opening of the bank and on a portion of a top surface of the first-color quantum dot layer facing the top substrate, the portion of the top surface of the first-color quantum dot layer corresponding to the 1-2nd portion.
