Display apparatus

A display apparatus comprising:

• a lower substrate comprising a display area including a first edge, a second edge, a third edge, and a fourth edge, the second edge facing the first edge, the third edge connecting an end of the first edge to an end of the second edge, and the fourth edge connecting another end of the first edge to another end of the second edge;
• a first light-emitting device, a second light-emitting device, and a third light-emitting device in the display area on the lower substrate, each of the first to third light-emitting devices including an emission layer emitting light having a wavelength within a wavelength band;
• an upper substrate above the lower substrate with the first to third light-emitting devices disposed between the upper substrate and the lower substrate;
• a second-color color filter layer on a lower surface of the upper substrate, the lower surface of the upper substrate facing the lower substrate, wherein the second-color color filter layer includes a first opening overlapping the first light-emitting device and including edges that are not parallel to the first to fourth edges, and a second opening overlapping the third light-emitting device and including edges that are not parallel to the first to fourth edges;
• a first-color color filter layer on the lower surface of the upper substrate, wherein the first-color color filter layer fills the first opening and includes a third opening and fourth opening, the third opening overlapping the second light-emitting device and including edges that are not parallel to the first to fourth edges in a plan view, the fourth opening overlapping the third light-emitting device and including edges that are not parallel to the first to fourth edges in the plan view;
• a third-color color filter layer on the lower surface of the upper substrate, the third-color color filter layer filling the second opening and the fourth opening;
• a bank between the first to third-color color filter layers and the lower substrate, and including a fifth opening, a sixth opening, and a seventh opening, wherein the fifth opening overlaps the first light-emitting device and includes edges that are parallel to the first to fourth edges in the plan view, a sixth opening overlaps the second light-emitting device and includes edges that are parallel to the first to fourth edges in the plan view, and a seventh opening overlaps the third light-emitting device and includes edges that are parallel to the first to fourth edges in the plan view;
• and
• quantum dot layers filling two of the fifth to seventh openings.
