Abstract
A display apparatus includes a cover plate and a display substrate. The cover plate includes a first base substrate, a black matrix and a support layer stacked on a side of the first base substrate, and a quantum dot layer disposed on the side of the first base substrate. The black matrix and the support layer each have a plurality of openings to form a plurality of opening regions. The quantum dot layer includes a plurality of quantum dot units. Each quantum dot unit is located in an opening region in the plurality of opening regions. The display substrate includes a second base substrate, driving circuit structures disposed on a side of the second base substrate, and light-emitting devices disposed on a side of the driving circuit structures. Each light-emitting device is coupled to a driving circuit structure in the driving circuit structures to emit light.
