Abstract

A display apparatus includes a driving backplane, a plurality of light-emitting elements disposed on the driving backplane, a first light-shielding layer disposed on the plurality of light-emitting elements, and a second light-shielding layer disposed on the first light-shielding layer. The plurality of light-emitting elements include a first light-emitting element and a second light-emitting element. The first light-shielding layer has a first opening and a second opening respectively overlapping the first light-emitting element and the second light-emitting element. The second light-shielding layer has a first opening and a second opening respectively overlapping the first light-emitting element and the second light-emitting element. An area of the first opening of the first light-shielding layer and an area of the second opening of the second light-shielding layer are substantially the same. An area of the first opening of the second light-shielding layer is less than the area of the second opening of the second light-shielding layer.
