US 12,604,633 B2 · Display apparatus and method of manufacturing the same

Abstract

A display apparatus includes a substrate. A light-emitting element is disposed on the substrate. The light-emitting element emits light. A photodetector is disposed on the substrate. The photodetector detects light. A light-blocking layer includes a first hole and a second hole. The first hole is disposed above the light-emitting element. The second hole is disposed above the photodetector. A first color filter is disposed to cover the first hole. A second color filter is disposed to cover the second hole. A third color filter is arranged to overlap a portion of the second hole.
