  • Publication number: 20220328734
    Abstract: A light-emitting device comprises a light-emitting element, a covering structure, a quantum dot material block, and an adhesive structure is disclosed. The covering structure has a depressed part. The quantum dot material block is filled into the depressed part and enclosed by the light-emitting element and the covering structure. The light-emitting element, the covering structure, and the quantum dot material block are bonded together through the adhesive structure. Since the quantum dot material block is enclosed by the covering structure and the light-emitting element, the outer moisture and oxygen are blocked by the covering structure and the light-emitting element from the quantum dot material block, the decreasing emitting efficiency of the quantum dot material is further alleviated.
