Abstract
A light-emitting device includes a first substrate having a through-hole, a plurality of first light-emitting elements that are arranged on the first substrate, a second substrate that is attached to the first substrate to cover the through-hole of the first substrate, and a second light-emitting element arranged on the second substrate, and electrically connected to wiring of the first substrate.
Claims18
A light-emitting device, comprising:
- a first substrate including at least one through-hole;
- a plurality of first light-emitting elements that are arranged on the first substrate;
- at least one second substrate that is attached to the first substrate to cover the through-hole in the first substrate;
- and
- at least one second light-emitting element arranged on the second substrate, and electrically connected to wiring of the first substrate.
2 more elements
A method for manufacturing a light-emitting device, comprising the steps of:
- arranging a plurality of first light-emitting elements on a first substrate;
- removing a region on the first substrate at which a defective element is arranged, to thereby form a through-hole in the first substrate;
- attaching a second substrate, including at least one second light-emitting element arranged thereon, to the first substrate, to thereby cover the through-hole in the first substrate;
- and
- electrically connecting the second light-emitting element to wiring of the first substrate.
