Abstract
According to one embodiment, a light emitting device includes a first base section, a light emitting section, and a first wiring section. The light emitting section is embedded on a first surface side of the first base section. The light emitting section includes a light emitting element. The first wiring section is provided on the first surface of the first base section. The first wiring section is connected to the light emitting element.
Claims17
A light emitting device comprising:
- a first base section;
- a plurality of light emitting sections embedded on a first surface side of the first base section, the plurality of light emitting sections being provided side by side in a first direction and a second direction perpendicular to the first direction, wherein:
- each of the light emitting sections includes a light emitting element, a first electrode wiring, a second electrode wiring, a first pillar section, a second pillar section, and a sealing section;
- the first pillar section is connected to the light emitting element via the first electrode wiring;
- the second pillar section is connected to the light emitting element via the second electrode wiring;
- the sealing section is provided so as to cover the first electrode wiring, the first pillar section, the second electrode wiring, and the second pillar section;
- and
- an end surface of the first pillar section and an end surface of the second pillar section are exposed from the sealing section;
- and
- a first wiring section provided on the first surface of the first base section,
- wherein:
- the first wiring section is connected to and covers an entirety of a top planar region between the first pillar section of one of the light emitting sections and the second pillar section of an adjacent one of the light emitting sections in the first direction;
- the first wiring section is connected to and covers an entirety of a top planar region between the first pillar section of one of the light emitting sections and the first pillar section of an adjacent one of the light emitting sections in the second direction;
- the first wiring section is connected to and covers an entirety of a top planar region between the second pillar section of one of the light emitting sections and the second pillar section of an adjacent one of the light emitting sections in the second direction;
- and
- the first wiring section is planar.
