Title:
LIGHT-EMITTING DEVICE AND DISTANCE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/079934
Kind Code:
A1
Abstract:
[Problem] To prevent separation of the bonded portions of a first substrate having a light-emitting element and a second substrate, such as an LDD substrate. [Solution] A light-emitting device comprising a first substrate having a light-emitting element, and a second substrate bonded to a surface side of the light-emitting element opposite to a light-emitting surface thereof, wherein the first substrate comprises: a first conductive layer laminated on the opposite surface side of the light-emitting element; a second conductive layer laminated on the first conductive layer to reflect light output from the light-emitting element on the opposite surface side; a third conductive layer laminated on the second conductive layer and bonded to the second substrate with a bonding member therebetween; and an insulating layer laminated on the third conductive layer so as to cover at least ends of the second conductive layer and the third conductive layer laminated together.
