Abstract
On a through-electrode (7) formed by filling a conductive material into a though hole of a substrate, nano-metal particles are adhered to form a connection electrode (9). An LED element (3) is electrically connected to the through-electrode (7) via the connection electrode (9). The nano-metal particles can be applied into a desired shape by an inkjet method or a dispenser method, and hence a light emitting device (1) having high electrical connection reliability is realized at low cost.
Claims11
A light emitting device, comprising:
- a substrate including a through-electrode formed therein;
- a light emitting element mounted on the substrate and electrically connected to the through-electrode;
- and
- a connection electrode provided on a surface of the through-electrode exposed from the substrate, the connection electrode being formed of nano-metal particles,
- wherein the light emitting element and the through-electrode are electrically connected to each other via the connection electrode.
