## Abstract

Light-emitting devices are provided, the light-emitting devices include a light-emitting structure layer having a first conductive layer, a light-emitting layer and a second conductive layer sequentially stacked on a first of a substrate, a plurality of seed layer patterns formed apart each other in the first conductive layer; and a plurality of first electrodes formed through the substrate, wherein each of the first electrodes extends from a second side of the substrate to each of the seed layer patterns.

## Claims

### Claim 1

A light-emitting device, comprising:
a substrate including a via hole, wherein the via hole includes a first via hole penetrating through the substrate and a second via hole on the first via hole, and wherein a width of the second via hole is larger than a width of the first via hole;
an electrode filling the via hole;
a light-emitting element on the substrate;
phosphors on the light-emitting structure; and
a transparent resin having a dome shape surrounding the light-emitting element on the substrate.

### Claim 2 (depends on 1)
