Abstract
The light emitting device includes a substrate, a light-emitting semiconductor structure, conductive pillars, an insulating layer, and first and second electrodes. The light-emitting semiconductor structure includes a first-type semiconductor layer, a light-emitting layer and a second-type semiconductor layer disposed on the substrate from bottom to top. The conductive pillars are disposed in the light-emitting semiconductor structure. The conductive pillars penetrates is in contact with the second-type semiconductor layer and electrically connected to the substrate. A first portion of the insulating layer is disposed between the first-type semiconductor layer and the substrate, and a second portion of the insulating layer electrically insulates the first-type semiconductor layer and the light emitting-layer from the conductive pillars. The first electrode is electrically connected to the first-type semiconductor layer and electrically insulated from the conductive pillars. The second electrode is electrically connected to the conductive pillar.
