Abstract
The present invention is related to a light emitting device with an insulating layer, which comprises a transparent substrate, a first light emitting unit, a second light emitting unit, an insulating layer and a conducting layer. The first light emitting unit and the second light emitting unit are set up on the transparent substrate, wherein the second light emitting unit has an appearance of a stair structure. The insulating layer is set between the first and the second light emitting units. The conducting layer is on the insulating layer in order to conduct the first and the second light emitting units. Because of the appearance of the stair structure of the second light emitting unit, improving the cladding efficiency of the insulating layer, further improving the insulating efficiency of the insulating layer and avoiding the insulating layer loosing and the leakage between the first and the second light emitting units.
