An optoelectronic element includes an optoelectronic unit, a first metal layer, a second metal layer, a conductive layer and a transparent structure. The optoelectronic unit has a central line in a top view, a top surface, and a bottom surface. The second metal layer is formed on the top surface, and has an extension portion crossing over the central line and extending to the first metal layer. The conductive layer covers the first metal layer and the extension portion. The transparent structure covers the bottom surface without covering the top surface.
