Abstract
A light-emitting diode structure comprising: a substrate; a light-emitting semiconductor stack on the substrate, wherein the light-emitting semiconductor stack comprises a first semiconductor layer, a second semiconductor layer with different polarity from the first semiconductor layer, and a light-emitting layer between the first semiconductor layer and the second semiconductor layer; a first electrical pad on the substrate, wherein the first electrical pad is apart from the light-emitting semiconductor stack and electrically connects to the first semiconductor layer; and a second electrical pad on the substrate, wherein the second electrical pad is apart from the light-emitting semiconductor stack and electrically connects to the second semiconductor layer, wherein the first electrical pad and the second electrical pad are not higher than the light-emitting semiconductor stack.
