Abstract
An LED device includes an epitaxial layered structure that includes a first semiconductor layer, a light emitting layer and a second semiconductor layer, first and second electrodes that are disposed on the epitaxial layered structure, and an insulating structure. The first electrode includes a first body portion and a first extending portion connected together. The first extending portion includes a first part and multiple second parts. A projection of the first part on the first semiconductor layer does not overlap a projection of the insulating structure on the first semiconductor layer. The first part has a first sub-part and multiple second sub-parts. A projection of the first sub-part on the first semiconductor layer has a first length, and a projection of each of the second sub-parts on the first semiconductor layer independently has a second length measured in the same direction. The first length is greater than the second length.
