Abstract
A light-emitting diode (LED) chip () comprises a substrate (), an epitaxial structure (), a transparent conductive layer (), a passivation protective layer (), and at least one electrode (). The epitaxial structure () is disposed on the substrate (). The transparent conductive layer () is disposed on the epitaxial structure (). The transparent conductive layer () defines one or more first through holes () that extend through the transparent conductive layer (). The passivation protective layer () is disposed on the transparent conductive layer (). The passivation protective layer () defines one or more second through holes () that extend through the passivation protective layer (). The electrode () is disposed on the passivation protective layer (). The electrode () electrically connects the transparent conductive layer () through the one or more second through holes ().
