Abstract
An LED array having N light-emitting diode units (N≧3) comprises a permanent substrate, a bonding layer on the permanent substrate, a second conductive layer on the bonding layer, a second isolation layer on the second conductive layer, a crossover metal layer on the second isolation layer, a first isolation layer on the crossover metal layer, a conductive connecting layer on the first isolation layer, an epitaxial structure on the conductive connecting layer, and a first electrode layer on the epitaxial structure. The light-emitting diode units are electrically connected with each other by the crossover metal layer.
