A light-emitting diode chip includes a first semiconductor layer, a second semiconductor layer and an active layer between them; an dielectric layer having a conductive through-hole array over the lower surface of the light-emitting epitaxial laminated layer; a metal conductive layer over the lower surface of the dielectric layer, which fills up the conductive through-hole, and forms ohmic contact with the light-emitting epitaxial laminated layer; a conductive substrate over the lower surface of the metal conductive layer for supporting the light-emitting epitaxial laminated layer; a first electrode comprising a bonding pad electrode and a finger-shape electrode over the upper surface of the light-emitting epitaxial laminated layer, wherein, a rotation angle is formed between the conductive through-hole array and the finger-shape electrode, which is selected to prevent a preferred number of conductive through-holes from being shielded by the bonding pad electrode and the finger-shape electrode.
