Light emitting diode chip having electrode pad

A light emitting diode device comprising:

• is a substrate having first and second edge that oppose to each other;
• a light emitting structure including a first conductive-type semiconductor layer formed over the substrate, a second conductive-type semiconductor layer formed over the first conductive-type semiconductor layer;
• and an active layer interposed between the first conductive-type semiconductor layer and the second conductive-type semiconductor layer;
• a first electrode pad formed over the light emitting structure around the first edge of the substrate;
• a first electrode extension extending from the first electrode pad;
• a second electrode pad formed over the light emitting structure around the second edge of the substrate;
• and
• a second electrode extension extending from the second electrode pad,
• wherein along the first electrode extension, first openings are located spaced apart from one another to connect the first electrode extension to the first conductive-type semiconductor layer, and
• along the second electrode extension, second openings are located spaced apart from one another to cause a current block in the openings and a current crowd between the openings.
