Light emitting diodes with spreading and improving light emitting area

A light emitting diode device comprising:

• a substrate;
• a first semiconductor structure on said substrate, said first semiconductor structure having a first conductivity, and consisted of a first portion and a second portion;
• a light emitting structure on said first portion;
• a first contact structure with said first conductivity on said second portion, said first contact structure having a first shape;
• a second semiconductor structure on said light emitting structure, said second semiconductor having a second conductivity opposite to said first conductivity;
• a transparent contact on said second semiconductor structure, said transparent contact having a plurality of hollow patterns enabled to light emitted therethrough, said transparent contact having a second shape;
• and
• a second contact structure with said second conductivity on said transparent contact and electrically connected to said first contact structure, wherein said second contact structure with a third shape associated with said transparent contact with said second shape and said first contact structure with said first shape provides a plurality of current paths with substantially equal distances between said first contact structure and said second contact structure.
