ELECTRODE STRUCTURE OF LIGHT EMITTING DEVICE

PROBLEM TO BE SOLVED: To make a current path from a first to a second electrode equal in distance by an electrode structure formed with structures of hexagons regarding the electrode structure of a light emitting device. SOLUTION: In the electrode structure, the first electrode comprises a plurality of a first finger-like portion parallel mutually, one of a first connection, and at least one of a first contact; the first finger-like portion comprises a first and a second edges; the first edge is connected to the first connection; the first contact is inserted between the arbitrary first edge and first connection; the second electrode comprises a plurality of a second finger-like portion parallel mutually, one of the second connection, and at least one of the second contact; the second finger-like portion comprises a third and a fourth edges; the second finger-like portion locates between adjacent two of the first finger-like portions; the third edge is connected to the second connection; the second contact is inserted between the arbitrary third edge and second connection; the second electrode demarcates a plurality of hexagon unit among a plurality of second edge; the hexagon unit adjoins other hexagon units in four share sides; each two of the second finger-like portion and the second connection compose four share sides of the hexagon unit; and the second edge is extended into the center of a corresponding hexagon unit.
