Abstract
An electrode structure for a light-emitting element includes a first electrode and a second electrode. The first electrode has a plurality of first fingers paralleling with each other, a first connective part, and at least a first contact part. Each first finger has a first end and a second end. Pluralities of first ends connect to the first connective part. The first contact part interposes between any first end and the first connective part. The second electrode has a plurality of second fingers paralleling with each other, a second connective part, and at least a second contact part. Each second finger has a third end and a fourth end, and any second finger is between and parallels to any two first fingers. Pluralities of third ends connect to the second connective part. The second contact part interposes between any third end and the second connective part. The second electrode defines a plurality of hexagonal units among a plurality of second ends. Each hexagonal unit shares its four sides to its adjacent hexagonal units, and the four sides include two of the second fingers and the second connective part. Each second end extends to the center of each hexagonal unit.
