Semiconductor light-emitting element

A semiconductor light emitting device comprising:

• a light emitting structure including an n-type semiconductor layer, a p-type semiconductor layer, and an active layer interposed therebetween, and having a rectangular upper surface formed with first and second sides opposing one another and third and fourth sides opposing one another;
• a first electrode formed on an upper surface of the light emitting structure and connected to one of the n-type semiconductor layer and the p-type semiconductor layer;
• and
• a second electrode formed on the upper surface of the light emitting structure and connected to the other of the n-type semiconductor layer and the p-type semiconductor layer,
• wherein the first electrode comprises:
• a first electrode pad disposed in a central portion of the first side, a first branch electrode extending linearly from the first electrode pad toward the second side such that it is parallel to the third side;
• and
• second and third branch electrodes extending from the first electrode pad, bent toward the third and fourth sides, and extending toward the second side such that they are parallel to the first branch electrode and disposed on both sides of the first branch electrode, and
• the second electrode comprises a second electrode pad disposed in the corner between the second side and the third side;
• a third electrode pad disposed in the corner between the second side and the fourth side;
• a fourth branch electrode extending inwardly from the second electrode pad in a bent manner and extending linearly toward the first side between the first and second branch electrodes;
• a fifth branch electrode extending from the second electrode pad along the third side and disposed in outer side of the second branch electrode;
• a sixth branch electrode extending inwardly from the third electrode pad in a bent manner and extending linearly toward the first side between the first and third branch electrodes;
• and a seventh branch electrode extending from the third electrode pad along the fourth side and disposed in an outer side of the third branch electrode.
