Light emitting element

A light emitting element comprising:

• a first conductive type semiconductor layer;
• a mesa disposed on the first conductive type semiconductor layer and comprising an active layer and a second conductive type semiconductor layer disposed on the active layer;
• a first electrode electrically connected to the first conductive type semiconductor layer;
• a second conductive oxide electrode disposed on the mesa;
• and
• a second electrode disposed on the second conductive oxide electrode,
• wherein the first electrode comprises a first electrode pad and a first electrode extension extending from the first electrode pad,
• the first electrode extension comprising a metal electrode extension and a first conductive oxide electrode extension,
• the metal electrode extension extending from one side surface of the first electrode pad, and
• the first conductive oxide electrode extension extending from another side surface of the first electrode pad other than the one side surface of the first electrode pad,
• wherein the first conductive type semiconductor layer comprises a region in which a portion of an upper surface of the first conductive type semiconductor layer formed around the mesa is exposed, and the first conductive oxide electrode extension contacts the first conductive type semiconductor layer exposed around the mesa, and
• wherein the first conductive oxide electrode extension forms a closed curve surrounding the mesa.
