Light-emitting device

A light-emitting device, comprising:

• a light-emitting stack comprising a first side, a second side opposite to the first side, a third side connected to the first side and the second side, and a fourth side opposite to the third side, wherein the first side and the second side are shorter than the third side and the fourth side;
• a first electrode pad formed on the light-emitting stack;
• a second electrode pad formed on the light-emitting stack;
• and
• a first extension electrode comprising a first section extended from the first electrode pad in a direction away from the third side, and a second section connected to the first section and extended to the second side;
• wherein a distance between the first electrode pad and the third side is smaller than a distance between the second electrode pad and the third side.

A light-emitting device, comprising:

• a light-emitting stack comprising an lower semiconductor layer comprising a first portion and a second portion, an active layer disposed on the first portion of the lower semiconductor layer, and an upper semiconductor layer disposed on the active layer, wherein the second portion is exposed by the active layer, wherein the light-emitting stack comprises a first side, a second side opposite to the first side, a third side connected to the first side and the second side, and a fourth side opposite to the third side;
• a first electrode pad disposed on the second portion of the lower semiconductor layer and adjacent to the third side;
• a second electrode pad disposed on the upper semiconductor layer;
• and
• a first extension electrode comprising a first section extended from the first electrode pad in a direction away from the third side, and a second section connected to the first section and extended to the second side;
• wherein a distance between the first electrode pad and the third side is smaller than a distance between the second electrode pad and the fourth side.
