摘要:
A light-emitting device includes a first compound semiconductor layer, an active layer, and a second compound semiconductor layer; a second electrode formed on the second compound semiconductor layer; an insulating layer covering the second electrode; a first opening provided to pass through the insulating layer, the second electrode, the second compound semiconductor layer, and the active layer; a second opening provided to pass through the insulating layer; a first electrode formed on an exposed portion of the first compound semiconductor layer at the bottom of the first opening; a first electrode extension extending from the first electrode to the insulating layer through the first opening and a first pad portion including a portion of the first electrode extension on the insulating layer; and a second pad portion connected to an exposed portion of the second electrode at the bottom of the second opening.
