Abstract:
1. A semiconductor light emitting device comprising: a p-type semiconductor layer including a nitride semiconductor and having a first major surface; an n-type semiconductor layer including a nitride semiconductor and having a second major surface; a light emitting layer provided between the n-type semiconductor layer and the p-type semiconductor layer, the first major surface being on a side of the p-type semiconductor layer opposite to the light emitting layer, the second major surface being on a side of the n-type semiconductor layer opposite to the light emitting layer; a p-side electrode contacting a first region of the p-type semiconductor layer on the first major surface; an n-side electrode contacting a second region of the n-type semiconductor layer on the second major surface; and a high resistance region provided on the first major surface of the p-type semiconductor layer, the high resistance region having a part outside the first region in a plan view along a direction from the p-type semiconductor layer to the n-type semiconductor layer, and an electrical resistance between the high resistance region and the p-type semiconductor layer being higher than an electrical resistance between the p-side electrode and the p-type semiconductor layer in the first region, the n-side electrode being provided outside and around the first region in the plan view.
