Title: LIGHT EMITTING DEVICE AND PROJECTOR
Abstract:
Provided is a light emitting device capable of suppressing a leak current. The light emitting device includes: a base body; a first semiconductor layer having a first conductivity type; a second semiconductor layer having a second conductivity type that is different from the first conductivity type; a light emitting layer, which is provided between the first semiconductor layer and the second semiconductor layer, and which is capable of emitting light when a current is injected; and a third semiconductor layer, which is provided between the base body and the first semiconductor layer, and which has the second conductivity type. The first semiconductor layer is provided between the third semiconductor layer and the light emitting layer, and the third semiconductor layer has a recessed and projecting structure.
