Patent ID: 8530913

Claim:
A light emitting device comprising: a light emitting layer capable of emitting emission light; a first electrode; a first layer provided between the light emitting layer and the first electrode, having a first impurity concentration of a first conductivity type, and allowing a carrier injected from the first electrode to be spread in an in-plane direction of the light emitting layer; a second layer provided between the first layer and the first electrode, having a second impurity concentration of the first conductivity type higher than the first impurity concentration, and including a first surface and a second surface on an opposite side of the first surface, the first surface being with the first layer, the second surface having a formation region and a non-formation region of the first electrode, the formation region of the first electrode not including convex structures, the non-formation region of the first electrode including convex structures with an average pitch not more than a wavelength of the emission light; and a cladding layer provided between the first layer and the light emitting layer and having an impurity concentration of the first conductivity type, the convex structures being mesh-like or island-like and having flat regions at an upper surface and bottom portions around the flat regions, the average pitch being an average value of distances between the bottom portions of mesh-like convex structures, or an average value of distances between the flat regions of island-like convex structures, and the bottom portions not reaching the first surface.
