Patent ID: 11380820

Abstract:
In a light emitting device, a columnar part includes a first semiconductor layer, a second semiconductor layer different in conductivity type from the first semiconductor layer, and a light emitting layer disposed between the first semiconductor layer and the second semiconductor layer, the first semiconductor layer is disposed between the substrate and the light emitting layer, the light emitting layer includes a first layer, and a second layer larger in bandgap than the first layer, the first semiconductor layer has a facet plane, the first layer has a facet plane, the facet plane of the first semiconductor layer is provided with the first layer, and θ2>θ1, in which θ1 is a tilt angle of the facet plane of the first semiconductor layer with respect to a surface of the substrate provided with the laminated structure, and θ2 is a tilt angle of the facet plane of the first layer provided to the facet plane of the first semiconductor layer with respect to the surface of the substrate.
