Light emitting element

A light emitting element, comprising:

• a substrate, wherein a surface of the substrate has a plurality of grooves;
• a layered structure that includes:
• a first light reflecting layer that includes a first plurality of thin films;
• a light emitting structure;
• and
• a second light reflecting layer that includes a second plurality of thin films,
• wherein the light emitting structure is between the first light reflecting layer and the swecond light reflecting layer, and
• the light emitting structure includes:
• a first compound semiconductor layer on the first light reflecting layer and the surface of the substrate;
• an active layer on the first compound semiconductor layer;
• and
• a second compound semiconductor layer on the active layer;
• an intermediate layer between the second compound semiconductor layer and the second light reflecting layer;
• and
• an electrode between the intermediate layer and the second compound semiconductor layer, wherein a first surface of the intermediate layer faces the electrode, a second surface of the intermediate layer is in contact with the second light reflecting layer, and a value of a surface roughness of the second surface of the intermediate layer is less than a value of a surface roughness of the first surface of the intermediate layer.
