Light emitting apparatus and projector

A light emitting apparatus comprising:

• a laminated structure including a plurality of columnar section assemblies each formed of p columnar sections,
• wherein the p columnar sections each include a light emitting layer,
• when viewed in a lamination direction of the laminated structure, a ratio of a maximum width to a minimum width of the light emitting layer in each of q first columnar sections out of the p columnar sections is greater than the ratio of the light emitting layer in each of r second columnar sections out of the p columnar sections,
• the light emitting layer in each of the p columnar sections does not have a rotationally symmetrical shape,
• the parameter p is an integer greater than or equal to 2,
• the parameter q is an integer greater than or equal to 1 but smaller than p, and
• the parameter r is an integer that satisfies r=p−q,
• wherein the p columnar sections each include an n-type first semiconductor layer and a p-type second semiconductor layer,
• the light emitting layer is provided between the first semiconductor layer and the second semiconductor layer, and
• a carrier concentration in the second semiconductor layer in each of the q first columnar sections is higher than a carrier concentration in the second semiconductor layer in each of the r second columnar sections.
