Abstract

A light emitting apparatus includes a laminated structure including a plurality of columnar section assemblies each formed of p columnar sections. The p columnar sections each include a light emitting layer. When viewed in the lamination direction of the laminated structure, the ratio of the maximum width to the 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. The parameter r is an integer that satisfies r=p−q.
