摘要： A light emitting apparatus according to the present disclosure includes an organic light emitting element (100) including a reflection surface (S2), a first electrode (2), an organic layer (3) including a light emitting layer (31), a second electrode (4), and a light extraction structure (10). The light emitting layer (31) contains a first light emitting material. A wavelength included in a peak wavelength range of a PL spectrum of the first light emitting material is assumed as a first wavelength λ1. An optical distance (Lb) between the light emitting layer (31) and the reflection surface (S2) is a value with which rays of light with the first wavelength (λ1), traveling in a first direction (D1) and a second direction (D2) that intersect with a normal direction of a principal surface (S1) of the substrate (1), both are intensified. When the intensified rays of light respectively reach a first inclined portion (21a) and a second inclined portion (21b) of the light extraction structure (10), the rays of light respectively are emitted in a third direction (D3) and a fourth direction (D4) that are directions substantially perpendicular to the principal surface (S1) of the substrate (1).
