<p>A light-emitting element (100) comprising: a light-transmitting substrate (110); a light-emitting layer arranged on the opposite side to the light extraction side, when using the light-transmitting substrate (110) as the reference therefor; and a diffraction grating layer (120) arranged on the opposite side to the light extraction side, when using the light-transmitting substrate (110) as the reference therefor. The diffraction grating layer (120) includes: a light-transmitting base section (121); and a plurality of structural bodies (122) that are periodically arranged in a direction intersecting the light-transmitting substrate (110) inside the base section (121), and which form a diffraction grating (123).</p> |
