摘要： The present invention includes light source layer (4) and directivity controlling layer (5) into which light emitted from light source layer (4) enters. Light source layer (4) has a pair of hole transport layer (11) and electron transport layer (13) formed on substrate (10). Directivity controlling layer (5) has plasmon excitation layer (15) that is laminated on non-substrate (10) side of light source layer (4) and that has a higher plasma frequency than light emitted from light source layer (4) and wave number vector conversion layer (17) that converts surface plasmons that are generated in plasmon excitation layer (15) into light having a predetermined emission angle and emits the light having the predetermined emission angle. Plasmon excitation layer (15) is sandwiched between two layers having dielectricity. The effective dielectric constant of the incident side portion including the entire structure laminated on light source layer (4) side of plasmon excitation layer (15) is greater than that of the emission side portion including the entire structure laminated on wave number vector conversion layer (17) side of plasmon excitation layer (15) and a medium that contacts wave number vector conversion layer (17).
