Light-emitting element, projection-type display device and light source device

摘要

Source layer (4), I have a substrate (10), and the electron transport layer (11) of the hole transport layer pair disposed on a substrate (10) and (13). Directivity control layer (5), the plasmon excitation layer having a plasma frequency higher than the frequency of light emitted a light source layer (4) is laminated on the opposite side of the substrate (4) Light source layer (10) side (15) and, with wavenumber vector conversion layer which emits by converting the output angle of a given incident light plasmon excitation layer (15) laminated on plasmon excitation layer (15) and (17). (15) is sandwiched between the low dielectric constant layer (14) high dielectric constant layer (16) layer plasmon excitation.
