英文摘要	A light-emitting device (1000) includes a light-emitting device section (100) and a waveguide section (200) which transmits light from the light-emitting device section, and the light-emitting device section and the waveguide section are integrally formed on a substrate (10). The light-emitting device section (100) has a transparent anode (20) which form up a light-propagation section and an optical section (12) formed in part of the anode (20) which are formed on the substrate (10), a first dielectric multilayer film (11a), an insulation layer (16) having an opening (16a) facing the optical section (12), a light-emitting layer (14), at least part of which is formed in the opening (16a) of the insulation layer (16), a cathode (22), and a second dielectric multilayer film (11b). The optical section (12) forms a one-dimensional photonic band gap and has a defect section which is set so that the energy level caused by defects is within a specific emission spectrum. The light-emitting device can emit light excelling in wavelength selectivity and having directivity, and can be applied not only to displays but also to optical communications and the like.
