Abstract:
A light-emitting device comprising a substrate and a light-emitting device section,wherein the light-emitting device section comprises: a light-emitting layer capable of emitting light by electroluminescence; a pair of electrode layers for applying an electric field to the light-emitting layer; alight-propagation section for propagating light-emitted in the light-emitting layer; an insulation layer disposed between the pair of electrode layers, having an opening formed in part, and capable of functioning as a current concentrating layer for specifying a region through which current to be supplied to the light-emitting layer flows through the opening; and an optical section for light propagated through the light-propagation section, wherein the optical section forms photonic band gaps in one dimension or two dimension and has a defect section which is set so that an energy level caused by defects is within a specific emission spectrum, and wherein the light emitted in the light-emitting layer is emitted with spontaneous emission in one dimension or two dimension inhibited by the photonic band gap.
