摘要： A light emitting apparatus of the present invention includes: an EL emitting unit including at least a light emitting layer which generates an EL light; and a pair of light blocking layers arranged such that they sandwich the light emitting layer so that the layers block the EL light generated in the light emitting layer and that the EL light is radiated only from the end of the light emitting layer; and a light emitting unit which optically guides the EL light radiated from the end of the light emitting layer and emits a light having a wavelength equal to or different from that of the EL light. The EL light is emitted only from the end of the light emitting layer since the EL light generated in the light emitting layer is blocked by the pair of light blocking layers. This emitted EL light is optically guided by the light emitting unit and emitted as it is or a light having a different wavelength from the EL light.
