Disclosed is a light emitting device including a pair of electrodes at least one of which is transparent or semi-transparent, and a phosphor layer arranged between the pair of electrodes. The phosphor layer contains phosphor particles dispersed therein, and conductive nano particles are interposed at the interface between the phosphor layer and one of the electrodes. Also disclosed is another light emitting device including a pair of electrodes at least one of which is transparent or semi-transparent, and a phosphor layer arranged between the pair of electrodes. In this light emitting device, the phosphor layer contains phosphor particles dispersed therein, and at least one of the pair of electrodes is provided with a brush-like electrode projecting towards the phosphor layer. The brush-like electrode may be provided on the electrode on the positive electrode side, and the brush-like electrode provided on the electrode on the positive electrode side may preferably have a work function of 4.5 eV or more.
