LIGHT-EMITTING DEVICE

摘要

Disclosed is a light-emitting device comprising a pair of electrodes at least one of which is transparent or semi-transparent, and a light-emitting layer arranged between the pair of electrodes. The light-emitting layer contains luminescent particles dispersed therein, and conductive nanoparticles are interposed at the interface between the light-emitting layer and one of the electrodes. Also disclosed is another light-emitting device comprising a pair of electrodes at least one of which is transparent or semi-transparent, and a light-emitting layer arranged between the pair of electrodes. In this light-emitting device, the light-emitting layer contains luminescent particles dispersed therein, and at least one of the pair of electrodes is provided with a brush-like electrode projecting towards the light-emitting layer. The brush-like electrode may be formed on the positive-side electrode, and the brush-like electrode formed on the positive-side electrode may preferably have a work function of not less than 4.5 eV.
