Disclosed is a light-emitting device (10) comprising luminescent particles (14) and a pair of electrodes (12, 16) for injecting an electric current into the luminescent particles (14). An inorganic hole transporting material (15) is arranged between the electrodes (12, 16), and the luminescent particles (14) are dispersed in the inorganic hole transporting material (15). A conductive fine particle may be adhered to at least a part of the surfaces of the luminescent particles (14) for the purpose of obtaining higher luminance and higher efficiency. L'invention concerne un dispositif (10) émettant de la lumière comprenant des particules luminescentes (14) et une paire d'électrodes (12, 16) pour l'injection d'un courant électrique dans les particules luminescentes (14). Une matière inorganique (15) de transport de trous est disposée entre les électrodes (12, 16) et les particules luminescentes (14) sont dispersées dans la matière inorganique (15) de transport de trous. De fines particules conductrices peuvent être collées à au moins une partie des surfaces des particules luminescentes (14) dans le but d'obtenir une luminance et un rendement supérieurs.
