An electroluminescent device and a method for making it are disclosed. The device has a transparent substrate (1), a transparent conductive layer (2) placed on the back surface of said transparent substrate (1), a luminescent layer (8) comprising luminescent particles (7) and a matrix resin and being placed on the back surface of said transparent conductive layer (2), and a rear electrode (6) placed on the back surface of said luminescent layer (8), wherein said luminescent layer (8) has a transparent support layer (3) comprising a matrix resin and being placed on the side of said transparent conductive layer (2), an insulating layer (5) comprising an insulating material and being placed on the side of said rear electrode, and a luminescent particle layer (4) consisting essentially of particles which comprise luminescent particle (7) and are embedded in both said support layer (3) and said insulating layer (5).

L'invention a trait à un dispositif électroluminescent et à son procédé de production. Ce dispositif possède un substrat transparent (1), une couche transparente conductrice (2), déposée sur la face arrière du substrat transparent (1), une couche luminescente (8), comportant des particules luminescentes (7) ainsi qu'une résine d'enrobage, déposée sur la face arrière de la couche transparente conductrice (2), et une électrode arrière (6) placée sur la face arrière de la couche luminescente (8). La couche luminescente (8) possède une couche transparente de support (3), comportant une résine d'enrobage, déposée sur le coté de la couche transparente conductrice (2), une couche isolante (5), comportant une couche de particules luminescentes (4) principalement constituée de particules comprenant une particule luminescente (7), ces particules étant noyées à la fois dans la couche de support (3) et dans la couche isolante (5).
