An electroluminescent device and a method for producing the electroluminescent device are described. The device is formed from a layered structure comprising a hole-injection electrode layer for injecting holes into an electroluminescent material, an electron-injection electrode layer for injecting electrons into an electroluminescent material and a dielectric layer interposed between the hole-injecting and electron-injecting electrode layers. A cavity extends through at least the dielectric layer and one of the electrode layers and has an interior cavity surface comprising a hole-injection electrode region, an electron-injection electrode region and a dielectric region. An electroluminescent coating material is applied to the interior cavity surface in order to electrically contact the hole-injection and electron-injection electrode regions of the interior cavity surface. |
