Abstract
An electroluminescent panel comprising a pair of electrodes having sandwiched therebetween a multi-layer comprising an insulating layer in contact with one of said electrodes, an electroluminescent layer and an intermediate layer formed from a conductive material which is in intimate contact with the electroluminescent layer but is out of contact with both of the electrodes. Due to the provision of the intermediate layer, the brightness of the electroluminescent panel can be kept high for a long time.
