Abstract
In an electroluminescence light arrangement comprising a carrier substrate (1) of an electrically insulating material on which there is an electrically conductive layer from which there are formed at least two conductor track regions which are electrically insulated from each other and which form a first electrode (3) and a second electrode (5) and are covered over by a pigment layer (14) whose doped pigments light when an ac voltage is applied to the two electrodes, to increase the light brightness it is provided that at least in a portion of its surface the pigment layer (14) is covered over by a thin transparent electrically conductive cover layer (16) to which in operation no additional voltage is applied from the exterior.
