MULTILAYER ELEMENT COMPRISING A FUNCTIONAL LAYER HAVING ELECTRICALLY VARIABLE OPTICAL PROPERTIES

摘要

A multilayer element (1) has a first transparent surface electrode (3), an electroluminescence luminous element (4) and a planar rear electrode (6). The first transparent surface electrode (3) projects laterally beyond the electroluminescence luminous element (4) and the rear electrode (6) and, in a region (13) projecting laterally beyond the rear electrode (6), is provided with a connection element (17) for feeding in voltage. In order to achieve an invisible voltage feed particularly in the edge regions of the electroluminescence luminous element (4), a second transparent surface electrode (8) is provided, which is connected by means of a transparent dielectric adhesive layer (7) firstly to the rear electrode (6) and, in a region (13) projecting beyond the rear electrode (6), secondly to the first transparent surface electrode (3). In this case, a contact element (22) that penetrates through the dielectric transparent adhesive layer (7) is arranged between the rear electrode (6) and the second transparent surface electrode (8), said contact element connecting the rear electrode (6) and the second transparent surface electrode (8) to one another at least indirectly.
