| 摘要 |
A controller display board (15) is disclosed which has an electroluminescent element (1) for overall illumination of operating regions such as, for example, a thin-film switch (2) and of the controller display board (15) as well as relatively small light-emitting elements (27) for partial illumination of a display region of a switch (17, 18) which has been operated, and a wiring board (26) for supplying the respective light-emitting element (27) with electric current. The controller display board (15) is constructed from an electroluminescent element (1) and a thin-film switch (2) which is located above said element (1) and is formed from two light-conducting, insulating flat elements (2b) and from a pair of electrodes (2c) which are arranged on the insulating flat elements (2b), the light-emitting element (27) being arranged on the operating side of the thin-film switch (2) and having an illumination area which is smaller than the electroluminescent element (1), and a wiring board (26) being arranged between the electroluminescent element (1) and the thin-film switch (2). <IMAGE>
