In an illuminating system for a display screen device, there is at least one lamp located in an accessory unit (2). This lamp (3) is connected via a light guide (4) with a display field (6) of the display screen device (1). This arrangement serves for illumination of the display field (6) by transmitted light. In order that the display screen device (1) can be removed without the lamp (3), the light guides (4) at the transition between accessory unit (2) and display screen device (1) are interrupted and have a light output surface (7) of the accessory unit and a light input surface (8) of the screen device.
