A invention relates to a self-illuminating LCD display device containing an LCD module with a first polarizer layer ( ), a first transparent substrate ( ), a first transparent electrode layer ( ), a liquid crystal layer ( ), a second transparent electrode layer ( ), a second transparent substrate ( ) and a second polarizer layer ( ), and containing an LED module for illuminating the LCD module, having a third transparent electrode layer ( ), a layer ( ) containing organic light-emitting materials, a fourth electrode layer ( ) and a substrate ( ) as well as, if appropriate, further layers contained between the third and fourth electrode layer. A self-illuminating LCD display device according to the invention which is particularly easy to produce is distinguished in that one of the polarizer layers or, when the polarizer layer is arranged between the substrate and electrode layer, the substrate carrying it, is the substrate for the third transparent electrode layer.

Self-illuminating LCD display device

A display unit, in particular in a vehicle, has a display (,.) which can be transilluminated by a transilluminating device (,) in a prescribed direction. Light launched from a light source (,) into an optical conductor (,) is aligned by a first optical element (,) and deflected into a prescribed direction by a second, displaceably arranged optical element (,). As a result, an image on the display (,) is to be detected exclusively from a viewing angle region in which the display (,) is transilluminated.
