Abstract
A display module has a back-lit liquid crystal cell and is used in particular in an operating panel of a large domestic appliance. A particularly inexpensive structure is afforded in which the height-wise dimension of the module is affected by bracing a frame that mounts the liquid crystal cell and a light-guide panel under it against a circuit carrier whose surface on which the light-guide panel rests is in the form of a reflector surface. The circuit carrier has integrated conductor tracks and a receiving device formed therein for the light-guide panel. The frame can be fitted over the sandwich structure of the light-guide panel and the liquid crystal cell. Fixing as between the frame and the circuit carrier is effected by resiliently latching barb hook members, and with through-engagement of positioning studs or pillars. The free ends of which are subjected to hot peening for fixing the position thereof.
