Abstract

The invention relates to a display module (11) comprising a backlit liquid crystal cell (17) like one located, in particular, in the operating panel of a large household appliance. A particularly economical design is achieved when the height of module (11) is determined by the tensioning of a frame (27), which surrounds the liquid crystal cell (17) and the light guide plate (19), against a circuit support (12) whose surface is provided in the form of a reflector surface (20) upon which the light guide plate (19) rests. The circuit support (12) is preferably manufactured using MID (molded interconnect device) technology in the form of an injection molded part with integrated conductor paths (15) and a molded holding fixture (22) provided for holding the light guide plate (19). The frame (27), which can be slipped over the sandwich structure consisting of the light guide plate (19) and liquid crystal cell (17), is coupled via a film hinge (41) to the injection molded part while forming one piece. The fastening between the frame (27) and the circuit support (12) is effected by elastically arresting barbs (34) with the passing through of positioning posts (43) whose free faces are hot-pressed in order to fix the position.
