A device, particularly for the instrument panel of a motor vehicle, comprises a liquid crystal display module comprising a multiplicity of parallel inputs connected via a multiplicity of control lines to a multiplicity of outputs of a control module supplied by an electrical power supply. The output of the display module and the electrical power supply are connected to an electrical ground. A branch line has, on the one hand, an input connected to the electrical power supply and an output connected directly to the output of the display module, and has, on the other hand, an impedance considerably lower than the corresponding impedance of each pair formed by a control line and the output of the associated control module. The device is thus protected against electrostatic discharges.
