In the disclosed display, the symbol segments of a passive cell, such as a liquid crystal cell, are each connected to one of two leads through an elastic connector layer having mutually insulated conductors running through the layer transverse thereto. According to an embodiment of the invention, the leads are on a printed circuit board and a control bus connects one of the leads to a control unit that operates the cell and a second bus connects the other of each of the leads to a monitor unit that compares the potential at each segment with the potential at the control unit. This checks the connections between the control unit and each segment.
