- 12 - ABSTRACT OF THE DISCLOSURE An electrical display device, such as a liquid crystal display, for an instrument such as a speedometer, where two or more units of measurement may be required, comprises a first display area which extends along a line and which is formed to indicate a point along the line corresponding to the magnitude of a measured or selected value; a second display area adjacent the line adapted to indicate a length along the line upon which the point may be indicated; and two further display areas which are formed to be activated separately from the first and second display areas and from each other, and adapted to indicate a respective scale of markings against which the magnitude of the said value can be read, and said further display areas lying on the opposite side of the second display area from the first display area, and one of the further display areas including a part which forms an extension of the length of the line indicated by the second display area. By effectively increasing the length of the base line when the said one scale display area is activated, the indicia on the said one scale display area can be positioned between the indicia on the other scale display area, thus avoiding overlap of their electrodes and allowing the leads to the electrodes of both scale display areas to be positioned away from the leads to the electrodes for the first and second display areas.
