Abstract: The present display device combines a liquid crystal display panel with a transparent dial for example having a polar coordinate system on which the information shown by the panel may be displayed with regard to its value and location or angular position. This type of display is especially suitable for displaying unbalance informations of a body to be balanced. In the present process an unbalance representing signals are separated into horizontal and vertical components, which are then supplied respectively to the row and column electrodes of said liquid crystal display device. The dial itself may also be constituted as a liquid crystal display panel. The row and column electrodes may be provided in several sets for simultaneously displaying several unbalance informations, for example, relating to different planes in a body to be balanced.
