Abstract

PURPOSE: To enable display without using converter or the like, by varying the lighting area with the voltage generated depending on the physical quantity of the object being measured by utilizing the threshold value of liquid crystal cell.
CONSTITUTION: The interval of electrodes 2, 3 to apply voltage to a liquid crystal layer 4 located between an upper glass 7 and a lower glass 8 is varied depending on the quantity of display. Since the threshold value of the liquid crystal varies with the positions of the electrodes 2, 3, the length l of the lighting area 5 of the liquid crystal is designed to change according to the voltage applied between the electrodes. Or, in other method, with the interval set constant, the electrode may be divided into a plurality, and the input voltage may be divided and applied to each electrode according to a certain rule.
