Abstract
PURPOSE: To make it possible to keep normal functions sufficiently even in the cold northern district, by flowing a current from the external to one electrode, at least, of a liquid crystal display measuring instrument board and by using this electrode as a heating element to heat the liquid crystal layer.
CONSTITUTION: In the figure, lower electrode 2' of a liquid crystal element is used in common as a heating element for liquid crystal layer warming. In the example of the figure, a DC power source (voltage E) is used as the warming power source, and an AC power source of voltage Vs is used for the liquid crystal driving. When lower electrode 2' is used in common as the warming resistor also, heat generated by supplying to lower electrode 2' is propagated to lower substrate 1' first, and simultaneously, this heat is propagated to liquid crystal layer 4 through orientation film 3. Then, the element reaches a certain temperature, it can perform display operations, and the calorific value can be controlled by variable resistance R1 after the liquid crystal element reaches the temperature where it can operate normally.
