Abstract
A liquid crystal display device includes: first and second substrates between which a liquid crystal forming material is sandwiched and which are disposed to be opposite to each other; a pair of electrodes including one and the other electrodes; a control means for controlling a voltage applied between the electrodes; and a temperature detector. The control means applies a voltage, by which a change of light transmittance occurs based on an induction and disappearance phenomenon of a nematic phase in the liquid crystal forming material, between the electrodes when a temperature of the liquid crystal forming material is in an isotropic phase temperature range, and the control means applies a voltage, by which a change of light transmittance occurs based on a change of orientation of directors of the liquid crystal forming material, between the electrodes when the temperature of the liquid crystal forming material is in a nematic phase temperature range.
