Patent ID: 8519936

Claim:
A liquid crystal display device comprising: a first substrate and a second substrate 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 electrode and the other electrode; a control unit for controlling a voltage applied between the pair of electrodes; and a temperature detector, wherein the control unit 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 pair of electrodes when a temperature of the liquid crystal forming material detected by the temperature detector is in an isotropic phase temperature range, and the control unit 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 pair of electrodes when the temperature of the liquid crystal forming material detected by the temperature detector is in a nematic phase temperature range.
