There is provided a liquid crystal comprising a liquid crystal panel with a memory effect ( 2 ) sandwiching liquid crystals of a memory effect, a driving circuit ( 10 ) outputs driving voltage for driving the liquid crystal panel with a memory effect ( 2 ) and a temperature sensor for detecting an ambient temperature, wherein the driving circuit ( 10 ) includes a control circuit ( 11 ) for varying a driving voltage. The control circuit has a first temperature compensation range where the driving voltage is increased from a high temperature side toward a lower temperature side according to temperature information detected by the temperature sensor ( 3 ), and a second temperature compensation range where the driving voltage is rendered in a maximum value at a predetermined temperature, or rendered substantially equal to, or smaller than the maximum value on a side of the boundary, lower than the predetermined temperature.
