Abstract
In a liquid crystal display device, when the detected signal produced from a temperature sensor is not higher than an indicating disabling temperature of an LCD element, a controller supplies a high luminance signal to a dimmer circuit to raise a voltage to be applied to a light source, and on-off controls a driving signal within a much shorter time than the response time of the LCD element.
