Claim:
1. A liquid crystal display device comprising: a plurality of scan signal lines; a plurality of data signal lines; pixels provided at intersections of the plurality of scan signal lines and the plurality of data signal lines; a scan signal line drive circuit that selectively scans the scan signal lines; a data signal line drive circuit that supplies data signals via the respective plurality of data signal lines; a drive controller that controls the scan signal line drive circuit (i) to scan all of the plurality of scan signal lines during at least two driving frames contained in a first driving period and (ii) not to scan any of the plurality of scan signal lines during pausing frames in a pausing period which (i) is secured between the first driving period and a second driving period by which the first driving period is followed and (ii) is longer than each of the first and second driving periods; and a temperature sensor that measures a temperature inside the liquid crystal display device; wherein the scan signal line drive circuit outputs a vertical sync control signal, a period of which corresponds to one frame, the vertical sync control signal controlling a timing at which scanning of the scan signal lines is initiated; a total number of frames in the pausing period is larger than a total number of frames in the first driving period; the first and second driving periods each contain driving frames which correspond to a longest response time required for a transition of the pixels due to the temperature inside the liquid crystal display device from a first gradation to a second gradation which is different from the first gradation; the drive controller controls a number of the driving frames in accordance with the temperature inside the liquid crystal display device; and the number of the driving frames is increased as the temperature inside the liquid crystal display device decreases.
