<p>Disclosed is a liquid crystal display device which can perform suitable overshoot drive, even if a panel temperature is changed due to a change of the light emission luminance of a backlight. The liquid crystal display device is provided with: a liquid crystal panel (5); the backlight (10) which illuminates the liquid crystal panel (5); a temperature sensor (13) which detects the temperature in the device; an emphasis conversion section (2), which obtains, after the elapse of one vertical display period of the liquid crystal panel (5), an emphasis conversion parameter for making the transmissivity of the liquid crystal panel (5) reach the transmissivity specified by input image signals, and which outputs applying voltage signals for the liquid crystal panel (5) on the basis of the emphasis conversion parameter; and a main microcomputer (8), which corrects the panel temperature of the liquid crystal panel (5), said panel temperature corresponding to the temperature detected by means of the temperature sensor (13), on the basis of the changed light emission luminance when the light emission luminance of the backlight (10) is changed. The emphasis conversion section (2) variably controls the emphasis conversion parameter on the basis of the panel temperature corrected by means of the main microcomputer (8).</p> |
