Abstract
In a display control circuit () of a display device, an image pattern detection portion () detects whether an image is an anti-flicker pattern or not, and when it is an anti-flicker pattern, a backlight source is driven (typically, such that its luminance changes in the opposite phase relative to luminance changes that would occur), on the basis of predicted values, which are predetermined so as to compensate for the luminance changes that would occur. Moreover, the backlight is not turned on during the scanning period. As a result, flicker due to current leakage, etc., can be reduced or eliminated in a display device for which a scanning period and a scan stop period are set.
