Abstract
Provided is a liquid crystal display device capable of improving motion blur and preventing excessive current flow into a light source with a desired balance in a structure where the light intensity of a backlight device is properly changed in conjunction with the ambient illuminance. If the ambient illuminance (S) of a liquid crystal display device is lower than a preliminarily set predetermined illuminance, a backlight scanning process (intermittent lighting process) is implemented (Yes of S, S), while if the ambient illuminance is not lower than the predetermined illuminance, the backlight scanning process (intermittent lighting process) is terminated (No of S, S). The light intensity of the backlight device is changed in conjunction with the high and low ambient illuminance by changing the drive current supplied to the light source, depending on the ambient illuminance of the liquid crystal display device and whether or not to implement the backlight scanning process (intermittent lighting process) (S, S).
