Abstract:
1. A display device, dividing a single frame into m number of sub-frames, where m is an integer not less than 2, so as to display an image, said display device comprising: a display section for displaying an image whose luminance is based on a luminance gradation of a display signal; and a control section for generating first to m-th display signals in first to m-th sub-frames so that division of the frame does not vary a total luminance outputted from the display section in a single frame and for outputting the first to m-th display signals to the display section, wherein the first to m-th display signals include (i) a display signal whose luminance gradation is adjusted to any of a minimum value, a value smaller than a first value, a maximum value, and a value larger than a second value, the second value being relatively larger than the first value and (ii) a display signal whose luminance gradation is adjusted to a value other than the minimum value, the value smaller than the first value, the maximum value, and the value larger than the second value, the display section is set to cause a liquid crystal panel to display an image, and the control section is designed to vary a polarity of a voltage applied to liquid crystal at a sub-frame cycle within a same frame cycle.
