Zusammenfassung:	A liquid crystal display apparatus using a backlight (104) for display includes: a video signal time compression circuit (101) for compressing a video signal in the time axis direction and outputting the time-compressed video signal; an LCD controller (106) for driving a liquid crystal panel (105) based on the time-compressed video signal; a source driver (107) and a gate driver (108); a motion detection circuit (2) for detecting the amount of motion of a display image based on the video signal; a PWM modulation pulse generation circuit (4) for generating modulation pulses different in frequency according to the detection result from the motion detection circuit (2); and an inverter (103) for lighting up the backlight (104) based on the modulation pulses, to thereby enable reduction of image contour blurring in a moving image and reduction of flicker in a still image.
