Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of improving display image quality when performing time division display of a plurality of videos by using a light source which performs partial light emitting operation, and a video display system using such a liquid crystal display device. SOLUTION: A partial driving processing part 42 generates a commonalized video (video signal D2) which is a common video to right and left videos by obtaining the maximum luminance level between the right and left videos for every pixel 20 based on an input video signal Din (video signal D1). Also, a light emission pattern signal BL1 and a video signal D4 for partial driving are each generated by using the commonalized video. Temporal variation of display luminance between the right and left videos is avoided without reducing the display luminance (while maintaining the display luminance), thereby suppressing generation of flickers.
