In a video display device and system, a timing control section performs timing control for right- and left-eye video signals and to each have a blanking period whose length (Duty) is longer than that of a first-time blanking period Tb1 at least once in second-time and later blanking periods, e.g., performs timing control for a second-time blanking period Tb2 to be longer in Duty than the first-time blanking period Tb1. With such timing control, for stereoscopic display video viewing using open-state shutter glasses in the second-time blanking period Tb2 with a sequential write mode, there are advantages that the shutter glasses can remain longer in the open state while the response characteristics of the liquid crystal material being enhanced. As such, with the resulting video display device and system, the occurrence of crosstalk can be favorably prevented at the same time as reducing any reduction in display brightness.
