Abstract:
1. A liquid crystal display device comprising: a liquid crystal panel and a video signal control circuit which supplies video signals to the liquid crystal panel, wherein the video signal control circuit includes a first frame memory, a second frame memory, a first switching element, and a second switching element, the video signal control circuit is configured to convert a frame driving frequency to be faster than an average response time of human eyes by adjusting a reading-out speed of parallel digital data from the first frame memory and the second frame memory, the liquid crystal panel includes a first substrate and a second substrate, a columnar spacer is disposed between the first substrate and the second substrate, in a first frame, the first switching element outputs parallel digital data from the first frame memory and the second switching element inputs parallel digital data to the second frame memory, and in a second frame, the first switching element outputs parallel digital data from the second frame memory and the second switching element inputs parallel digital data to the first frame memory.
