Abstract: The present invention teaches a LCD device, including a backlight module, a first LCD panel disposed on top of the backlight module, and a second LCD panel disposed on top of the first LCD panel. The first LCD panel divides the light from the backlight module into n×m partitions, where n×m is the first LCD panel. Therefore the number of backlight partitions is significantly increased. The first LCD panel does not have a CF substrate, and therefore the first LCD panel functions like a monoc screen, controlling the transmittance of each partition and providing to the backlight partition by partition. The backlight, after being adjusted partition-wise by the first LCD panel, is then incident into the second LCD panel for color display, thereby achieving better contrast, improved display effect, and enhanced display quality.
