The second liquid crystal is stacked on the first liquid crystal panel. The backlight module is set below the first liquid crystal panel and the second liquid crystal panel. The first liquid crystal panel and the second liquid crystal panel are similar as shape and size and both have a same pixel arrangement. Each pixel on the first liquid crystal panel is aligned with a corresponding pixel on the second liquid crystal panel. The first liquid crystal panel is a normal white liquid crystal panel. The second liquid crystal is a normal black liquid crystal panel. A light from the backlight module orderly passes through the first liquid crystal panel and the second liquid crystal panel and is modulated to display an image.
