Abstract
A liquid crystal display device is disclosed, which includes a first substrate, a second substrate and a liquid crystal layer containing Chiral dopants. The second substrate includes a blue sub-pixel region and a blue sub-pixel electrode unit disposed in the blue sub-pixel region. The numerical ranges of the characteristic parameters of the liquid crystal layer are 0.33≦Δnd≦0.62 and 0.2≦d/p≦0.36. The ratio of the area of the hollowed regions in the blue sub-pixel region, to the area of the blue sub-pixel region, is larger than or equal to 54%.
