Abstract:
A liquid crystal display device comprising:a first display unit including: a first liquid crystal display panel having a first substrate, a second substrate and a first liquid crystal layer between the first and second substrates, and a transflective film disposed under the first liquid crystal display panel, the transflective film having a plurality of layers in which a first layer and a second layer each having a different refractivity index are alternately stacked, so that the transflective film partially reflects and partially transmits an incident light incident onto the transflective film; a second display unit including a second liquid crystal display panel having a third substrate, a fourth substrate and a second liquid crystal layer between the third and fourth substrates; and a light supplying unit disposed between the first and second display units, the light supplying unit generating a first light to provide the first display unit with a first part of the first light and the second display unit with a second part of the first light, and the light supplying unit controlling an amount of the first and second parts of the first light to regulate a contrast ratio of a luminance between the first and second display units.
