Liquid crystal display device
First Claim
1. 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, 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.

Abstract
Disclosed is an LCD device for performing bi-directional display. The LCD device includes first and second display units, and a light supplying unit. The first display unit includes an LCD panel and a transflective film that is disposed under the LCD panel and has layers in which first and second layers having different refractivity indexes are alternately stacked. The transflective film partially reflects and transmits light incident onto the film. The light supplying unit is disposed between the first and second display units, and provide the first and second display units with light generated from a lamp by dividing the light, to thereby regulate a contrast ratio of a luminance between the first and second display units. Therefore, the structure of an LCD panel for performing bi-directional image display can be simplified, and the light loss in the transmission mode can be reduced.

24. 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 disposed between the first and second substrates, and a first transflective film disposed under the first liquid crystal display panel, the first 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 first transflective film partially reflects and partially transmits a first incident light incident onto the first 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 disposed between the third and fourth substrates; and
a light supplying unit disposed between the first and second display units, the light supplying unit dividing a first light, which is a first part of a light generated from an light source, into a third light and a fourth light to provide the first and second display units with the third and fourth light, respectively, and dividing a second light, which is a second part of the light generated from the light source, into a fifth light and a sixth light to provide the second and first display units with the fifth and sixth light, respectively, the light supplying unit controlling an amount of the third, fourth, fifth and sixth light to regulate a contrast ratio of a luminance between the first and second display units. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33)
