Abstract
A liquid crystal display device and a method for driving the same are provided. The liquid crystal display device includes a first liquid crystal layer selectively driven by a first electric field in a first direction; and a second liquid crystal layer selectively driven a second electric field in a second direction, the second direction being different from the first direction.
Claims14
A method for driving a liquid crystal display device, the method comprising:
- displaying a video image on a first panel by selectively applying a horizontal electric field to a first liquid crystal layer of the first panel of the liquid crystal display device;
- and
- selectively applying a vertical electric field to a second liquid crystal layer of the second panel of the liquid crystal display device,
- wherein when the vertical electric field is applied, a tilt angle of the second liquid layer is from 10° to 80°, a driving voltage for generating the vertical electric field is from 1V to 4V, and a phase delay range of the light passing the second layer is from 14 nm to 120 nm.
