Abstract
A liquid crystal display device includes: a gate driver for sequentially applying a gate signal to a gate line for a horizontal line; a control signal supplier for applying a clock-shaped control signal to a control line provided in parallel to the gate line for the horizontal line; a data driver for applying a video signal to a data line provided in a direction crossing the gate line; a first liquid crystal cell provided at one side of the data line to receive said video signal under control of said gate signal and said control signal; and a second liquid crystal cell provided at an other side of the data line to receive said video signal under control of said gate signal.
