Patent ID: 7456923

Claim:
A liquid crystal display device, comprising: a plurality of data lines; a plurality of gate lines provided in a direction crossing the data lines; first and second control lines provided in a direction being parallel to the gate lines; first liquid crystal cells provided at one side of each data line; second liquid crystal cells provided at the other side of each data line; a first switching part provided for each first liquid crystal cell to apply video signals supplied from the data lines to the first liquid crystal cells under control of the second control line and the gate line; and a second switching part provided for each second liquid crystal cell to apply video signals supplied from the data lines to the second liquid crystal cells under control of the first control line and the gate line; wherein the first switching part comprises: a first thin film transistor connected to the data line and the gate line, wherein the first thin film transistor is turned on when said gate signal is applied to the gate line, thereby receiving said video signal from the data line; and a second thin film transistor connected to output terminal of the first thin film transistor and the second control line, wherein the second thin film transistor is turned on upon applying a control signal to the second control line to thereby applying said video signal from the output terminal of the first thin film transistor to the first liquid crystal cell.
