LIQUID CRYSTAL DISPLAY

摘要

A liquid crystal display (LCD) includes thin film transistors (TFTs) respectively coupled to different gate lines and to a pixel electrode and a direction control electrode, and to which different gate-off voltages are respectively applied. Alternatively, a reduced gate voltage is applied to the pixel electrode TFT according to a coupling capacitance. Alternatively, the pixel and direction control TFTs are coupled to the same gate line, and portions of a gate insulating layer are formed with different thicknesses. Resulting differences in the voltages respectively applied to the two TFTs or in the electric fields respectively applied to the two electrodes prevent leakage current of the direction control electrode TFT, thereby enabling stable multi-domains to be implemented in the LCD without applying a high voltage.
