  • Patent number: 7804553
    Abstract: A liquid crystal display including a LC panel including a first display panel having first to n-th gate lines (n>2) and data lines crossing the gate lines and forming a pixel, and a second display panel which faces the first display panel, the aperture ratio of a first pixel line electrically connected to the first gate line is smaller than that of a second to a n-th pixel line electrically connected to the second to the n-th gate line, respectively, and a gate driver having first and the second pull-down transistors which decrease the voltage of each gate line to a low level, the first and second pull-down transistors are connected to start and end terminals of the each gate line, a width-to-length ratio of a channel of the second pull-down transistor is 0.8 to 3 times as large as that of a channel of the first pull-down transistor.
