Patent ID: 7554518

Claim:
A liquid crystal display including a panel unit having first and second panels and a liquid crystal layer interposed between the two panels, comprising: a plurality of pixels each including a switching element; gate lines and data lines connected to the switching elements; a gate driver circuit for applying gate signals to the gate lines; a driving circuitry chip for applying data voltages to the data lines; a plurality of transmission gates connected between the data lines and the driving circuitry chip; first to third voltage lines disposed along an edge of the panel unit in a ring shape; fourth to sixth voltage lines disposed along an edge of the panel unit in a ring shape, and disposed at outer sides of the first to third voltage lines, respectively; a first diode unit including a first diode group connected in series between the second voltage line and the fifth voltage line, wherein the first diode group includes a plurality of diodes; and a second diode unit including a second diode group connected in series between the third voltage line and the sixth voltage line, wherein the second diode group includes a plurality of diodes, wherein one end of each of the data lines is connected to a first common connection point between two of the series connected diodes group and the other end of the data lines is connected to a second common connection point between two of the series connected diodes in the second diode group via a transmission gate, and further wherein at least one of the first common connection point between the data lines and the first diode group and the second common connection point of contact between the data lines and the second diode group is less than a threshold voltage of the liquid crystal.
