electrode driver of the present invention provides the storage driving voltage more than two times after charging pixels the third transistor qi 3 is turned on and supplies a high level vh with the i_th storage electrode lines once again when von is applied to the i 3_th gate line therefore the size of each transistor of the second and third transistor can be reduced because the boosting voltage supplying duration is doubled the liquid crystal panel may include 2n 1 additional gate lines because the second transistor of the last stage needs a next gate line to be connected and each third transistor of the last 2n 1 stages needs a 2n 1th next gate line respectively for example when the liquid crystal has 100 gate lines and 100 storage electrode lines s and n is 1 the gate electrode of the third transistor in the 98th 99th and 100th stage needs a 101th 102th and 103th gate line respectively to be connected to these 101th 102th and 103th gate lines are additional gate lines which sequentially shifted turn on voltages are applied and are not connected to pixel transistors instead of forming additional gate lines on the liquid crystal panel output terminals outputting sequentially shifted turn on signals can.
