发明名称 SHIFT REGISTER AND LIQUID CRYSTAL DISPLAY DEVICE USING THE SAME
摘要 A shift register and an LCD(Liquid Crystal Display) device using the same are provided to increase the lifespan of a driver by reducing a high voltage maintain interval in a node for controlling a pull-down transistor. A shift register includes first and second stages(51,52), and first and second wires(81,82). The first stage charges a first output terminal in response to a voltage of a first node(Q_A), discharges the first output terminal in response to a voltage of a second node(QB_O_A), and includes a third node(QB_E_A). The second stage, which is driven by the voltage of the first output terminal, charges a second output terminal in response to a voltage of a fourth node(Q_B), discharges the second output terminal in response to the voltage of a sixth node(QB_E_B), and includes a fifth node(QB_O_B). The first wire connects the second and fifth node. The second wire connects the third and sixth node.
