SHIFT REGISTER, DISPLAY DEVICE HAVING THE SAME AND METHOD OF DRIVING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a shift register wherein high image quality of a display device can be maintained for a further long time by enhancing reliability of a driving circuit of a display panel without obstructing miniaturization of the driving circuit and stably adjusting the potential of a gate line for a further long time.

SOLUTION: A first pull up drive control section (51) receives a gate signal (GOUTM-1) from the last adjacent stage and outputs a control signal (CNTRM) based on the gate signal. A pull up drive section (53) outputs a first clock signal (CLK) as the gate signal (GOUTM-1) to a corresponding gate line through an output terminal (OUT) in response to the control signal (CNTRM). A pull down drive section (54) inactivates the corresponding gate line connected to the output terminal (OUT) in response to a second clock signal (CKB). A pull down transistor (Td) is turned on or off in response to the second clock signal (CKB).
