Abstract
A display device includes: a pixel array including pixels at intersections of data lines and gate lines, a shift register including stages connected as a cascade, the shift register sequentially supplying gate pulses to the gate lines, and a node controller controlling nodes in the shift register, a first stage including: a pull-up transistor charging the output based on a Q node for a first gate pulse, a pull-down transistor discharging the output to a gate-low voltage based on a QB node voltage, a start controller pre-charging the Q node, and a QB node discharge controller discharging the QB node to a first low-potential voltage based on a first reset signal input line (IL), the node controller including a first reset signal generator that, during a vertical blanking interval of each frame, charges the first reset signal IL in response to a turn-on voltage applied to a gate-low voltage IL.
