A gate driving circuit includes a plurality of stages connected to each other. An m-th stage (‘m’ is a natural number) of the stages includes a pull-up part, a pull-down part, a first holding part and a second holding part. The pull-up part outputs a high voltage of a clock signal as a high voltage of an m-th gate signal in response to a high voltage applied to a first output control part. The pull-down part pulls down the high voltage of the m-th gate signal to a first low voltage in response to a high voltage of an (m+1)-th gate signal. The first holding part holds a voltage applied to the first output control part as a second low voltage having a level lower than the first low voltage. The second holding part holds a low voltage of the m-th gate signal to the first low voltage.

Gate-driving circuitry of a thin film transistor array panel is formed on the same plane as a display area of the transistor array panel. The gate-driving circuitry includes driving circuitry and signal lines having apertures. Thus, a sufficient amount of light, even though illuminated from the thin film transistor array panel side, can reach a photosetting sealant overlapping at least in part the gate-driving circuitry. The thin film transistor array panel and the counter panel are put together air-tight and moisture-tight. Consequently, the gate-driving circuitry can avoid corrosion by moisture introduced from outside. Gate-driving circuitry malfunctions can also be reduced.
