Abstract: A gate driver includes multiple stages. Each stage has a circuit portion and a wiring portion. The wiring portion delivers first and second clock signals to the circuit portion. Further, the wiring portion includes first and second clock wirings receiving the first and second clock signal, respectively, first connecting wirings electrically connecting the first clock wiring with a first every other stage, and second connecting wirings electrically connecting the second clock wiring with the odd-numbered stages. Further, the wiring portion includes third connecting wirings electrically connecting the first connecting wiring with a second every other stage and fourth connecting wirings electrically connecting the second connecting wiring with the even-numbered stages. This configuration may prevent the gate driver from operating erroneously and reduce power consumed by the gate driver.

Abstract: 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.
