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.

Claims

1. A thin film transistor array panel, the thin film transistor array panel having a gate line, a data line, a pixel electrode, a thin film transistor and a gate driving circuit formed on a substrate, the gate driving circuit comprising:

a driving circuitry outputting a gate signal to the gate line; and

a first signal line electrically connected to the driving circuit, wherein an aperture is formed in the first signal line.
