Problems solved by technology

However, irradiation from the TFT array panel side may result in insufficient light to harden the encapsulant, especially when the width of the signal lines or transistors in the gate drive circuit is greater than 100 μm
As a result, the two panels may be susceptible to moisture ingress through the insufficiently hardened encapsulant, causing corrosion of the gate drive circuitry

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.

Description

technical field [0001] The present invention relates to display device technology, and more particularly, relates to the design and application of a thin film transistor array panel and a display device including such a thin film transistor array panel. Background technique [0002] Generally, a display device includes a display panel, a gate driving circuit and a data driving circuit. The display panel includes a thin film transistor array panel having gate lines, data lines, pixel electrodes, and thin film transistors; an opposite panel having one or more common electrodes; and a liquid crystal layer provided between the two panels. The two panels are aligned and sealed with sealant. The gate driving circuit and data driving circuit are usually provided on a printed circuit board, or as an integrated circuit connected to the display panel. [0003] Recently, in order to minimize device size and increase efficiency, gate driving circuits have been directly formed on thin ...
