Abstract

The embodiment of the invention provides a TFT (thin film transistor) array substrate, a manufacturing method for the same, and a liquid crystal displayer, relating to the field of manufacturing for liquid crystal displayer, and solving the problem that a drive signal cannot be transmitted to a display area of a substrate due to corrosion or bad bonding on a welding pad area. The TFT array substrate sequentially comprises a gate line layer, a first insulating layer, a semiconductor active layer, a data line layer, a second insulating layer, and a transparent conducting layer; and the welding pad area of the TFT array substrate comprises a plurality of leads, wherein each lead is electrically connected with at least two bonding areas. The method provided by the embodiment of the invention is used for manufacturing a TFT substrate.

Description

technical field [0001] The invention relates to the field of manufacturing liquid crystal displays, in particular to a TFT array substrate, a manufacturing method thereof, and a liquid crystal display. Background technique [0002] In the TFT-LCD (Thin Film Transistor-Liquid Crystal Display, Thin Film Field Effect Transistor-Liquid Crystal Display) manufacturing process, the TFT array substrate needs to be bonded with an integrated circuit or a flexible circuit board to transmit the driving signal to the display area of ​​the substrate. [0003] On the bonding pad area where the TFT array substrate is bonded to the integrated circuit or flexible circuit board, the lead wires are prone to corrosion and other phenomena, resulting in poor adhesion, so that the driving signal cannot be effectively transmitted to the display area of ​​the substrate, resulting in poor picture quality. . Contents of the invention [0004] Embodiments of the present invention provide a TFT array ...
