Abstract
The present invention provides an FFS type TFT array substrate and a manufacturing method thereof. The manufacturing method for an FFS type TFT array substrate of the present invention comprises that a gate electrode, a scanning line, a common electrode, and a common electrode line are formed in one photomask process. Comparing with the conventional art, the present invention simplifies the manufacturing process, with fewer photomasks, and a shorter processing time, therefore, the production cost is low. The fabrication process of the FFS type TFT array substrate of the present invention is simple, has low production cost and excellent electrical performance.
