    • A manufacturing method for an array substrate with a fringe field switching (FFS) type thin film transistor (TFT) liquid crystal display (LCD) includes the following steps. A pattern of a gate line (1), a gate electrode, a common electrode (6) and a common electrode line (5) is formed by patterning a first transparent conductive film and a first metal film formed successively on a transparent substrate. Contact holes of the gate line in the pad area and a semiconductor pattern are formed through a patterning process after a gate insulator film, and a semiconductor film and a doped semiconductor film are formed successively. A second metal film is deposited and patterned. A second transparent conductive film is deposited and a lift-off process is performed. And then, a pattern of a source electrode, a drain electrode, a TFT channel and a pixel electrode (4) is formed by etching the exposed second metal film and the doped semiconductor film.
