Tft array substrate, manufacturing method and liquid crystal display panel

A manufacturing method of a TFT array substrate, comprising the steps of:

• forming a thin film transistor layer on a base substrate of a TFT array substrate, forming a plurality of thin film transistor units on the thin film transistor layer, each thin film transistor unit comprising a gate, a gate insulating layer, an active layer, a source and a drain;
• forming a passivation layer arranged on the thin film transistor layer and forming at least one via hole on the passivation layer, wherein a via hole exposes the source of the thin film transistor unit;
• forming a pixel electrode on the passivation layer, extending the pixel electrode toward the via hole and electrically connecting to the source;
• forming supporters in the at least one via hole, wherein upper ends of the supporters have a same horizontal surface for supporting a lower surface of a CF substrate in a pair with the TFT array substrate;
• and
• forming an alignment layer on the passivation layer and the pixel electrode.
