Claim:
1. A manufacture method of a thin film transistor (TFT) array substrate, comprising steps of: step step step step step step forming a first pixel electrode layer on the second protecting layer and the portion of the second metal electrode exposed in the via; coating the organic material layer on the first pixel electrode layer so that the organic material fills up the via; removing portions of the organic material layer that are located outside and around the via such that a remaining portion of the organic material layer is left in the via and a portion of the first pixel electrode layer that is located outside and around the via is exposed; forming a second pixel electrode layer on the exposed portion of the first pixel electrode layer that is located outside the via and the remaining portion of the organic material layer that is left in the via; and patterning the first pixel electrode layer and the second pixel electrode layer at the same time with one photolithography process to form, respectively, a first pixel electrode and a second pixel electrode that collectively form a pixel electrode that is connected to the second metal electrode through the via.
