Abstract
A thin film transistor (TFT) array substrate with few processing steps and simple structure is provided, wherein merely two patterned metal layers are required and a patterned planarization layer is adopted to separate the two patterned metal layers from each other and thereby reduce power loading. In addition, the patterned planarization layer has slots to form height differences so as to separate scan lines from common electrodes to further reduce the power loading.
