Abstract
A manufacturing method of pixel structure includes: sequentially forming a gate, a gate insulation layer, a semiconductor layer and a conductive layer on a substrate; forming a first patterned photoresist layer including multiple first photoresist blocks and multiple second photoresist blocks on the conductive layer; reducing the thickness of the first patterned photoresist layer until the second photoresist blocks are completely removed; forming a pixel electrode layer and a second photoresist layer on a partial pixel electrode layer; removing a part of the pixel electrode layer exposed by the second photoresist layer, a partial conductive layer and a partial semiconductor layer both under the removed pixel electrode layer to define a first electrode block, a second electrode block and a channel region; removing the remained first patterned photoresist layer and second photoresist layer and forming a protective layer and a common electrode layer on a part of the protective layer.
