Patent ID: 7704681

Claim:
A manufacturing method for a pixel structure, comprising the steps of: using a first photomask to form a third patterned photoresist layer, and using the third patterned photoresist layer as a mask to form a source/drain over a substrate; using a second photomask to form a first patterned photoresist layer, using the first patterned photoresist layer as a mask to form a transparent conductive layer, using the same second photomask to form a second patterned photoresist layer, and using the second patterned photoresist layer as a mask to form a channel layer over the substrate, wherein a portion of the transparent conductive layer covers the source/drain and electrically connected to the same, and a pattern of the transparent conductive layer and a pattern of the channel layer are complementary patterns; forming a dielectric layer over the substrate to cover the transparent conductive layer and the channel layer; and using a third photomask to form a fourth patterned photoresist layer, and using the fourth patterned photoresist layer as a mask to form a gate on the dielectric layer.
