Abstract:
1. A method for manufacturing a bottom substrate of a liquid crystal display, comprising the steps of: (A) providing a substrate; (B) forming a patterned first metal layer on the substrate by using a first mask; (C) forming a first insulating layer on the patterned first metal layer and the substrate; (D) forming a patterned semiconductor layer on the first insulating layer by using the first mask, wherein the semiconductor layer is formed above the first metal layer; (E) forming a patterned second metal layer on the patterned semiconductor layer; (F) forming a second insulating layer on the patterned second metal layer, the semiconductor layer and the first insulating layer, and then patterning the second insulating layer; and (G) forming a transparent electrode layer on the second insulating layer and then patterning the transparent electrode layer.
