Patent ID: 8094251

Claim:
A method for manufacturing a lower substrate of a liquid crystal display device, comprising: (a) forming a patterned first transparent electrode layer, a first insulation layer, a patterned metal layer, and a second insulation layer over a first surface of a substrate, wherein the first transparent layer is covered by the first insulation layer, the patterned metal layer locates on the first insulation layer, and the patterned metal layer is covered by the second insulation layer; (b) forming a second transparent electrode layer and a negative photoresist layer over the second insulation layer, wherein the second transparent electrode layer locates between the second insulation layer and the negative photoresist; (c) exposing the substrate from a second surface of the substrate, wherein the second surface is opposing to the first surface of the substrate; (d) removing the non-reacted negative photoresist; and (e) forming a patterned second transparent electrode.
