Abstract:
1. A method for manufacturing a lower substrate for use in a liquid crystal display (LCD) device, comprising: (a) providing a substrate; (b) forming a patterned transparent layer on the substrate with a mask, thereby forming plural recesses in the patterned transparent layer; (c) forming a first barrier layer on the surface of the recesses with the mask; (d) coating a first metal layer on the first barrier layer and making the surfaces of the first metal layer and the transparent layer in substantially the same plane; (e) forming a second barrier layer on the surface of the first metal layer by annealing; and (f) forming a first insulated layer and then a semi-conductive layer on the second barrier layer and the part transparent layer; wherein the mask for forming the first barrier layer in step (c) is the same mask for forming the plural recesses in the patterned transparent layer in step (b); patterning the first insulated layer and the semi-conductive layer with a mask after the step (f); wherein the mask for patterning the first insulated layer and the semi-conductive layer is the same mask for forming the plural recesses in the patterned transparent layer in step (b).
