Abstract
A lower substrate for a liquid crystal display device and the method of making the same are disclosed. The method includes steps of: (a) providing a substrate; (b) forming a patterned transparent layer having plural recess on the substrate; (c) forming a first barrier layer on the surface of the recess; (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; and (e) forming a first insulated layer and a semi-conductive layer in sequence. The method further can optionally comprise the steps of: (f) forming a patterned second metal layer, wherein part of the semi-conductive layer is exposed, thus forming the source electrode and the drain electrode; and (g) forming a transparent electrode layer on part of the transparent layer and part of the second metal layer.
