Abstract
A method for manufacturing a bottom substrate of a liquid crystal display device by using only three masks is disclosed. The method includes the following steps. First, a patterned first metal layer, an insulating layer, a semiconductor layer and a second metal layer are formed subsequently on a substrate. Afterwards, the second metal layer is manufactured to have two different thicknesses by using a photolithographic process. After that, a planar layer is formed on the second metal layer and then the planar layer is etched until part of the second metal layer is exposed. Finally, a patterned transparent electrode layer is formed on the second metal layer.
