ABSTRACT:
A method for manufacturing a liquid crystal display which employs an active matrix substrate including a plurality of pixels arranged in matrix on a substrate and reflecting electrodes formed in the pixels, respectively. The method comprises (a) a laminated conductive film formation step of sequentially forming a conductive metal film and an amorphous transparent conductive film on a substrate to form a laminated conductive film and (b) a reflecting electrode formation step of patterning the laminated conductive film into a reflecting electrode, wherein the step (b) includes a first etching step of etching the conductive metal film and the amorphous transparent conductive film simultaneously and a second etching step of etching the amorphous transparent conductive film only.
