Abstract:
1. A method for producing a liquid crystal display apparatus having a first substrate including a thin film transistor and a reflector on a predominantly planar insulating substrate, a second substrate having a transparent electrode and mounted facing said first substrate, and a liquid crystal layer placed between said first substrate and said second substrate; said method comprising: a first step of etching said planar insulating substrate, using a first, etching mask, to selectively form a rough surface in a preset area of said insulating substrate; a second step of etching a metal layer using a second etching mask, for selectively forming a gate electrode on a planar area of said insulating substrate, and for selectively forming a reflector having a rough surface overlying the rough surface of said insulating substrate and in isolation from said gate electrode; and a third step of etching one of a passivation film and a gate insulating film, using another etching mask, to etch the gate electrode and to etch the reflector.
