Patent ID: 6881535

Claim:
A method for producing a liquid crystal display apparatus having a first substrate including a thin film transistor and a reflector on an 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 forming an etching mask, patterned to a predetermined shape, on at least one of a metal layer, an insulating layer and a semiconductor layer, formed on said insulating substrate; a second step of etching at least one of said metal layer, insulating layer and the semiconductor layer, using said etching mask, to expose portions of said insulating substrate and to form on said insulating substrate at least a constituent portion of said thin film transistor and a plurality of protrusions separated from said constituent portion; a third step of causing only said etching mask to reflow to cover an exposed part of said constituent portion of said thin film transistor and near-by surface portions of said insulating substrate with said etching mask and to cover exposed surfaces of said protrusions and near-by surface portions of said insulating substrate, the reflow of the etching mask leaving exposed the surface portions of said insulating substrate located between neighboring protrusions; a fourth step of etching said insulating substrate, following said third step, using said etching mask to form one or more recesses in the exposed areas of said insulating substrate, the protrusions and recesses forming a rough surface; and a fifth step of selectively forming a reflector having a rough surface on the rough surface formed at least by said protrusions and recesses.
