Abstract
According to the method of manufacturing an optical matrix device of this invention, lyophobic portions which are lyophobic, and lyophilic portions which are lyophilic, with respect to metal ink are formed alternately and parallel, and with a pitch smaller than a width of droplets applied by printing technique, on a foundation of wires to be formed on a substrate. Thus, the ejected droplets extend along edges of the lyophobic portions, while straddling the plurality of lyophobic portions, thereby to improve the accuracy of wire formation. This can form a uniform wire width, and eliminate a possibility of a formed wire making a short circuit with an adjacent wire.

A method of manufacturing an optical matrix device for manufacturing, by a printing technique of applying a fluid, the optical matrix device constructed with elements relating to light arranged in a two-dimensional matrix form, the method comprising:
- a first insulating film forming step for forming a first insulating film on a surface of a substrate of the optical matrix device;
- a first foundation pattern forming step for forming a first foundation pattern with lyophilic portions and lyophobic portions formed substantially parallel thereon, by treating part of a surface of the first insulating film to be lyophobic with respect to the fluid;
- and
- a first wire forming step for forming wires by applying the fluid to be substantially parallel to a direction of long sides of the lyophobic portions on the first foundation pattern, and to straddle a plurality of the lyophobic portions.
