Patent ID: 7718346

Claim:
A method of forming a wiring pattern, comprising: forming a first conductive film pattern made of a first conductive film on an insulating substrate; and forming a second conductive film pattern made of a second conductive film, the second conductive film pattern intersecting with the first conductive film pattern, on the first conductive film with an insulating film interposed therebetween, wherein forming the second conductive film pattern includes: forming the insulating film covering the first conductive film pattern on the entire surface of the insulating substrate having the first conductive film pattern formed thereon, forming the second conductive film on the insulating film, wherein a step part is formed from intersecting the first conductive film pattern; forming a resist pattern, directly on the second conductive film so as to cover the step part thereof by use of a screen printing method; softening the resist pattern after drying the resist pattern to eliminate a space formed between said step part of the second conductive film and said resist pattern; hardening the resist pattern; and forming the second conductive film pattern intersecting with the first conductive film pattern, by etching and patterning the second conductive film by use of the resist pattern as a mask, wherein the softening the resist pattern comprises heating the resist pattern at a temperature lower than a curing temperature of a resist material of the resist pattern.
