Outline of Final Research Achievements

Organic transparent conductive films can be supplied in low cost and stable. However, this film has poor visibility, the case of forming the circuit, it was a problem that could not be obtained transparency. In this study, it was attempted to isolate the film by photo-dissociation action of ultra-short pulse laser. As a result, it is possible to form a circuit without removing the membranes and was able to enhance visibility. In addition, a touch panel was produced by overlaying to produce two circuit boards by utilizing this effect. It was confirmed to function as a result a touch panel.
