We here introduce a laser-driven method to pattern Ag nanowire (AgNW) transparent electrode without material removal. Our approach is to block the current flow in selected areas by cutting nanowires, which is fundamentally based on the Rayleigh instability. AgNW film spin-coated onto a glass substrate was selectively irradiated using a nanosecond-pulsed ultraviolet laser beam. This made it possible to fabricate a patterned structure consisting of spatially separated conducting and insulating regions. The feasibility of this electrical property patterning was demonstrated with white light emitting diodes attached to the fabricated pattern.
