Abstract
A transparent flexible printed circuit board (FPCB) of reduced thickness but good conductivity and transparency includes an insulating resin layer. The insulating resin layer has a first surface and a second surface. At least one through hole is defined in the insulating resin layer through the first surface and the second surface. A conductive wiring layer is formed on the first surface and a wiring layer is formed on the second surface. The conductive wiring layers are made of electrically conductive resin, and have wiring openings. A cover film covers each of the conductive wiring layers, and further infills the wiring openings.
