Abstract
In a method of making an electronic device having at least a transparent conductive layer, which includes at least a step of forming a transparent conductive layer member and a step of forming a transparent conductive layer by patterning the transparent conductive layer member using a spot-shaped or linear laser beam or beams, each of which has a short wavelength of 400 nm or less and optical energy greater than the optical energy band gap of the transparent conductive layer.
