1. A method of manufacturing a touch panel for a display device, comprising:

  • forming a photosensitive insulating layer over a substrate;

    forming a first conductive layer over the photosensitive insulating layer;

    exposing the first conductive layer via a first mask including a pattern corresponding to a wiring electrode;

    removing the first mask;

    developing the exposed first conductive layer;

    forming the photosensitive insulating layer over the first conductive layer;

    forming a second conductive layer and a carrier film over the photosensitive insulating layer;

    first exposing the second conductive layer via a second mask;

    removing the carrier film;

    applying a photoresist onto the second conductive layer;

    second exposing the second conductive layer;

    developing the exposed second conductive layer; and

    forming and drying the wiring electrode over the second conductive layer and the photosensitive insulating layer, wherein each of the first and second conductive layers is formed of photosensitive silver nano wire (AgNW), and wherein the wiring electrode is electrically connected to the first conductive layer.
