US 9,753,593 B2 · Touch panel and method of manufacturing the same

Abstract

A touch panel for a display device and a method of manufacturing the same are disclosed. In one aspect, the method includes forming a photosensitive insulating layer over a substrate and forming a first conductive layer over the photosensitive insulating layer. The method also includes 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 and forming the photosensitive insulating layer over the first conductive layer. The method further includes forming a second conductive layer and a carrier film over the photosensitive insulating layer and first exposing the second conductive layer via a second mask; removing the carrier film. The method also includes developing the exposed second conductive layer, and forming and drying the wiring electrode over the second conductive layer and the photosensitive insulating layer.
