Abstract
A touch panel device is provided, having a cover plate, a first mask layer, a signal trace layer and a second mask layer. The cover plate has a visible area and a shield area at a side of the visible area. The shield area is divided into first, second area, third areas sequentially from the visible area to an edge of the shield area. The first mask layer disposed in the first and second areas of the shield area over a surface of the cover plate, wherein the first mask layer has a flat surface. The signal trace layer is disposed in the first area of the shield area over the flat surface. The second mask layer is at least disposed in the third area near the edge of the cover plate. A viscosity of the second mask layer is larger than a viscosity of the first mask layer.
