Abstract:
1. A touch panel, having a pixel area and a sensing area, comprising: a first substrate; a press sensing spacer disposed on the sensing area of the first substrate; a second substrate disposed opposite to the first substrate; a press sensing stage disposed on the sensing area of the second substrate, corresponding to the press sensing spacer; and a first alignment layer disposed over the press sensing stage and a surface of the pixel area of the second substrate, wherein the press sensing stage has a first height, and a second height is defined from the surface of the pixel area of the second substrate to a bottom of the first alignment layer, and wherein the first height is greater than the second height by at least 0.05 μm, and the press sensing stage comprises at least one metal layer, at least one dielectric layer, a conductive layer and a protection coating layer, wherein the dielectric layer is disposed between the metal layer and the conductive layer, the protection coating layer is disposed between the conductive layer and the dielectric layer, and the protection coating layer is only located directly below the press sensing spacer.
