Abstract
A touch panel is provided. The touch panel having a pixel area and a sensing area includes a first substrate and an opposite second substrate. A press sensing spacer is disposed on the sensing area of the first substrate. A press sensing stage is disposed on the sensing area of the second substrate, corresponding to the press sensing spacer. An alignment layer is disposed over the second substrate, covering the press sensing stage and the pixel area of the second substrate. In an embodiment, the height of the press sensing stage is greater than the height from the surface of the second substrate at the pixel area to the bottom of the alignment layer by at least 0.05 μm.
