Abstract
A resistive type touch panel includes an upper substrate, a lower substrate, and a porous polymer. The upper substrate has a first electrode. The lower substrate has a second electrode facing the first electrode. The porous polymer layer is disposed between the first electrode and the second electrode to increase uniformity of distance between the first electrode and the second electrode. The porous polymer layer has a plurality of openings. The first electrode and the second electrode are electrically connected to each other through the porous polymer layer when an external object makes contact with the resistive type touch panel.
