Abstract
Provided is a pressure sensor for a touch panel, including a signal input member configured to have conductors patterned thereon in an interdigitated form on a substrate, a spacer disposed at a corner where the conductor patterns are not formed on the substrate of the signal input member, and a piezo film disposed over the spacer, spaced apart from the signal input member, and configured to have a resistance value varied depending on the amount of pressure applied to the piezo film, wherein an interval between the conductor patterns formed in the signal input member and disposed close to the spacer is smaller than an interval between the conductor patterns formed in the signal input member and disposed at the farthest place from the spacer.
