Abstract

An optical-interference type display panel and a method for making the same are disclosed, wherein the display panel has a substrate on which multiple first conductive optical film stacks, supporting layers and multiple second conductive optical film stacks are formed. The substrate further has a plurality of connecting pads consisting of a transparent conductive film of the first conductive optical film stacks. Since the transparent conductive film is made of indium tin oxide, these connecting pads have the excellent anti-oxidation ability at their surface.
