  • Patent number: 10088966
    Abstract: A touch screen panel includes a base substrate, a sensing pattern layer on the base substrate, the sensing pattern layer including a plurality of sensing patterns formed on the base substrate, an insulation layer on the sensing pattern layer, and a bridge electrode formed on the insulation layer to electrically connect unit patterns isolated from each other of the sensing pattern layer. The insulation layer and the bridge electrode satisfy parameters according to specific equations so that a visibility of the bridge electrode on the insulation layer is decreased and an image visibility is improved.

  • Patent number: 9760228
    Abstract: Disclosed is a transparent electrode pattern structure including: a first transparent electrode layer and a second transparent electrode layer which are stacked on a transparent substrate in a predetermined pattern, respectively; an insulation layer disposed between the first transparent electrode layer and the second transparent electrode layer; and contact holes formed in the insulation layer to electrically connect the first transparent electrode layer with the second transparent electrode layer; wherein the first transparent electrode layer and the second transparent electrode layer have a thickness of 100 to 200 nm, respectively, and the insulation layer has a thickness of 1,000 to 2,000 nm, thereby considerably decreasing a difference in reflectance on separate positions, as well as a touch screen panel including the transparent electrode pattern structure.
