Abstract
There is provided a touch screen panel in which sensing cells as touch sensors are formed on one surface of a substrate. The sensing cells are realized by laminating transparent conductive layers and mesh-shaped opaque metal layers. Therefore, uniform distribution of an electric field may be secured when a large area touch screen panel is realized and an operation may be performed although short is partially generated in the mesh-shaped opaque metal layers.
