Abstract
A touch screen panel includes a thin film substrate having sensing patterns formed thereon that is implemented as an isotropic film, and a polarizing plate is disposed on the sensing patterns so that it is possible to minimize or reduce degradation of image quality. The touch screen panel includes a thin film substrate, sensing patterns, and sensing lines. The thin film substrate is divided into an active area and a non-active area. The sensing patterns are formed in the active area of the thin film substrate. The sensing lines are formed in the non-active area of the thin film substrate so as to be connected to the sensing patterns. In the touch screen panel, the thin film substrate is implemented as an isotropic film.
