Abstract
A touch screen panel includes a transparent substrate having a screen area, a black matrix area adjacent to an outside of the screen area, and a decoration pattern area in the black matrix area. The touch screen panel also includes a plurality of conductive sensing cells in the screen area, and a black matrix corresponding to the black matrix area. The black matrix is on one surface of the transparent substrate, and the black matrix has one or more openings formed in the decoration pattern area. The touch screen panel further includes a conductive decoration pattern in the opening of the black matrix, and the conductive decoration pattern is grounded through a ground line connected thereto.
