Abstract: The present invention discloses a touch screen substrate and a method of manufacturing the same. The touch screen substrate includes a capacitance layer comprising a plurality of electrodes, a first cover layer formed on the capacitance layer; a plurality of conductive bridges located on the first cover layer and configured to be electrically connected to a part of the electrodes that are electrically isolated; and a plurality of electrical connection lines, configured to respectively be electrically connected to the respective conductive bridge so as to electrically connect the first electrode with a touch detecting circuit. A material layer for forming the electrical connection lines is different from a material layer for forming the conductive bridges such that the conductive bridges located below the electrical connection lines are not corroded when the material layer for the electrical connection lines is etched. Utilization of different chemical properties of copper and silver nanowires and ITO material and inclusion of a single patterning process increase productivity and yield.
