Touch panel

摘要

The present invention relates to a touch panel which can detect touch securely without being affected by drive of an underlying display panel and shield external static electricity, securely, the touch panel includes a substrate having an active region and a peripheral region surrounding the active region; a plurality of first electrodes and second electrodes formed on the active region in a row direction and a column direction, respectively; a plurality of pad electrodes on one side of the peripheral region; routing lines for connecting ends of the first electrodes and the second electrodes to the pad electrodes, respectively; and a transparent conductive layer formed at the peripheral region to cover the routing lines.

1. A touch panel comprising:
a substrate having an active region and a peripheral region surrounding the active region; a plurality of first electrodes and second electrodes formed on the active region in a row direction and a column direction, respectively; a plurality of pad electrodes on one side of the peripheral region; routing lines for connecting ends of the first electrodes and the second electrodes to the pad electrodes, respectively; a first insulating film formed between the substrate and the routing lines; a guide ring line formed on the first insulating film and on an outer region of the routing lines; a second insulating film formed over the guide ring line and the routing lines; and a transparent conductive layer including first and second conductive films formed of indium tin oxide (ITO), the first conductive film formed above the substrate and formed under both the first insulating film and the guide ring line, the first conductive film being directly connected to the guide ring line, the second conductive film formed over the guide ring line and the first insulating film at the peripheral region to cover the routing lines, the second conductive film being directly connected to the guide ring line to have an electrical connection with the guide ring line, wherein the transparent conductive layer has a region falling under the peripheral region.
