Abstract
A touch panel includes a substrate, a plurality of first electrodes on the substrate, a transparent conductive photoresist film on the substrate, an insulating protection layer on the transparent conductive photoresist film, a plurality of first traces electrically connecting to the first electrodes, and a plurality of second traces electrically connecting to the second electrodes. The transparent conductive photoresist film includes a transparent photoresist layer on the substrate and a conductive layer on a surface of the transparent photoresist layer away from the substrate. The transparent photoresist layer is electrically insulative and covers the first electrodes. The second traces extend through the insulating protection layer.
