Display Device with Touch Panel

摘要

A manufacturing method of a touch panel includes the steps of providing a substrate, forming a first conductive film on the substrate, forming a first mask on the first conductive film, etching the first conductive film to form electrode portions and lower intersect portions of the touch panel, forming an insulating film made of a negative resist on the first conductive film, and forming a contact hole above the electrode portion by removing the insulating film. The steps further include forming a second conductive film on the insulating film, forming a second mask on the second conductive film, etching the second conductive film to form an upper intersect portion connected between two adjacent electrode portions via the contact hole and intersecting with the lower intersect portion, and forming protective film on the second conductive film.

主权项

1. A touch panel comprising:
a substrate; a plurality of electrodes formed on the substrate, the plurality of electrodes including a first group of electrodes and a second group of electrodes, each of the first group of electrodes having a contact portion; an insulating film made of a negative resist and formed on the plurality of electrodes; an intersecting electrode formed on the insulating film and intersecting with each of the second group of electrodes; and a protective film formed on the intersecting electrode; wherein each of the first group of electrodes is exposed from the insulating film at the contact portion, and wherein the intersecting electrode is connected to each of the first group of electrodes at the contact portion.
