Abstract

A manufacturing method of a touch panel is provided. The method includes the following steps. A conductive layer is formed on a substrate, and a dielectric layer is formed to cover the conductive layer. The conductive layer and the dielectric layer are then patterned to respectively form several sensing wires and several dielectric blocks by using a first mask, which is a half-tone mask. Next, a transparent conductive layer is first formed to cover the conductive layer and the dielectric layer, and is then patterned to form a touch sensing structure by using a second mask.

First claim

What is claimed is:

1. A touch panel, comprising:
a substrate;
a first sensing wire, formed on the substrate;
a dielectric block, formed on the first sensing wire and comprising two through holes, wherein the first sensing wire is exposed from the two through holes; and
a touch sensing structure, covering the dielectric block and extending to the first sensing wire via the two through holes;
wherein, an outer lateral surface of the first sensing wire is connected to an out…
