Abstract
A manufacturing method of a touch panel, comprising forming a pattern of a metal connecting layer, a pattern of an insulating layer, a pattern of a driving electrode, a pattern of a sensing electrode and a pattern of a protective layer on a substrate; the pattern of the insulating layer and the pattern of the protective layer are formed through the same mask. With this method, the number of masks used during manufacture of the touch panel can be decreased, and the production cost is reduced. A touch panel is further disclosed.
