Problems solved by technology

[0011] However, in the inventions described in these Patent Documents 1 to 4, when forming electrodes extending in various directions or forming electrodes and active circuits on the same substrate, it is necessary to repeat the sputtering method or photolithography method multiple times. There is a problem that the manufacturing cost increases due to the structure in which wiring layers are laminated by etching methods.

Abstract

The invention provides a method for manufacturing a touch panel with low manufacturing cost, a touch panel, a display device, and an electronic apparatus. The method for manufacturing the touch panel including a substrate, a first electrode, and a second electrode, the first and second electrodes being formed on one side of the substrate in a plural numbers and extending in directions intersecting with each other, the method includes: an electrode deposition step S10 of forming an electrode film on the substrate by a plurality of first electrodes and second electrodes separated at the intersection portion with the first electrode; an insulating film forming step S30 of forming an insulating film by a printing method on at least an intersection of the first electrode with the second electrode; and a bridge wiring line forming process S40 of forming a bridge wiring line connecting the electrode films over the insulating film by the printing method.

Description

technical field [0001] The present invention relates to a manufacturing method of a touch panel, a touch panel, a display device, and electronic equipment. Background technique [0002] The capacitive touch screen is a device that forms a capacitance between the finger and the electrode of the panel by bringing a finger or the like close to a predetermined position of the panel on which the electrode is formed, and detects the current that charges the thus formed capacitance. Book a spot. For a capacitive touch panel, for example, the following are disclosed. [0003] The coordinate input device described in Patent Document 1 has a structure in which a liquid crystal layer is sandwiched between a substrate provided with X electrodes and a substrate provided with Y electrodes. And, the electrode of the detection pen close to the substrate on the X electrode side forms a floating capacitance with the X electrode and the Y electrode, and the position of the detection pen is d...
