Problems solved by technology

In addition, there is a problem that the variation in the wiring resistance of each wiring layer becomes large.
[0007] In addition, in the invention described in Patent Document 2, the longer the length dimension of the wiring layer, the narrower the wiring width is, so the problem of disconnection is more likely to occur, and the variation in wiring resistance further increases.

Abstract

The invention provides an input device and a method of manufacturing the same. A wiring layer comprises a plurality of wires provided with connecting end parts which are configured at a connection position connected with the end part of an electrode layer and; and wiring extension parts which are pulled out from the connecting end parts. Each connecting end is the widest wiring part in each wiring layer, when the two orthogonal directions in a plane is set as a first direction and a second direction, the wiring extension parts within a plurality of said wiring layers are extended respectively in the second direction in a state where there are a gaps in the first direction on the non-input area side on the same side as the input area, while the wire width of each of the wiring extension part is provided in proximity in a row arrangement in the first direction, and is such that the less the number of areas of wiring layers, the larger the wire width.

Description

[0001] This application is a divisional application, the application number of its parent application: 201180018663.0, the filing date: 2011.07.06, the title of the invention: input device and its manufacturing method. technical field [0002] The present invention relates to an input device configured by extending and forming a plurality of wiring layers in a non-input area located outside the input area, and particularly relates to the structure of the wiring layers. Background technique [0003] The configuration of the input device (touch panel) is disclosed in the following patent documents 1 and 2. FIG. A plurality of electrode layers are arranged in the input area of ​​the input device. In addition, when the operator operates the input area with a finger or the like, the operation position can be detected by a change in electrostatic capacitance or the like. A wiring layer electrically connected to each electrode layer is formed in a non-input area outside the input ...
