Problems solved by technology

[0015] However, compared with the external connection terminal composed of the whole film, the external connection terminal composed of the fine line mesh formed by printing in this way generally cannot avoid the increase of contact resistance, and it is difficult to obtain a good and stable electrical connection state due to this point. The problem

Embodiment Construction

[0032] Hereinafter, examples of this invention will be described.

[0033] Figure 4A , Figure 4B and Figure 5 The details of the external connection terminals included in one embodiment of the touch panel of the present invention are shown, Figure 6 It is an example of the touch panel of this invention which shows the FPC which connected the external circuit to the external connection terminal.

[0034] The touch panel is used in this example with figure 1 The touch panel of the conventional example shown is different in the structure of the external connection terminals formed in the center part of one long side of the base material 10 and the structure in the sensing area 20, and other structures are the same as figure 1 The structures shown are essentially the same. In addition, in Figure 6 The detailed illustration of the structure in the sensing region 20 is omitted in FIG.

[0035] The touch panel has a first conductive layer made of first cured conductive in...

Abstract

The invention provides a touch panel and a touch panel production method. The touch panel comprises, a substrate, a layered structure formed in a sensing region defined on one side of the substrate, the layered structure including at least a first conductor layer made of a first hardened conductive ink, a second conductor layer made of a second hardened conductive ink and an insulating layer disposed therebetween, and an external connection terminal formed outside the sensing region on the one side of the substrate, wherein the external connection terminal comprises a first terminal layer madeof the first hardened conductive ink and a second terminal layer made of the second hardened conductive ink, such that the first terminal layer and the second terminal layer are directly overlaid oneach other.

Description

technical field [0001] The invention relates to a touch panel produced by a printing method and a production method of the touch panel. Background technique [0002] As a conventional example of such a touch panel, figure 1 and Figure 2A , Figure 2B The configuration of the capacitive touch panel described in Japanese Patent Application Publication No. 2017-103317 (published on June 8, 2017, hereinafter referred to as Document 1) is shown. This touch panel has a structure in which a first conductive layer, an insulating layer, a second conductive layer, and a protective film are sequentially laminated on a transparent base material (substrate) 10 . figure 1 In , the part surrounded by the rectangular frame is the sensing region (sensor region) 20 where the sensor electrodes are located. figure 1 A detailed illustration of the sensor electrodes is omitted in . [0003] The sensor electrode is composed of a first sensor electrode and a second sensor electrode, the first...
