touch panel

Abstract

The invention provides a touch panel. In a touch panel having a structure in which a first layer on which first sensor electrodes made of a fine wire grid is formed and a second layer on which a second sensor electrode made of a thin wire grid are formed overlap via a transparent insulator The first sensor electrodes and the first dummy wiring forming the first grid pattern are provided on the first layer, and the second sensor electrodes and the second dummy wiring forming the second grid pattern are provided on the second layer. The pair of arrangement period directions of the first grid pattern and the second grid pattern and the periods of their corresponding parallel period directions are identical to each other, and the positions are matched and overlapped, so that both sides of the pair of arrangement period directions have the same characteristics as the respective parallel period directions. The deviation in the range of more than 1 / 4 period and less than 3 / 4 period of the parallel period corresponding to the arrangement period direction.

Description

technical field [0001] The present invention relates to a touch panel in which sensor electrodes for detecting touch positions are constituted by a mesh of fine lines. Background technique [0002] figure 1 and Figure 2A , 2B As a conventional example of this type of touch panel, the structure of a capacitive touch panel described in Japanese Patent Application Laid-Open No. 2017-103317 (published on June 8, 2017) is shown. This touch panel is configured such that a first conductor layer, an insulating layer, a second conductor layer, and a protective film are sequentially laminated on a transparent substrate 10 . exist figure 1 In , the part surrounded by the rectangular frame is the sensor area 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 sensor electrode is formed by the first conduct...

Problems solved by technology

[0014] However, since there is an insulating layer between the first conductor layer and the second conductor layer, the visual contrast of the second conductor layer is different from the visual contrast of the first conductor layer via the insulating layer. , there is a situation that the contrast of the sensor area cannot be completely eliminated in the existing touch panel
