The plurality of sensing wide portions 33a are arranged at a constant interval along the second pixel direction DP2, and the plurality of sensing narrow portions 33b are between the two sensing wide portions 33a adjacent to each other in the second pixel direction DP2.

  As shown in FIG. 6, in the display device 100, since the touch panel 20 is stacked on the display panel 10, the grid electrode 21E is stacked on the square grid 12G of the black matrix 12.

  The first state in which the first pixel direction DP1 and the first electrode direction DE1 are parallel and the center of the square lattice 12G coincides with the center of the grid electrode 21E is the initial state in which the above-mentioned inclination angle θ is 0 ° It is. Further, in a plan view facing the sensing surface 31S, the position at which the center of the square lattice 12G in the initial state and the center of the grid electrode 21E overlap is the center C. The inclination angle θ is changed by rotating the grid electrode 21E about a rotation axis passing through the center C and extending along the direction in which the display panel 10 and the touch panel 20 are stacked. In the grid electrode 21E, the unit length in the unit grid 21c is the electrode pitch PE.

When the pixel density is 96 ppi, the pixel pitch PP is 0.2645 mm, and when the pixel density is 150 ppi, the pixel pitch PP is 0.1693 mm, and when the pixel density is 364 ppi, the pixel pitch PP is It is 0.0698 mm. Each pixel pitch PP is a value obtained by dividing 1 inch, that is, 25.4 mm by each pixel density.

  Hereinafter, the relationship between the configuration of the display device 100 and moire generated in the display device 100 will be described. In the configuration of the display device 100, when each of the pixel density of the black matrix 12, the electrode pitch PE, and the inclination angle θ is set to a predetermined value, whether or not moiré occurs on the operation surface of the touch panel 20 The scale is visually evaluated.

  First, evaluation results when the pixel density of the black matrix 12 is 96 ppi are as shown in Table 1 below. In the table shown below, the pixel / electrode is a value obtained by dividing the pixel pitch PP by the electrode pitch PE, and the electrode / pixel is a value obtained by dividing the electrode pitch PE by the pixel pitch PP. Further, in the table shown below, a case where no moiré is recognized on the operation surface of the touch panel 20 is indicated by ○, a case where moiré is recognized is indicated by x, and moiré is recognized but the moiré is suppressed. The case is indicated by △.

  As Table 1 shows, when the inclination angle θ is 30 ° or more and 35 ° or less, or 55 ° or more and 60 ° or less, the electrode pitch PE is 0.300 mm or more and 0.355 mm or less, or 0.410 mm or more It is recognized that moiré does not occur if it is 0.450 mm or less. That is, it is recognized that no moiré occurs if the ratio of the pixel pitch PP to the electrode pitch PE is 0.5878 or more and 0.6451 or less, or 0.7451 or more and 0.8817 or less. In addition, it is recognized that no moiré occurs if the ratio of the electrode pitch PE to the pixel pitch PP is 1.2170 or more and 1.4402 or less, or 1.6633 or more and 1.8256 or less.

However, in these configurations, the range which is permitted for the electrode pitch PE is small in order to obtain a structure in which no moiré occurs, in other words, the allowable range for the amount of deviation from the optimum electrode pitch PE is small. Therefore, it is preferable that one of the ranges described above be selected for the electrode pitch PE at each inclination angle θ.

If the inclination angle θ is 30 ° or more and 40 ° or less, or 50 ° or more and 60 ° or less, the electrode pitch PE where no moiré occurs as compared to the case where the inclination angle θ is a value included in other ranges.

That is, when the ratio of the pixel pitch PP to the electrode pitch PE is 0.5375 or more and 0.5461 or less, or 0.5643 or more and 0.5739 or less, or 0.6270 or more and 0.6389 or less, moiré can be suppressed.

It is also recognized that the wide range of the above is wide, that is, generation of moire on the operation surface of the touch panel 20 can be suppressed.
The evaluation results when the pixel density of the black matrix 12 is 364 ppi are as shown in Table 3 below.

  As Table 3 shows, when the inclination angle θ is 30 ° or more and 35 ° or less, or 55 ° or more and 60 ° or less, moire occurs if the electrode pitch PE is 0.260 mm or more and 0.265 mm or less It is recognized that there is no. That is, if the ratio of the pixel pitch PP to the electrode pitch PE is 0.2634 or more and 0.2685 or less and the ratio of the electrode pitch PE to the pixel pitch PP is 3.7249 or more and 3.7966 or less, moire occurs.

It is also recognized that the wide range of the above is wide, that is, generation of moire on the operation surface of the touch panel 20 can be suppressed.

  Further, from the evaluation results shown in Tables 1 and 2 described above, in the display device 100, each of the pixel density, the electrode pitch PE, and the inclination angle θ is included in the range defined in the following Table 4. It is recognized that moiré can be suppressed on the operation surface of the touch panel 20 in the case of

Note that the above-described embodiment can be implemented with appropriate modifications as follows.
The values of the pixel pitch PP when the pixel density is 96 ppi, 150 ppi, and 364 ppi are not limited to the values described above. The point is that if the pixel density is 96 ppi, the black matrix 12 may have a configuration capable of arranging 96 pixels in 1 inch, and if the pixel density is 150 ppi, the black matrix 12 may be It may be any configuration as long as 150 pixels can be arranged in one inch.

A resist layer is formed. Next, the thin film layer is processed into a plurality of sensing electrodes 33 by a wet etching method using ferric chloride or the like to obtain a first film. Further, as in the case of the sensing electrode 33, a thin film layer formed on another resin film functioning as the transparent substrate 34 is processed into a plurality of drive electrodes 32, whereby a second film is obtained.
