Embodiment approach 1

[0026] The input device X1 according to the first embodiment of the present invention will be described. The input device X1 is a capacitive touch panel.

[0027] like figure 1 As shown, the input device X1 has an input area E for inputting information by the user's finger operation or the like I , and in input area E I the outer side of the outer region E o . In addition, in the outer region E o The external conduction region E is the region that is electrically connected to the FPC (Flexible Printed Circuit) outside the figure. G .

[0028] Input device X1 such as Figure 1 to Figure 4 As shown, the base body 10 , the first detection electrode pattern 20 , the second detection electrode pattern 30 , the insulator 40 , and the detection wiring 50 are provided.

[0029] base 10 such as image 3 (a) and image 3 As shown in (b), it has a main surface 10a. Although the shape in plan view of the base body 10 is, for example, a rectangular shape, it is not limited to th...

Embodiment approach 2

[0056] Next, the input device X2 according to the second embodiment of the present invention will be described. The input device X2 is, like the input device X1, a capacitive touch panel.

[0057] Image 6 is a diagram representing the input device X2, and is the figure 1 The I-I corresponding cross-sectional view. Figure 7 is an enlarged representation Image 6 R 2 Part of the diagram is a diagram for explaining a change in the inclination angle θ of the insulator 40 with respect to the main surface 10 a of the base body 10 . also, Figure 7 The inclination angle θ of each part of the insulator 40 is the angle formed by the tangent line and the main surface 10 a of the base body 10 when a tangent line is drawn at each part of the insulator 40 .

[0058] In the input device X2, such as Figure 7 As shown, the inclination angle θ of the insulator 40 with respect to the main surface 10a of the base body 10 has a minimum value and a maximum value between the end portion 4...

Embodiment approach 3

[0061] Next, the input device X3 according to the third embodiment of the present invention will be described. The input device X3 is, like the input devices X1 and X2, a capacitive touch panel.

[0062] Figure 8is a diagram representing the input device X3, and is the figure 1 The I-I corresponding cross-sectional view. Figure 9 is an enlarged representation Figure 8 A plan view of the main part of the input device X3.

[0063] In the input device X3, such as Figure 8 As shown, in the cross section along the second detection electrode pattern 30 , the thickness L1 of the second connection electrode 32 in the second detection electrode pattern 30 located at the end portion 42 of the insulator 40 is larger than that of the second detection electrode pattern 30 located at the top 41 of the insulator 40 Thickness L2 of the second connection electrode 32 in the electrode pattern 30 . Therefore, even if stress is applied to the second connection electrode 32 located at th...

Abstract

An input device is provided with a substrate having a main surface, a first detecting electrode pattern provided upon the main surface of the substrate, and a second detecting electrode pattern provided upon the main surface of the substrate wherein a portion intersects the first detecting electrode pattern through an insulator; wherein the insulator, in cross-section taken along the second detecting electrode pattern, comprises a curved convex surface in a region from an end portion to the top portion of the insulator.

Description

technical field [0001] The present invention relates to an input device that detects a place where a user has performed an input operation as an input position, and a display device including the same. Background technique [0002] For example, a conventional input device such as a capacitive touch panel includes a base body, a first detection electrode pattern provided on the main surface of the base body, and a second detection electrode pattern provided on the main surface of the base body, And it crosses the 1st detection electrode pattern (for example, refer patent document 1). [0003] In such an input device, an insulator for electrically insulating the first detection electrode pattern and the second detection electrode pattern is provided between the first detection electrode pattern and the second detection electrode pattern. That is, the insulator is provided on the main surface of the base body so as to cover a part of the first detection electrode, and a part o...
