Input detection device and electronic device
An input detection device is provided with a plurality of drive electrodes, a metal electrode opposed to the plurality of drive electrodes and having a predetermined wiring pattern, and a light-shielding film. In plan view, a width of the wiring pattern of the metal electrode overlapped with a portion of the light-shielding film with a large width is larger than a width of the wiring pattern of the metal electrode overlapped with portions other than the portion of the light-shielding film with the large width.
1. An input detection device comprising:
a plurality of drive electrodes;
a metal electrode opposed to the plurality of drive electrodes and having a predetermined wiring pattern; and
a light-shielding film, the light-shielding film having a portion of the large width the width of which is larger than other portions,
wherein, in plan view, a width of the wiring pattern overlapped with the portion of the large width is larger than a width of the wiring pattern overlapped with portions other than the portion of the large width.
2. The input detection device according to claim 1 ,
wherein the metal electrode is formed in a layer different from a layer in which the drive electrodes are formed.
3. The input detection device according to claim 1 ,
wherein the metal electrode is electrically connected to the drive electrodes.
4. The input detection device according to claim 1 ,
wherein the metal electrode is insulated from the drive electrodes.
5. The input detection device according to claim 1 , further comprising:
a spacer retaining a gap between a first substrate and a second substrate,
wherein, in plan view, the spacer is overlapped with the portion of the large width, and
the width of the wiring pattern overlapped with the spacer is larger than the width of the wiring pattern not overlapped with the spacer.
6. The input detection device according to claim 1 , further comprising:
a pixel array having a plurality of pixels of a red pixel, a green pixel, and a blue pixel disposed in a row-column configuration,
wherein, in plan view, the red pixel, the blue pixel, or both the red and the blue pixels are overlapped with the portion of the large width, and
the width of the wiring pattern overlapped with the red pixel, the blue pixel, or both the red and the blue pixels is larger than the width of the wiring pattern not overlapped with the red pixel, the blue pixel, or both the red and blue pixels.
