Electrode substrate, display device, input device, and method of manufacturing electrode substrate

An input device,

• a first substrate including a first region, a second region and a third region, the second region arranged between the first region and the third region;
• a plurality of detection electrodes arranged in the first region, a plurality of first electrodes coupled to the detection electrodes respectively in the first region, each of the first electrode continuously formed from the first region to the third region in the first direction on the first substrate, each of the first electrodes including a plurality of concave/convex portions in the second region, each of the concave/convex portions including a first portion and a second portion, the first portion and the second portion arranged in the first direction, and a width of the first portion different from a width of the second portion in a second direction crossing to the first direction;
• and
• a protective film formed on the first electrode in the first region,
• wherein the protective film formed on first one of the concave/convex portions in the second region,
• wherein the protective film doesn't formed on second one of the concave/convex portions in the second region and the first electrode in the third region, the second one of the concave/convex portions is arranged nearer to the third region than the first one of the concave/convex portions,
• wherein a portion of each of the first electrodes in the third region is a pad, and is configured to output a detection signal from each of the detection electrodes.
