1. An electrostatic capacitive touch panel comprising:
a first substrate;
a first electrode provided on the first substrate and extending in a first direction;
a first wiring line provided on the first substrate and connected to the first electrode;
a second substrate provided opposite the first substrate;
a second electrode provided on the second substrate and extending in a second direction that is perpendicular to the first direction;
a second wiring line provided on the second substrate and connected to the second electrode;
a plurality of third electrodes provided on the first substrate and extending in the first direction; and
a plurality of third wiring lines provided on the first substrate and connected to the plurality of third electrodes, wherein
the first wiring line includes a first extension portion,
the second wiring line includes a second extension portion,
the first extension portion and the second extension portion extend parallel to each other and in a non-parallel direction that is not parallel to the second direction,
the second electrode includes:
a first capacitance portion at least partially overlapping the first electrode in a plan view; and
a first connecting portion adjacent, in the second direction, to the first capacitance portion in the plan view, the first connecting portion having a smaller width in the first direction than does the first capacitance portion,
the second direction is positive when the first connecting portion is viewed from the first capacitance portion which is adjacent to the first connecting portion,
the second extension portion of the second wiring line is located in the positive second direction from the first extension portion of the first wiring line,
each of the plurality of third wiring lines includes an extension portion extending parallel to the first and second extension portions and extending in the non-parallel direction, and
the extension portion of each of the plurality of third wiring lines is separated from the second extension portion of the second wiring line by a greater distance than the first extension portion of the first wiring line.
