DETECTION DEVICE
First Claim
1. A detection device, comprising:
- a substrate;
a detection electrode including;
a first electrode portion including;
a first thin wire extending at a first angle with respect to a first direction;
a second thin wire extending at a second angle different from the first angle with respect to the first direction; and
a first bent portion coupling the first thin wire and the second thin wire;
a second electrode portion adjacent to the first electrode portion in the first direction including;
a third thin wire extending at a third angle with respect to the first direction;
a fourth thin wire extending at a fourth angle different from the third angle with respect to the first direction; and
a second bent portion coupling the third thin wire and the fourth thin wire; and
a coupling portion including;
a fifth thin wire extending in the first direction and separated from the first bent portion and the second bent portion in a second direction crossing the first direction;
a sixth thin wire coupling the fifth thin wire and the first bent portion; and
a seventh thin wire coupling the fifth thin wire and the second bent portion;
a coupling wire coupled to the fifth thin wire of the coupling portion, and a protective layer covering the detection electrode and the coupling wire.

Abstract
According to an aspect, a detection device includes: a substrate; a detection electrode disposed on a plane parallel to a surface of the substrate and including conductive thin wires and electrical coupling portions disposed where the conductive thin wires intersect with each other or are bent, and are coupled with each other, the conductive thin wires being arranged in a mesh-like form; a coupling wire that couples the conductive thin wires with a detecting unit at an end portion of the detection electrode; and a protective layer that is made of an insulation material and that covers the detection electrode and the coupling wire. An area density of the conductive thin wires per unit area is smaller in an end region ranging from an electrical coupling portion closest to the coupling wire to the coupling wire than in a region of the entire detection electrode.
