1. A sensor device, comprising:
- a detection electrode including an electrode pattern having conductive line fragments arranged on a detection surface, the detection electrode configured to detect a contact or approach of an object to the detection surface; and
a driving electrode configured to form a capacitance between the detection electrode and the driving electrode, whereineach of the line fragments includes a metal material that blocks light,the driving electrode is formed of a transparent conductive material that is different from the metal material,the driving electrode is disposed in a layer different from the detection electrode in a normal direction of the detection surface to be opposed to the detection electrode with a dielectric intervening between the detection electrode and the driving electrode,the electrode pattern has a plurality of connection points at which ends of the line fragments are connected to each other, and at least part of the connection points is arranged linearly such that an arrangement gap thereof in a first direction is set to a first connection point pitch and an arrangement gap thereof in a second direction is set to a second connection point pitch, the first direction being different from the second direction,a plurality of unit pixels are defined with a first unit pitch in the first direction and a second unit pitch in the second direction,the first connection point pitch is defined to exclude a range from 0.5×

Abstract
A sensor-equipped display device is provided and includes a display panel and a detection electrode. The panel includes a display area in which pixels are arranged with a first pixel pitch in a first direction and a second pixel pitch in a second direction. The electrode includes an pattern having line fragments. The pattern has connection points at which ends of the fragments are connected to each other, and at least part of the connection points is arranged linearly such that an arrangement gaps thereof in the first and second direction is set to a first and second connection point pitch.
