Abstract: A third metal wire, a common power supply line, a sensor power supply line, a selector switch 58, and a shield portion are provided. The third metal wire is provided on a first sensor electrode formed in a display region of an array substrate. The common power supply line and the sensor power supply line are provided in a peripheral region of the array substrate. The selector switch 58 is configured to supply either DC common voltage or AC sensor voltage to the first sensor electrode. The shield portion has a mesh shape. The shield portion is provided above the sensor power supply line. The shield portion is formed using the same material as the third metal wire.
