Sensor and sensor-equipped display device

A sensor-equipped display device comprising a display panel,

• the display panel comprising:
• control lines;
• signal lines;
• auxiliary lines;
• pixel electrodes;
• pixel switches each including a first switching element connected to one of the pixel electrodes, one of the control lines and one of the signal lines, and a second switching element connected to the one of the pixel electrodes, the one of the control lines and one of the auxiliary lines;
• a common electrode disposed in a display area and an outside of the display area, located under the pixel electrodes, and located above the control lines, the signal lines, the auxiliary lines and the pixel switches;
• a first circuit disposed outside the display area, connected to the control lines, supplying a drive signal to each of the control lines, and changing a state of the first switching element and the second switching element of each of the pixel switches to either of a first connection state and a second connection state;
• and
• a second circuit disposed outside the display area, and connected to the signal lines and the auxiliary lines,
• wherein
• each of the pixel electrodes is electrically connected to the corresponding signal line and electrically disconnected from the corresponding auxiliary line in the first connection state, and
• each of the pixel electrodes is electrically connected to the corresponding auxiliary line and electrically disconnected from the corresponding signal line in the second connection state.

A sensor comprising:
