1. A display device with a position input function, the display device comprising:
a pixel electrode;
a common electrode being above or below the pixel electrode;
a plurality of position detection electrodes defined by dividing the common electrode by a partition opening, the plurality of position detection electrodes and a position input body, that performs a position input, creating a capacitance therebetween, and the plurality of position detection electrodes detecting an input position input by the position input body;
a position detection line being below the common electrode and connected to one of the plurality of position detection electrodes, the position detection line including a first section being opposite the one of the plurality of position detection electrodes and a second section being opposite the partition opening;
a gate line extending parallel to the partition opening;
a switching element connected to the pixel electrode, the switching element including a gate electrode connected to the gate line; and
an electrode protruding from a side edge of the first section of the position detection line, at least a portion of the electrode not being opposite the partition opening, the electrode being below the common electrode and above the gate line, and at least a portion of the electrode being connected to the one of the plurality of position detection electrodes,
wherein the position detection line and the electrode are included in a lower layer than the common electrode and in an upper layer than the gate line.
