A display device with a position input function includes a pixel electrode, a common electrode, position detection electrodes, a position detection line, a pixel connection line, and a shield electrode. The common electrode is overlapped with the pixel electrode on an upper layer side or a lower layer side. The position detection electrodes are formed by dividing the common electrode by a partition opening and form a capacitance with a position input body and detect an input position. The position detection line is arranged on an upper layer side or a lower layer side with the common electrode and connected to the position detection electrode. The pixel connection line extends in parallel with the partition opening and is connected to the pixel electrode. The shield electrode extends overlapping with the partition opening and is on a same layer as the position detection line and connected to the position detection line.
