Claim:
1. A display device, comprising: a substrate; a plurality of pixels arranged in a first region on a first main surface side of the substrate; light-shielding portions surrounding the plurality of pixels so as to demarcate each of the plurality of pixels in the first region; a plurality of first electrodes each of which is provided in each of the plurality of pixels; a second electrode provided so as to overlap the plurality of first electrodes when seen in a plan view; a plurality of third electrodes provided at intervals so as to respectively overlap the second electrode when seen in a plan view; and a fourth electrode provided apart from any of the plurality of third electrodes in the first region, wherein images are displayed by applying voltage between each of the plurality of first electrodes and the second electrode, wherein input positions are detected based on electrostatic capacitance between the second electrode and each of the plurality of third electrodes, wherein each of the plurality of third electrodes includes a first metal layer or a first alloy layer, wherein the fourth electrode includes a second metal layer or a second alloy layer, wherein a ratio of total sum of areas of portions of the plurality of pixels which overlap any of the plurality of third electrodes and the fourth electrode when seen in a plan view to a total sum of areas of the plurality of pixels is 1 to 22%, and wherein an area of a respective one of the pixels does not include an area of the light-shielding portion demarcating the respective one of the pixels.
