An input device includes a first substrate, a light-emitting element, and a third electrode unit. The first substrate has first and second surfaces. The light-emitting element unit includes: a first conductive electrode unit including first conductive layers; a second conductive electrode unit including second conductive layers each having a size overlapping with the first conductive layer in planar view; and luminescent layers conducted with at least a part of the first electrode unit, each provided between the first and second electrode units and conducted with the first conductive layer and the second conductive layer overlapping with the first conductive layer in planar view. The third electrode unit is insulated from the first conductive layers and detects a change in an electric field between the first conductive layers and the third electrode unit depending on coordinates of a proximity object at a position overlapping with the first surface in planar view.
