Abstract
An input device includes a first substrate, a first light-emitting element unit, and a third electrode unit. The first substrate has a first surface and a second surface. The first light-emitting element includes a first electrode unit formed on the second surface, a second electrode unit formed in a layer different from that of the first electrode unit, and a luminescent layer electrically in contact with at least a part of the first electrode unit and a part of the second electrode unit, and formed between the first electrode unit and the second electrode unit. The third electrode unit is insulated from the first electrode unit and detects a change in an electric field between the first electrode unit and the third electrode unit depending on coordinates of a proximity object present at a position overlapping with the first surface in planar view.
