Abstract: Disclosed is a display device having a first light-emitting element and a second light-emitting element. The first light-emitting element and the second light-emitting element each possess: a first electrode; a second electrode over and in contact with the first electrode; an electroluminescence layer over the second electrode; and a third electrode over the electroluminescence layer, the third electrode being shared by the first light-emitting element and the second light-emitting element. The first electrode of the first light-emitting element and the first electrode of the second light-emitting element respectively include a first metal and a second metal different from the first metal.

Abstract: First electrodes are formed on an insulation surface in such a manner that the adjacent first electrodes are connected in a first direction and are separated in a second direction intersecting the first direction. Second electrodes are formed on an insulation surface in such a manner that the adjacent second electrodes are connected in the second direction and are separated in the first direction. Third electrodes are formed in regions in which the third electrodes overlap with the first electrodes and do not overlap with the second electrodes in such a manner that the adjacent third electrodes are connected in the second direction and are separated in the first direction. A flexible insulation layer is formed between the first electrodes and the third electrodes. An area of each of the third electrodes is less than an area of each of the first electrodes.

Abstract: A touch sensor includes first electrodes which are driving electrodes of the touch sensor, second electrodes which are detecting electrodes of the touch sensor, third electrodes, and an insulating film which is stacked on the first electrodes. Each of the first electrodes extends in a first direction. Each of the second electrodes and each of the third electrodes are formed on the insulating film, and extend in a second direction. The second electrodes overlap with partial regions of the first electrodes, and the third electrodes overlap with other partial regions of the first electrodes and are formed in gaps between the second electrodes. A film thickness of the insulating film between the first electrodes and the third electrodes varies due to pressing force in a film thickness direction, and the insulating film constitutes the electrostatic capacitance-type pressure sensor with first electrodes and the third electrodes.
