    Abstract: Disclosed is a light-emitting element including a first electrode, a first light-emitting layer, an ionic-liquid layer, a second light-emitting layer, and a second electrode. The first light-emitting layer is located over the first electrode and includes a first emissive polymer and an ionic liquid. The ionic-liquid layer is located over the first light-emitting layer and includes an ionic liquid. The second light-emitting layer is located over the ionic-liquid layer and includes a second emissive polymer and an ionic liquid. The second electrode is located over the second light-emitting layer. The light-emitting element may further include a first substrate under the first electrode, a second substrate over the second electrode, and a sealing layer located between the first substrate and the second substrate and surrounding the first electrode.

    Abstract: Provided are a fingerprint detection device and a display device that can reduce the occurrence of unintended patterns. The fingerprint detection device has a plurality of drive electrodes and a plurality of detection electrodes. The detection electrodes have a plurality of first line parts, a plurality of second line parts extending in a direction crossing the first line parts, and bent parts coupling the first line parts and the second line parts to each other. The drive electrodes have a plurality of electrodes arranged spaced apart from each other in a plan view, connecting parts coupling the electrodes adjacent to each other in the second direction to each other, and dummy electrodes in a floating state, each of the dummy electrodes being arranged between two electrodes arranged in the first direction between two detection electrodes.

    Abstract: According to one embodiment, a display device includes a first insulating substrate including a first substrate end, a second insulating substrate including an outer surface and a second substrate end, an electrode located between the first substrate end and the second substrate end, and a transparent conductive layer disposed on a side on which the outer surface is located. The outer surface includes a flat portion and a sloping portion. A thickness on a side on which the second substrate end is located is less than a thickness on a side on which the flat portion is located. The transparent conductive layer overlaps the sloping portion and is electrically connected to the electrode.
