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.

Abstract: According to one embodiment, a display device includes a display panel including a display area and a non-display area including a first area and a second area. The display panel includes a first substrate, a second substrate including a contact hole crossing a borderline, a protection layer provided over the display area and the first area, and a connecting material. An outer edge of the protection layer includes one first outer edge located on the borderline, another first outer edge located on the borderline opposed to the one first outer edge across the contact hole, and a second outer edge provided in the first area, connected to an end of the one first outer edge and extending along the contact hole.
