Abstract: A touch panel includes: a base member having a folding axis which extends in a first direction, a folding area including the folding axis, and a non-folding area adjacent to the folding area; a touch cell which senses an external touch signal, and at least a part of which overlaps the folding area; a pad disposed on the base member, and disposed to be spaced apart from the touch cell when viewed in a plane; and a first driving wiring having a first part and a second part, wherein at least the first part extends in a diagonal direction with respect to a direction in which the folding axis extends, and which connects the pad and the touch cell. At least a part which extends in the diagonal direction overlaps the folding area.

Abstract: A fingerprint sensing unit includes a substrate; a buffer layer disposed on the substrate; a thin film transistor disposed on the buffer layer; an insulating layer disposed on the buffer layer and that has an opening that exposes at least a portion of the buffer layer; and a sensing electrode disposed on the portion of the buffer layer that is exposed by the opening, where the sensing electrode is connected to the thin film transistor. A display device that includes the fingerprint sensing unit can reduce internal reflection of external light

Abstract: A touch panel is manufactured by a method that decreases undesirable reflections of external light while improving the visibility of emitted light. The touch panel includes a base layer including an active region responsive to an external touch to generate an electronic signal and a peripheral region adjacent to the active region, and a first conductive pattern disposed on the active region and a second conductive pattern disposed on the peripheral region, each of the first conductive pattern and the second conductive pattern including a conductive layer having an external light reflectivity and a darkening layer disposed over the conductive layer. External light reflectivity of each of the first and second conductive patterns is lower than that of the conductive layer.
