Abstract: A display apparatus includes a display panel (DP) and a sensor unit on the DP. The sensor unit includes: a first conductive layer (CL) including a first bridge (FB); a second CL disposed on the first CL, the second CL including first sensor portions (FSPs) spaced apart from each other and arranged in a first direction; a first insulating layer (IL) disposed between the first CL and the second CL, the first IL including through-holes (THs) extending between the FB and the FSPs overlapping the FB; and contact electrodes (CEs) filling spaces defined by a bridge top surface of the FB exposed by the THs, insulating sidewalls of the first IL defining the THs, and sensor bottom surfaces of the FSPs facing the FB. A cross-section, which is perpendicular to a top surface of the DP, of each of the CEs has a polygonal shape of five or more sides.

Abstract: A display device may include a display panel, an input sensing unit, and a driving circuit board. The display panel includes a base substrate and a driving pad, and the input sensing unit includes an encapsulation substrate and an input pad. The driving circuit board may be provided on one of side surfaces of the base substrate adjacent to the driving pad and on one of connection surfaces of the encapsulation substrate adjacent to the input pad and may be electrically connected to the driving pad and the input pad, respectively.
