Abstract: A display device is disclosed that includes a substrate, a display portion, a conductive layer, an inorganic layer, and an amorphous silicon layer. The substrate includes a first area including a transmission area and a non-transmission area adjacent to the transmission area, and a second area adjacent to the first area. The display portion is disposed in the non-transmission area and the second area on the substrate. The conductive layer is disposed between the substrate and the display portion, and overlaps the non-transmission area and the second area. The inorganic layer is disposed on the substrate under the conductive layer, in contact with the conductive layer, and overlaps the conductive layer. The amorphous silicon layer is disposed on the substrate, under the inorganic layer, in contact with the inorganic layer, overlaps the conductive layer in the first area, and entirely overlaps the substrate in the second area.

Abstract: A display device includes a display panel displaying an image, a circuit board coupled with the display panel, and a metal pattern electrically connecting the display panel and the circuit board. The display panel includes a base layer and a circuit layer disposed on the base layer and including a pad electrode exposed to an outside via an opening defined through the base layer. The metal pattern includes a first portion overlapping the opening and being in contact with the pad electrode and a second portion that does not overlap the opening and is in contact with the circuit board.
