Abstract: A display device includes a display panel including a first signal pad portion including first signal pads, a second signal pad portion including second signal pads, and a first dummy pad portion disposed between the first signal pad portion and the second signal pad portion and including at least one first dummy pad, and a flexible circuit board including a first terminal portion including first terminals, a second terminal portion including second terminals, and a first cut portion disposed between the first terminal portion and the second terminal portion. The flexible circuit board is compressed to the display panel. The first terminals are electrically connected to the first signal pads. The second terminals are electrically connected to the second signal pads. The first cut portion overlaps the first dummy pad portion.

Abstract: A display device includes a substrate including a bending area, a flat area adjacent to the bending area, and first and second surfaces opposite to each other, a display unit corresponding to the flat area and on the first surface, a support layer which is on the second surface of the substrate, corresponds to the flat area, and is disconnected at the bending area to define an end portion closest to the bending area, and the substrate defining a groove in the bending area. The end portion of the support layer is bendable together with the substrate and includes a flat portion corresponding to the flat area of the substrate, and a bending portion corresponding to the bending area of the substrate. The substrate which is unbent disposes the bending portion having an acute angle of inclination with respect to the second surface of the substrate.
