Abstract: A display device includes a touch panel (TP), a transparent adhesive member (TAM) on a surface of the TP, a touch printed circuit board (TPCB), and a display panel (DP) on a surface of the TAM. The TP includes a sensing portion and a pad side portion (PSP) on a side of the sensing portion. The TPCB includes a contact portion (CP) attached to a surface of the PSP. The DP includes a substrate, an optical film (OF) on a surface of the substrate, and a bending protection layer (BPL) on a side of the OF on the surface of the substrate. The surface of the PSP includes a connection area attached to the CP and a non-connection area not attached to the CP. The OF is spaced from the BPL with a gap disposed therebetween. The TAM overlaps, in a thickness direction, with the TPCB and the gap.

Abstract: An organic light emitting display device may include a substrate having a display area and a non-display area at least partially surrounds the display area, a pixel structure disposed in the display area on the substrate, a via insulating layer disposed in the non-display area on the substrate and having a contact hole, a lower pad disposed on the via insulating layer and a connecting structure. Here, the connecting structure may include a flexible substrate disposed on the lower pad, an upper pad disposed between the flexible substrate and the lower pad, and an upper dummy pad spaced apart from the upper pad in a first direction on a bottom surface of the flexible substrate.
