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.
