Abstract: A display device includes a plurality of signal lines disposed on an upper surface of a first substrate and electrically connected to a display unit, a plurality of link lines disposed below the first substrate, a plurality of polymer patterns disposed on a side surface of the first substrate and connecting each signal line and each link line to each other, and a plurality of side lines electrically connecting the plurality of signal lines and the plurality of link lines and disposed on the plurality of polymer patterns to overlap each polymer pattern. As such, the bezel area is narrow and the polymer pattern can suppress the migration of the metal component generated in the side line and improve the adhesive force of the side line. Further, the reliability of the display device is improved and a wiring line pattern with a narrow pitch can be formed.
