Abstract: A foldable display device includes a display panel having a bent display portion and a non-bent display portion, and a touch sensing unit provided on the display panel and including a bent touch portion and a non-bent touch portion. The touch sensing unit includes a plurality of sensing electrodes, and each of the sensing electrodes comprises a conductive material having a porous structure. The porous structure resists cracking and the resulting sensing electrodes may have an optical anisotropy. Thus, the sensing electrodes may perform a polarizing function to eliminate need for a separate polarizer.
