  • Publication number: 20200242992
    Abstract: A display device comprises a display substrate, first interconnections, second interconnections, a driving circuit and a polarizing plate. The display substrate includes a bend portion which is curved with respect to an axis parallel to a first direction. The first interconnections extend in the first direction and are on the display substrate. The second interconnections are on the display substrate, connected to the first interconnections and extend in a second direction different from the first direction. The driving circuit is electrically connected to the first interconnections and the second interconnections and provides driving signals to the first interconnections and the second interconnections. The polarizing plate is on the display substrate and overlaps the first interconnections and the second interconnections.
