1. A display apparatus comprising:

  • a lower panel including a pixel electrode in a pixel region defined by crossing gate and data lines;

    an upper panel including;

    a plurality of common electrodes, the plurality of common electrodes being separated from each other, the plurality of common electrodes together with the pixel electrode to form an electric field so as to display an image for a displaying driving mode, one or more of the plurality of common electrodes used to sense a capacitance change in accordance with a user'"'"'s touch for a touch sensing mode,a light-shielding portion for preventing light leakage,a first insulating layer on the plurality of common electrodes, the first insulating layer separating the plurality of common electrodes from each other,a touch wiring in a region overlapped with the light-shielding portion, the touch wiring electrically connected to the one or more of the plurality of common electrodes through the first insulating layer, anda second insulating layer on and in direct contact with both the first insulating layer and the touch wiring; and

    a liquid crystal layer of vertical alignment (VA) mode disposed between the upper panel and the lower panel, wherein the liquid crystal layer is changed in accordance with the electric field formed between the pixel electrode and the plurality of common electrodes.
