1. A thin-film transistor array substrate comprising:

  • a thin-film transistor comprising an active layer, a gate electrode, a source electrode, and a drain electrode;

    a lower electrode of a capacitor formed of the same layer as the active layer;

    an upper electrode of the capacitor formed on the lower electrode;

    a first insulation layer formed between the lower and upper electrodes, and formed between the active layer and the gate electrode, wherein a gap is formed outside the lower electrode;

    a second insulation layer formed on the first insulation layer and having the same etching surface as the first insulation layer in the gap;

    a bridge formed of the same material as at least one of the source and drain electrodes, wherein the bridge at least partially fills the gap;

    a pixel electrode formed of the same material as the upper electrode; and

    a third insulation layer covering the source and drain electrodes, wherein an opening is defined in the third insulation layer, and wherein at least part of the pixel electrode is formed in the opening.
