Abstract:
1. A method of manufacturing a thin film transistor (TFT) substrate, comprising: forming a gate wiring and a capacitor dielectric layer on a substrate through a patterning process using one mask, the gate wiring comprising a gate electrode and a lower storage electrode, the capacitor dielectric layer being formed on the lower storage electrode; forming a gate insulation layer and an active layer on the substrate, the gate insulation layer having a first contact hole in a capacitor dielectric layer region, the active layer being formed on the gate insulation layer to cover the gate electrode; forming a data wiring comprising a source electrode, a drain electrode, and an upper storage electrode, the source and drain electrodes being disposed on the active layer such that the source and drain electrodes are spaced apart from each other, a portion of the upper storage electrode being disposed on the capacitor dielectric layer exposed through the first contact hole; forming a protection layer on the substrate; and forming a pixel electrode formed on the protection layer, the pixel electrode being connected to the drain electrode.
