1. A display substrate comprising:

  • a substrate;

    a thin-film transistor (TFT) layer formed on the substrate, the TFT layer including a gate line, a data line electrically insulated from the gate line by a gate insulating layer and extended in a direction different from the gate line, a TFT electrically connected to the gate line and the data line, and a storage electrode formed in each pixel, wherein the storage electrode is formed from a same layer as the gate line;

    a color filter layer including a storage hole extending to a portion of the TFT layer corresponding to the storage electrode, the storage hole having a horizontal cross-sectional area greater than the storage electrode, wherein the horizontal cross-sectional area is measured in a plane parallel to the substrate; and

    a pixel electrode formed on the color filter layer and in the storage hole over the storage electrode to form a storage capacitor, the gate insulating layer being interposed between the pixel electrode and the storage electrode.
