Patent ID: 7915614

Claim:
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 plurality of storage holes exposing a portion of the TFT layer corresponding to the storage electrode, the storage holes having horizontal cross-sectional areas greater than the storage electrode, wherein the horizontal cross-sectional areas are 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, wherein the color filter layer comprises a red color filter, a green color filter and a blue color filter formed in each pixel, and opening widths of the storage holes formed in each of the red, green and blue color filters are different from each other.
