摘要:
A display substrate includes a thin-film transistor (TFT) layer, a color filter layer and a pixel electrode formed on a substrate. The TFT layer includes a gate line, a data line electrically insulated from the gate line and extending 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 from the same layer as the gate line in each pixel. The color filter layer includes a storage hole extending to a portion of the TFT layer corresponding to the storage electrode. The storage hole has 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. The pixel electrode is formed on the color filter layer and in the storage hole to form a storage capacitor with the storage electrode.
