Structure for a parasitic capacitor and a storage capacitor in a thin film transistor-liquid crystal display and a method for making the same

摘要

The present invention includes a drain of the TFT which operates as a first upper electrode of the parasitic capacitor. A second upper electrode of the storage capacitor overlaps with the pixel electrode. An insulating layer is disposed between the second upper electrode and the pixel electrode. An insulating layer is also disposed between a first lower electrode of the parasitic capacitor at its associated upper electrode, as well as a second lower electrode of the storage capacitor and its associated upper electrode. Further, the overlapping direction of the two upper electrodes is identical with that of the two lower electrodes so that an undesired dc-offset voltage is made proportional between each of the pixels in the TFT-LCD array.
