A displaying device at least comprises a thin film transistor (TFT); a first electrode controlled by the TFT; a first capacitor electrode and a second capacitor electrode electrically connected to each other through the first electrode. The first electrode has a first slit. The first slit is positioned between a first zone and a second zone, wherein the first zone connects the first capacitor electrode and the first electrode, and the second zone connects the second capacitor electrode and the first electrode. If a defect is observed, a portion of the first electrode is removed for isolating the first capacitor electrode and the second capacitor electrode.
