1. A method for darkening a pixel by darkening a defective pixel on a display for controlling the application of a voltage to a corresponding pixel electrode by a thin film transistor disposed for each pixel, wherein:

  • a pixel electrode is formed on an insulating layer which is provided on an electrode of the thin film transistor, and the electrode of the thin film transistor and the pixel electrode are connected via a contact formed through the insulating layer; and

    a part of the pixel electrode is cut by a laser in the vicinity of the contact connecting an electrode of the thin film transistor to the pixel electrode to separate the contact from the pixel electrode and to thereby darken the corresponding pixel wherein the thin film transistor is not destroyed.
