Abstract: According to the present invention, a method for repairing a defective pixel of a liquid crystal display device is provided. The liquid crystal display device includes a first transparent substrate on an internal surface of which switching elements are formed; a second transparent substrate which is provided being spaced apart from the first transparent substrate and on an internal surface of which a black mask pattern is formed; liquid crystal interposed between the first and the second transparent substrates having a twisted-nematic orientation; and two polarizing plates provided on external surfaces of the first and the second transparent substrates. The method includes the steps of: applying a photosensitive resin composition containing a photosensitive resin and a colorant to the second transparent substrate on a light-outgoing side of the liquid crystal display device; irradiating light rays from an external light source so as to cure the resin composition at a position corresponding to that of a defective pixel on the polarizing plate on the light-outgoing side of the liquid crystal display device, the position being on optical paths of the light rays incident from the external light source; and removing an uncured resin composition from a surface of the polarizing plate on the light-outgoing side. According to the method of the invention, a light-shielding portion is easily formed at the position corresponding to that of the defective pixel by patterning.

Abstract: A liquid crystal display device and a method of compensating for a luminance point defect of the liquid crystal display device. After a detective luminance point pixel is detected, a laser beam is irradiated from an excimer laser oscillator on a portion of a surface of one of glass substrates of a liquid crystal panel on which an illuminating light is incident, the portion being located on the same irradiation path of the illuminating light with the luminance point pixel. In this way, the portion is laseretched, thereby forming a rough surface in the portion. When such a panel is used in a projection device, the light transmitted through the luminance point pixel is scattered and so reduced. Accordingly, the defective luminance point pixel is inconspicuous to normal pixels around the defective luminance point pixel.

Abstract: In a liquid crystal display device having pixels arranged in a matrix form, light is allowed to pass or blocked depending upon whether or not a voltage is applied to electrodes each corresponding to the pixels, and the display operation is conducted by controlling the transmission/nontransmission of light. When a conductor or switching element connected to an electrode is broken, it is not possible to apply such a voltage to the respective electrode. Such a pixel is always at the light transmission display state, with the result that the pixel becomes a bright spot, thereby degrading the display quality. Therefore, a blocking piece for blocking light is disposed over the pixel which becomes a bright spot. This prevents the bright spot from appearing, thereby improving the display quality.

Abstract: In an active liquid crystal display element which operates in a normally white mode, there is formed a shorting metal layer which overlaps each pixel electrode and a source bus adjacent thereto. In those portions of the pixel electrode and the source bus overlapping the shorting metal layer there are formed weld metal layers. The pixel electrode of a defective pixel is connected to the corresponding source bus by welding the weld metal layers and the shorting metal layer through irradiation with laser beams to the above-mentioned overlapping portions. As a result of this, the defective pixel becomes a black defect when the liquid crystal display element operates.

Abstract: The present invention provides a TFT structure and a repair method thereof, a GOA circuit. The TFT structure and the repair method thereof includes a source (10) having a plurality of independent U shape source branches (101). The drain (20) comprises a plurality strip drain branches (201). Each independent U shape source branch (101) is solely connected to a first metal line (30) with a connection part (103), and all the plurality of strip drain branches (201) are electrically coupled to a second metal line (40). The respective independent U shape source branches (101) and the corresponding strip drain branches (201) construct a plurality of independent source-drain conduction channels; as some independent U shape source branch (101) and the corresponding strip drain branch (201) are detected having a defect, the repair can be implemented by disconnecting the independent U shape source branch (101) and disconnecting the corresponding strip drain branch (201).
