Abstract:
The pixel structure and the repairing method of the TFT array substrate are provided. The pixel has a semiconductor electrode which is partially overlapped with a floating metal located in the first conductive layer. Both the data line and the drain electrode have protruded regions partially overlapped with the semiconductor electrode and the floating metal. Once the pixel is found to be a white defect, a laser beam is used to irradiate the protruded region of the data line to electrically connect the data line and the floating metal and so as to form a diode structure having the rectified effect. Consequently, after the laser repair, the pixel defect will display as the non-flicked white point and black point in the white-picture inspection and the black-picture inspection respectively.

Abstract:
A liquid crystal panel includes a pair of glass substrates and, and a liquid crystal layer provided therebetween. In a surface at a side opposite from the liquid crystal layer in the glass substrate, a recessed part is formed at a position corresponding to a foreign substance (bright spot defect portion). A light shielding layer which shields light is formed in the recessed part. Accordingly, when comparing with the case where a light shielding layer is formed on the surface of a glass substrate as conventional display, a distance between the light shielding layer and the foreign substance can be made short, and thereby, the light shielding range by the light shielding layer can be made larger than a conventional display.

Abstract:
A method of correcting a defective pixel of a liquid crystal display by scanning the defective pixel with a laser beam. The liquid crystal display is moved to let the defective pixel face a lens which converges the laser beam. The laser beam is relatively moved to the lens in a direction orthogonal to the optical axis of the laser beam to scan the defective pixel.
