A device for manufacturing an active matrix substrate including a plurality of pixels arranged in a matrix, in which a short-circuit defect in the active matrix substrate is detected and repaired, includes a stage (30a) configured to place a test substrate (19) which will become the active matrix substrate, a defective pixel detector (40a) configured to input a test signal to the test substrate (19) placed on the stage (30a), and electrically detect coordinates of a defective pixel in which a short-circuit defect has occurred, and a defect position identifier (50) configured to input the test signal to the test substrate (19) placed on the stage (30a) to cause the defective pixel detected by the defective pixel detector (40a) to generate heat, and sense the heat generation in the defective pixel using far-infrared thermography, thereby identifying a position of the short-circuit defect in the defective pixel.
摘要:
In an active matrix substrate having thereon a matrix of pixels each composed of a pair of a TFT and a pixel electrode, when the shorting of the pixel electrodes in adjacent pixels occurs, an electrical connection between the pixel electrode and drain electrode in the TFT of a matching pair in either of the shorted pixel electrodes is cut. For example, when the shorting of two adjacent pixels occurs, the pixel electrodes in both the pixels are driven by the TFT in the non-cut pixel. This arrangement makes it possible to make a display defect resulted from the shorting of adjacent pixels on the active matrix substrate less noticeable, and hence to upgrade display quality.

A method for growing a silicon carbide single crystal on a seed crystal using a molecular beam source in vacuo by means of a molecular beam epitaxy, wherein a material in the molecular beam source is silicon carbide. A silicon molecular beam source and/or an impurity molecular beam source for doping may be further used. Temperatures of the silicon carbide molecular beam source, the silicon molecular beam source, the impurity molecular beam source and the seed crystal are independently controlled. Vapor compositions are controlled by the silicon carbide molecular beam source, the silicon molecular beam source and the impurity molecular beam source.
