Conduction defect correcting method for liquid crystal display device and manufacturing method thereof

The present invention relates to a method for correcting a conduction defect in a liquid crystal display device and a manufacturing method of the liquid crystal display device using the method, particularly to a method of correcting a conduction defect on a conducting part, which is provided between substrates in a liquid crystal panel. In a liquid crystal panel, a scanning electrode is formed on an upper substrate, and a scanning electrode terminal, a data electrode, and a data electrode terminal are formed on a lower substrate. The scanning electrode and the data electrode are opposed to each other via a liquid crystal material. Conducting members which are disposed in a sealing member and have conductivity are sandwiched between the scanning electrode and the scanning electrode terminal. Ac voltage is applied from the scanning electrode terminal and the data electrode terminal so as to apply ac voltage between the scanning electrode and the scanning electrode terminal via the data electrode and the liquid crystal material, thereby correcting a conduction defect on the conducting part. This method makes it possible to correct a conduction defect on a conducting member in a liquid crystal display device, which is provided with the conducting part between the substrates, so as to improve display quality and a yield of the liquid crystal display device.
