摘要： Laser beam irradiation spots are formed in a delta arrangement on a defective pixel present in a liquid crystal panel so that liquid crystal molecules in areas surrounding the irradiation spots are oriented vertically. Alternatively, an aligning film in a defective pixel is irradiated with a laser to form minute grooves in a different direction than the rubbing direction of the aligning film, whereby the orientation of the liquid crystal is changed so that the liquid crystal between the aligning films is no longer twisted. Thereby, a defective pixel present in a liquid crystal display panel can be made inconspicuous, and as a result, degradation of the display quality of the liquid crystal display device after correction can be prevented.
摘要翻译：激光束照射点以存在于液晶面板中的缺陷像素上的delta布置形成，使得围绕照射点的区域中的液晶分子垂直取向。或者，用激光照射缺陷像素中的取向膜，以在与取向膜的摩擦方向不同的方向上形成微小的槽，由此改变液晶的取向，使得取向膜之间的液晶为不再扭曲。由此，能够使存在于液晶显示面板的缺陷像素不显眼，能够防止校正后的液晶显示装置的显示品质的劣化。

摘要： A display panel drive circuit includes a shift register constructed of unit circuits connected in stages. The unit circuits generate signal line selection signals, respectively, which signal line selection signals are made active for a respective certain period of time to form a respective pulse, and the pulses are outputted successively from respective unit circuits in order of ordinal number starting from a first stage until an end stage. In at least one embodiment, each of the unit circuits receive (i) clock signals generated based on a sync signal received from outside of the display panel drive circuit, (ii) a start pulse signal generated based on the sync signal, or a signal line selection signal generated in a stage different from its own stage, and (iii) a clear signal. The clear signal is made active in a case where anomalousness is included in the sync signal, and no pulse is outputted from the shift register until a subsequent vertical scanning period starts. This configuration achieves a display panel drive circuit which prevents display disorder or holds down increase in load given to a power source, each of which occurs in a case where anomalousness is included in the sync signal.

摘要： Provided is a liquid crystal display device performing a precharge and having a function of switching an order for selecting scanning lines, in which such as flicker and burn-in can be prevented from being produced. A scanning line drive circuit selects scanning lines either in ascending order or in descending order based on an order of arrangement according to a shift direction signal, and causes selection periods of the scanning lines to be partially overlapped for a precharge. A data line drive circuit applies voltages of different polarities to data lines by frame and by data line. A common voltage generating circuit generates two types of voltages whose levels are independently adjustable, selects one of the two voltages according to a scan selection signal and applies the selected voltage to a common electrode of a liquid crystal panel. As the common voltage generating circuit, a D/A converter may be used.
