摘要： A liquid crystal display device includes: pixel electrodes arranged in columns and rows, each including a reflective electrode region; scanning lines; and signal lines. The device sequentially supplies a scanning signal voltage to one of the scanning lines after another to select one group of pixel electrodes, connected to the same one of the scanning lines, after another, and then supplies display signal voltages to the selected group of pixel electrodes by way of the signal lines, thereby displaying an image thereon. The pixel electrodes are arranged such that the polarity of a voltage to be applied to a liquid crystal layer is inverted for every predetermined number of pixel electrodes in each of the rows and in each of the columns. The display signal voltage to be supplied to each pixel electrode is updated at a frequency of 45 Hz or less.

摘要： Each signal line enters a preliminary polarity inversion period prior to a normal polarity inversion period so as to be inverted to the opposite polarity. By the preliminary polarity inversion a signal line on a border of blocks experiences a potential hike and the potential oscillates, which, however, is restored later by the application of a correct potential in the normal polarity inversion period. When transferring data per block, the problem of different potential states between the border of the blocks and an area surrounding it, which is caused by the potential oscillation of the signal line on the border of the blocks, is relieved.

摘要： In an image display device which employs pulse width modulation driving, a voltage which is less than a voltage supplied to signal lines is applied to pixel electrodes. Tones are displayed by shifting phases of waveforms of the signal lines and scanning lines, and polarities of pixels in a signal line direction are inverted alternately. This prevents increase in power consumption which is caused by pulse intervals which become too small at high tone levels, in addition to preventing change in tone level due to external factors such as temperature, or signal delays in a driver or wiring.

A method for fabricating a liquid crystal display device according to the present invention includes the steps of: providing an LCD panel that includes a photopolymerizable compound in its liquid crystal layer; and forming alignment sustaining layers by polymerizing the photopolymerizable compound in the liquid crystal layer of the LCD panel with the liquid crystal layer irradiated with light and supplied with a voltage simultaneously. The step of forming the alignment sustaining layers includes the steps of: i) applying a predetermined voltage between a pixel electrode and a counter electrode while a switching element is in ON state; and ii) changing the voltage at a storage capacitor counter electrode into a voltage, of which the polarity is opposite to a voltage at the storage capacitor counter electrode in the step i), after the switching element in ON state has been turned OFF.

摘要： A method of driving source lines is arranged as follows: One output signal line S61 of a source driver is connected to a plurality of lines corresponding to respective source lines SR7 through SB12, and these source lines from SR7 (starting data line) to SB12 (terminating data line) are grouped as one block (group). In each block, a signal voltage of a divided output is supplied to the source lines during a first horizontal period T, while a signal voltage whose polarity is opposite to that of the aforesaid output is supplied to the source lines in a second horizontal period that is after the first horizontal period. In each of the horizontal periods, the source lines SR7 through SB12 are subjected to sequential selection. In addition to this, the source line SB12 is selected before turning the source line SR7 off. With this, a method of driving source lines, which can restrain (eliminate) the voltage variation on each source line and pixel electrode on account parasitic capacities between source lines, can be realized.
