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： One embodiment of the present invention provides a liquid crystal display device in which auxiliary capacitance lines are driven, thereby allowing the range of drive voltage to be kept narrow while increasing the difference between the maximum and minimum absolute values of voltage to be applied to liquid crystal, and in the present liquid crystal display device, the voltage ranges for an auxiliary capacitance line drive signal, a video signal, and a common potential are equally maintained as low as from 0V to 4V, while inverting the common potential every scanning period and causing the potential of the auxiliary capacitance line drive signal to rise in the same direction as the common potential at the time of the fall of the scanning signal such that the potential is maintained until the next frame. With this configuration, it is possible to set the maximum absolute value of the voltage applied to the liquid crystal at about 5V, which corresponds to an effective value of the applied voltage, while setting the minimum value at about 1.5V, which is also an effective value of the applied voltage, thereby increasing the difference between the maximum and minimum values.

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： On a transparent electrically insulating substrate, formed are a scanning line, and a gate electrode of a switching element, further formed are a gate insulating film, a semiconductor layer, an n+-Si layer to be formed into a source electrode and a drain electrode. After the patterning of the foregoing structure, the dielectric film is formed, and the portion corresponding to the contact hole is removed by etching, and photosensitive resin is applied to form the interlayer insulating film. Then, the transparent electrode is extended from the pixel electrode over the switching element, whereon a conversion layer and a gold layer for use in electrode are vapor-deposited. In this structure, an increase in capacitor between the pixel electrode and the signal line can be suppressed by the interlayer insulating film, and the transparent electrode functions as a top gate and release excessive electric charge. As a result, excessive electric charge can be released effectively in the double gate structure while suppressing an increase in capacitor between the pixel electrode and the signal line.

摘要： In an active matrix substrate, a glass substrate is provided with TFTs having gate electrodes connected to scanning lines also provided on the glass substrate. The glass substrate is further provided with auxiliary capacitance lines, formed on the same layer as the scanning lines. Further, pixel electrodes connected to drain electrodes of the TFTs are formed on the same layer as signal lines connected to source electrodes of the TFTs. An insulating layer is provided between the layer forming the signal lines and pixel electrodes and the layer forming the drain and source electrodes. Since the insulating film is present between the signal lines and the scanning and auxiliary capacitance lines, influence on the auxiliary capacitance value can be reduced, as can a signal line capacitance value. As a result, even when the auxiliary capacitance value is increased, the signal line capacitance value remains small.
