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： 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.

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： Data-line inspection-use switching elements for switching the supply of inspection-use display signals are individually connected to a plurality of data lines, and scanning-line inspection-use switching elements for switching the supply of inspection-use scanning signals are individually connected to a plurality of scanning lines. The data-line inspection-use switching elements connected to the data lines are connected to an inspection-use display signal line for supplying the inspection-use display signals to the data-line inspection-use switching elements. Meanwhile, three data-line inspection-use control signal lines for inputting control signals for switching on/off the data-line inspection-use switching elements are provided in correspondence with the display colors. It is thus possible to provide an active-matrix-type liquid crystal display panel which enables an inspection with higher accuracy by performing a monochromatic display, without increasing unnecessary regions and increasing processes and defective units by cutting such regions, and enables the prevention of the outflow of the defective units and the reduction of the production cost.

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： A method of driving a display apparatus including a screen which has pixels arranged in a matrix applies a scanning signal to scanning signal lines connected to the pixels and thus selects each line to scan the screen and also supplies a data signal to those pixels on the selected line via data signal lines, so as to produce a display. Under these conditions, after the screen is scanned twice or more, there is provided a idle period T2 in which all the scanning signal lines are caused to be in a non-scanning state for a period longer than a scanning period T1 in which the screen is scanned once.

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.
