摘要： A liquid crystal display in which a reference signal main line, placed so as to connect reference signal lines to each other, is separated into an input main line and an output main line in an insulating state from each other. Then, a voltage application line from a voltage-application circuit for controlling the voltage of a reference signal is connected to the input main line and a voltage feedback line therefrom is connected to the output main line. Thus, it becomes possible to accurately detect minute voltage variations within a reference signal circuit and compensate for them.

摘要： It is an object of the invention to reduce a leakage low-frequency electric field from a panel section of a matrix type. In the case where a panel section has a usual current structure in which the panel section has a single common electrode elongating over the whole of the display region of the panel section, the maximum voltage difference of a reference signal supplied to the common electrode is defined to be 0.3678×x−0.6136 (wherein x is the area of the display region) or less. In the case where the panel section has the so-called counter source structure and a plurality of column electrodes, the maximum voltage difference of a reference signal supplied to the column electrodes is defined to be ax−b (wherein a=0.3565×y−0.6829, b=−0.0937y+0.7091, and y is a ratio of the area of all the column electrodes to the area of the display region) or less. In the case where a panel section has the counter source structure, the average area per unit length of one part of the column electrode opposed to a signal line is smaller than the average area per unit length of the remaining part of the column electrode other than the one part.

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.

摘要： A wave A1 is used as a signal inputted to a liquid crystal panel via an operational amplifier OP. The wave A1 is a superimposed wave made up of, for example, a first rectangular wave to be the base of a driving signal and a second wave capable of increasing respective amplitudes of the first wave in rising and falling directions. Because a wave A3 is superimposed, using the wave A1 as the driving signal of the liquid crystal panel surely results in increase in a quantity of charges with which respective pixels of the liquid crystal panel are supplied at early stages of writing, more than simply applying the wave A2 to the liquid crystal panel. Consequently, even when a charge supplying ability of a reference voltage line is considerably low, a desired charging quantity can surely be obtained in respective pixels within desired writing time, thereby preventing crosstalk having different degrees depending on a location even when a charge supplying ability for the respective pixels of the liquid crystal panel is considerably low.

摘要： A liquid crystal display device has a liquid crystal layer between a glass substrate and a counter substrate. A TFT and scanning lines which control the TFT are provided on the glass substrate. On the counter substrate, a gradation signal line which is connected to a counter electrode applying a voltage to the liquid crystal layer is provided opposite to the scanning lines. A sealing section for sealing the liquid crystal of the liquid crystal layer is provided while enclosing the display area between the glass substrate and the counter substrate. The sealing section has conductive particles. Upper contact pads connected to the gradation signal lines and lower contact pads on the glass substrate are electrically connected via the conductive particles. This realizes a liquid crystal display device with a smaller frame and makes the mounting compact in size without causing poor connection due to line breakage.

摘要： As a method of driving a liquid crystal display device, the average voltage of reference line drive voltages Vcom for AC-driving a liquid crystal is set higher than the average voltage of signal line drive voltage V0. Moreover, when displaying a plurality of gray scales, the respective voltages are set so that the average voltage of the signal line drive voltages is lowered with a decrease in a voltage difference to be applied to the liquid crystal as an absolute value. In a liquid crystal display device of an opposing signal line structure, a high-quality image display is achieved by compensating for the non-symmetry of the transmissivity of the liquid crystal with respect to positive and negative drive voltages to prevent flickering and image persistence.
