Abstract: Disclosed is a liquid crystal shutter that uses as a shutter a liquid crystal panel constructed by sandwiching DHF liquid crystal between a pair of substrates provided with one or more pixel electrodes and one or more counter electrodes, wherein a driving waveform for the panel has a write period comprising two subfields. In each of the subfields, a single pulse is applied to a pixel, the single pulse applied in one subfield being opposite in polarity to the single pulse applied in the other subfield. On the other hand, a constant voltage of 0 V or close to 0 V is applied to the pixel during a period in which neither of the single pulses is applied.

Abstract: The present invention relates to a liquid crystal unit having a liquid crystal panel (2) that has an antiferroelectric liquid crystal or ferroelectric liquid crystal sandwiched between a pair of substrates (23a, 23b), and a backlight (1) for illuminating the liquid crystal panel (10). For improving image quality of a display screen, an amount of light output from the backlight is adjusted according to a change in conical angle, a change in temperature of use of the liquid crystal panel (10) or temperature at which the liquid crystal panel is usable, a change in polarization reverse current, a change in transmission light, or the like. An angle at which two sheet polarizers (21a, 21b) are arranged is adjusted according to the change. According to the present invention, a display screen with good image quality can be provided.

Abstract: The present invention attempts to overcome irregular display deriving from a variation in resistance among wiring electrodes or periodicity of resistances. At least two output terminals of a driving IC chip and one electrode are linked, whereby the width of a wiring electrode can be made twice larger or more. Consequently, the variation in resistance among wiring electrodes is minimized. Furthermore, if driving IC chips are placed at both ends of belt-shaped electrodes, a difference in voltage between the right and left sides of a display screen will not occur. A difference in display state between the right and left sides of the display screen can be resolved (FIG. 3).
