摘要:
A recording material made of an alloy capable of exhibiting different spectral reflectances at an equal temperature, depending on a heating-cooling cycle to which the alloy is subjected. The alloy can possess in solid state different crystal structures at a first temperature higher than the room temperature and at a second temperature lower than the first temperature but not lower than the room temperature. A part of the surface of the alloy exhibits, as a result of being quenched from the first temperature, a crystal structure which is different from the crystal structure at the second temperature, while the other part possesses the crystal structure at the second temperature, so that these two parts exhibit different spectral reflectances. Using this recording medium, it is possible to record, reproduce and erase information by means of, for example, laser beams.

It is possible eliminate a fringe pattern produced at the time of incidence of polarized light of a light distribution control element, in which stray light derived from outside unnecessary light in a liquid crystal display apparatus or the like can be effectively reduced, and bright, wide viewing angle characteristics can be achieved when the display is viewed at any angle by an observer. In a light distribution control element constituted of a transparent base member, an array of a plurality of micro-lenses (transparent beads) densely arranged on the transparent base member and a light absorbing layer having very small opening portions substantially at focal positions of the micro-lenses, the transparent base member is constituted of a transparent body which is substantially isotropic optically or a transparent body having uniaxial optical anisotropy.

A liquid crystal display has pixels in domains surrounded by data signal lines and scanning signal lines. Each of the pixels has a voltage holding device for a positive polarity and a voltage holding device for a negative polarity, two lines of voltage holding interconnections which always apply a maximum voltage and a minimum voltage of a voltage applied to the data signal lines formed for holding the voltage, and a switching device for switching between outputs from the voltage holding devices. One time or more within one frame time period thereof, the switching is performed between the voltage holding device for a positive polarity and the voltage holding device for a negative polarity.
