摘要： A driving method for an image display apparatus is disclosed. The image display apparatus includes an image display panel including a plurality of pixels each including first, second, third and fourth subpixels and arrayed in a two-dimensional matrix. A signal processing section determines an expansion coefficient based on a saturation value and a maximum value of brightness in an HSV color space expanded by addition of a fourth color to three primary colors. First to third correction signal values and a fourth correction signal value are determined based on the expansion coefficient, first to third subpixel input signals and first to third constants. A fourth subpixel output signal is determined from the fourth correction signal value and a fifth correction signal value determined from the expansion coefficient and the first to third subpixel input signals and output to the fourth subpixel.

摘要： A display includes a polarizing member and a reflective display element behind an EL element. The EL element self-emits light to display information and doubles as a display-use light source for the reflective display element. In a sufficiently bright environment, ambient light enters a liquid crystal layer after passing through a frontal substrate of the reflective display element, and is reflected from a metal electrode to produce displays. In addition to the direct light from the EL element, light that enters the liquid crystal layer is simultaneously used. In a dark environment, the EL element emits light, and displayed contents are visible owing to the reflection from the metal electrode as well as directly exiting light. The structure makes it possible to provide a novel type of display that allows a user to select one of various display modes at his/her own discretion according to surrounding conditions and that also shows information in a clearly visible fashion, be it outdoors under clear skies or in a dark place, without giving up their thin, lightweight features.

The liquid crystal display has a driving substrate on which transparent pixel electrodes are formed; a counter substrate on which a counter electrode is formed; and a liquid crystal material disposed between the driving substrate and the counter substrate, molecules of the liquid crystal material being oriented orthogonally to the substrates. The driving substrate has pixel capacitors and pixel transistors formed thereon, the pixel capacitors being disposed under the pixel electrodes, the pixel transistors acting to write signal voltages to the pixel electrodes and to the pixel capacitors. The pixel electrodes have slits formed over the pixel capacitors to orient the molecules of the liquid crystal material orthogonally and in a split manner. Each of the pixel capacitors has an electrode for reflecting light and forms a reflective region. Thickness of portions of the liquid crystal material present in the reflective regions is greater than half of thickness of portions of the liquid crystal material present in transmissive regions other than the reflective regions.

摘要： In a normally black mode liquid crystal display, the liquid crystal display and the method prevents the light leakage arising from existing the step for adjusting the thickness of the liquid crystal layer between the reflective electrode and the transparent electrode and that high contrast displaying can be possible. The interval adjustment layer is formed between the first substrate that the reflective electrode is formed in the reflective region and the transparent electrode is formed in the transmissive region, and the second substrate that is fixed at predetermined interval from the first substrate. This interval adjustment layer is adjuster of the thickness of the liquid crystal layer in the reflective region on the second substrate, and the thickness of the liquid crystal layer in the reflective region is preferable to be set approximately the thickness of the liquid crystal layer of the transmissive region.

摘要： A method of aligning a liquid crystal includes a step of fixing on a hot plate and heating a liquid crystal cell in which a liquid crystal composed of a ferroelectric liquid crystal material sealed between electrode substrates respectively having alignment films having applied thereto a uniaxial alignment by rubbing. According to the described method, a pressure is applied to the liquid crystal cell by a roller, and a portion subjected to an application of pressure is moved by moving the roller. Further, the liquid crystal is heated within a temperature range between a phase transition temperature of SmA phase SmC* phase and a temperature 10° C. below the phase transition temperature, and the portion subjected to an application of pressure is moved in the same direction as the rubbing direction, thereby achieving the C2 orientation at higher yield. Within the described temperature range, by moving the portion in an opposite direction to the rubbing direction, a C2 orientation can be always achieved at high yield (almost 100%). As a result, the C2 orientation can be surely achieved in the liquid crystal display element with ease.

摘要： An electrode substrate is placed on a stage heated at temperature in a range of from 50.degree. to 200.degree. C. in such a manner that an alignment film of the electrode substrate faces upwards. Thereafter, a rubbing treatment is applied by a roller having the rubbing cloth wound therearound by moving a stage while rubbing the surface of the alignment film by rotating the roller in a state where the electrode substrate is sufficiently heated. Here, as the alignment film is softened by the described heat treatment, the rubbing process is facilitated. This permits a uniform C2 orientation without defects to be achieved in smectic liquid crystals.
