摘要： When a photopolymerization compound (molecular weight: not less than 300) having at least two ultraviolet light sensitive portions in its molecular structure is mixed with ferroelectric liquid crystal and an exposure to ultraviolet light is performed, a continuous structure is formed over almost whole length between two glass substrates, and a continuous twisted structure is formed between the glass substrates in the state of liquid crystal molecular orientation. Before the exposure to ultraviolet light, the photopolymerization compound does not exhibit satisfactory compatibility with the ferroelectric liquid crystal to be mixed, but exhibits phase separation in the mixed state. The ferroelectric liquid crystal has a bookshelf layer structure.

摘要： A display control method of a liquid crystal displaying apparatus for driving a liquid crystal panel comprising two substrates, and a liquid crystal layer therebetween. The driving means includes: pixel electrodes each corresponding to a pixel; and for time-division, emitting an LED (Light Emitting Diode) array for red, green, and blue as a back light within each display period, in synchronization with the on/off operation of the pixel electrodes. Each display period is divided into four. The LEDs in the LED array emit red, green, and blue lights in one of the divided periods. Then, one of the three colors is emitted again. This method solves the problem of the conventional control method for performing time-division color display in a liquid crystal displaying apparatus; namely, the insufficient emission intensity of LEDs makes the intensity of the entire liquid display apparatus insufficient, such that white is seen as somewhat grayish white to the human eye.

摘要： In a field sequential display method the light emission intensities of the luminous colors are controlled to realize a plurality of color reproduction regions having different areas and make the color purity variable. In the case of high-resolution image display, a first control method is adopted in which in synchronism with the input of the pixel data of one of the luminous colors, the light of the one of the luminous colors is emitted and the lights of the other luminous colors are not emitted. In the case of coarse image display, a second control method is adopted in which in synchronism with the input of the pixel data of one of the luminous colors, the light of the one of the luminous colors and the lights of the other luminous colors are emitted. By the second method, the color purity is slightly decreased to suppress the visual irritation.

摘要： In a liquid crystal display device, one or a plurality of partition walls adhering to the two substrates are provided in a region between the adhesive member for sealing the peripheral portions of the two substrates and a display region located inside the adhesive member so as to reduce stress applied to the liquid crystal substance. Even when stress is applied to the liquid crystal substance in the peripheral portion of the substrate, the stress is reduced by the partition wall and is not transmitted to the display region on the opposite side of the partition wall. Therefore, even when a crack occurs in the peripheral portion of the substrate due to the stress, the propagation of the crack is stopped by the partition wall, and the crack does not enter the display region.
