摘要： A liquid crystal display device having a back side light source, which can perform displays of both a transmissive type and a reflective type, employs interference filters formed with a multilayer film 18, 19 and 20 as color filters to be used for color display. The back side light source is switched off in use as a reflective type display. The display in the liquid crystal display device can be inverted to a negative. The normal direction of the multilayer film of the interference filter may differ from the normal direction of a substrate.

摘要： In a ferroelectric liquid crystal panel, the switching current of spontaneous polarization is detected from the difference between the current supplied to a selected pixel and the constant multiplication of the current supplied to a non-selected reference pixel, and when the amount of switched spontaneous polarization reaches a desired gray scale level, the applied voltage is changed so that even if any nonuniformity is involved within the panel, a uniform analog gray scale display can be realized.

摘要： A driving method in accordance with the present invention permits the simple time sharing driving of a ferroelectric liquid crystal matrix panel at high scanning frequency and high multiplexing ratio. A predetermined pulse is applied to a scanning electrode when another scanning electrode is selected to reset the pixel. The pixel is inverted or kept by the action of a pulse applied to the pixel when selected and, under this condition, a desired brightness is written in a short scanning period. Besides, the representation of a number of grey levels is obtained by multiple scanning at reset timing varying with the scanning.

摘要： In a method of driving an optical modulation device via scanning lines and signal lines a "selection period" of each scanning line is divided into at least four division periods. A voltage applied to a pixel allows the pixel to become a first stable state of bistable states of the pixel during third and second division periods from the last division period, and to either become a second stable state of the bistable states or hold the first state during the last division period. The scanning lines are scanned sequentially while at least two sequential scanning lines thereof may be applied with a same selection voltage at the same time, thereby reducing a time required for rewriting all pixels.
