    摘要: A liquid crystal cell filled with a polymer-dispersed liquid crystal layer 15 comprising liquid crystal droplets 15.sub.1 dispersed in a polymer 15.sub.2 between a first glass base plate 11 with a first transparent electrode 12 and a second glass base plate 13 with a second transparent electrode 14, is placed between crossed Nicols formed by a first polarizer 16 and a second polarizer 17, with a backlight 18 situated on the outer side thereof, the diameter of the liquid crystal droplets 15.sub.1 is between 3 .mu.m and 100 .mu.m, and the liquid crystal molecules in the liquid crystal droplets 15.sub.1 are twisted to between 30.degree. and 180.degree.. The liquid crystals used have a dielectric anisotropy .DELTA..epsilon. which is negative when the frequency of the electric field is high and positive when the frequency is low, and by adjusting the dielectric anisotropy .DELTA..epsilon. via the frequency of the electric field it is possible to form liquid crystal droplets of a desired diameter.

    摘要: A liquid crystal display panel including at least two liquid crystal layers, and a color filter having two color portions. One of the liquid crystal layers includes solid regions and liquid crystal dispersing regions arranged adjacent to the solid regions. Picture electrodes are arranged on the first plate, on the liquid crystal dispersing regions, and on the solid regions, at positions corresponding to the color portions of the color filter. A common electrode is arranged on the second plate. The picture elements on the liquid crystal dispersing regions and on the solid regions are connected to the conductors on the first plate by connecting members extending through the solid regions. Therefore, the liquid crystal layers can be independently controlled.
