Abstract: 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.
