Abstract
A multilayered liquid crystal display device includes a front substrate, a rear substrate and at least one intermediate substrate interposed therebetween, respective spaces being formed between the intermediate substrate and the front substrate, and between the intermediate substrate and the rear substrate. Liquid crystal layers are in the spaces between the substrates so that the display surfaces provide an overall display. Intersecting signal and scanning electrodes are arranged on opposed mutually facing surfaces of the intermediate and rear substrate and of the intermediate and front substrate. Color layers are arranged in an optical path corresponding to the intersecting portions of the signal and scanning electrodes, but on the opposite side of the intermediate substrate on which the associated intersecting signal and scanning lines are located. The color layers are not interposed between their associated intersecting signal and scanning electrodes. The display is arranged in adjacent sections, each adjacent section being on opposite sides of the intermediate substrate, thereby producing a uniform display surface.
