    摘要: An electrophoretic display device includes unit cells each containing i) two sets of display electrodes and a collection electrode and ii) two kinds of translucent colored electrophoretic particles having charge polarities different from each other. The unit cells are constructed so that the two display electrodes are superimposingly disposed to display the stated display color by the principle of subtractive mixture of color stimuli of the colored electrophoretic particles present on the display electrodes. Three unit cells are adjacently disposed in a same plane to form a pixel, and combinations of colors of the two kinds of translucent colored electrophoretic particles in each of the three unit cells forming the pixel are respectively one of the three primary colors and a color which provides black by subtractive mixture with one of the three primary colors.

    摘要: A liquid crystal device is constituted by a pair of substrates each having thereon an electrode and a uniaxial alignment film, and a chiral smectic liquid crystal disposed between the substrates. At least one of the uniaxial alignment films is a film comprising an electroconductive polymer doped with at least two species of dopants, which preferably include a first type dopant capable of dedoping into the liquid crystal due to electric field application or diffusion, and a second type dopant substantially incapable of dedoping into the liquid crystal. The resultant liquid crystal device is alleviated with respect to voltage hysteresis and is suitable for gradational display.
