PURPOSE:To execute a black-and-white display being free from coloring by providing a liquid crystal cell for applying a voltage to a liquid crystal layer and an optical anisotropic body, so that at least one of a refractive index dispersion of the liquid crystal cell and the optical anisotropic body, a refractive index anisotropy and layer thickness becomes different. CONSTITUTION:The title element is provided with a liquid crystal cell 3 having a means for applying a voltage to at least a part of a liquid crystal layer 6, and at least one layer of optical anisotropic body 2, and at least one of a refractive index dispersion of the liquid crystal cell concerned 3 and the optical anisotropic body concerned 2, a refractive index anisotropy and layer thickness is different. An oriented film 9 is formed on the opposed faces of the respective upper substrates 7, 11 and the respective lower substrates 8, 12 of the liquid crystal cell (A cell) 2 being an optical anisotropic body and the liquid crystal cell (B cell) 3 for executing a display, and brought to rubbing processing (orientation processing). A transparent electrode 13 is formed on the opposed faces of the upper substrate 11 and the lower substrate 12 of the B cell 3, and the oriented film 9 of the B cell 3 is formed on the transparent electrode 13. In such a way, the external appearance of the electro-optical element becomes a color being similar to black and a color being similar to white, in a state that a voltage is not applied, and in a state that a voltage has been applied, respectively, and a black-and-white display of a good contrast is obtained. |
