Abstract
A liquid crystal display device displays an image by stacking a plurality of liquid crystal panels, and by controlling a light transmittance with voltage application to liquid crystal of each panel, wherein during execution of voltage application to the liquid crystal of one of the panels, a voltage to the liquid crystal of the other panel serves as a non-display voltage. No image is displayed simultaneously on the two or more stacked liquid crystal panels. In the liquid crystal panel to which no voltage is applied and on which no image is displayed, the longitudinal axial direction of liquid crystal molecules coincides with the polarizing axial direction of polarizers, or is orthogonal to the polarizing axial direction; therefore, no influence is exerted on the overall double refraction, and the overall voltage-transmitted light intensity characteristic corresponds to the sum of the voltage-transmitted light intensity characteristics of the respective panels.
