Abstract
To improve viewing angle characteristics by varying voltage which is applied between liquid crystal elements. A liquid crystal display device in which one pixel is provided with three or more liquid crystal elements and the level of voltage which is applied is varied between the liquid crystal elements is varied. In order to vary the level of the voltage which is applied between the liquid crystal elements, an element which divides the applied voltage is provided. In order to vary the level of the applied voltage, a capacitor, a resistor, a transistor, or the like is used. Viewing angle characteristics can be improved by varying the level of the voltage which is applied between the liquid crystal elements.
