Abstract

A display device of the present invention switches between two displays, a main panel display and a sub-panel display, by using one driver IC. Liquid crystals having different optimal driver voltages are used in the main panel and the sub-panel, and the optimal driver voltage for the panel in which display is to be performed is output. A driver voltage that is higher or lower than the optimal driver voltage is applied to the display panel where display is not to be performed, and the entire display thereof displays a single color. Display content of the panel on which display is not to be performed cannot be identified.
