Abstract: A liquid crystal display device includes a first liquid crystal display panel in which a first main pixel including subpixels is arranged in a matrix, and that displays a color image, and a second liquid crystal display panel that includes a second main pixel corresponding to a plurality of the first main pixel, and that displays a monochrome image. The second main pixel is divided into a plurality of regions, and has pixel electrodes disposed in the plurality of regions and a plurality of light shields. At least a portion of the plurality of light shields is formed from a switching element that connects to each of the pixel electrodes, and the plurality of light shields is arranged in a staggered manner. The light shields positioned within one set of the regions formed from adjacent regions forms one set of the light shields.

Abstract: A liquid crystal display device includes a first liquid crystal display panel that displays a color image, a second liquid crystal display panel that displays a monochrome image, and a display controller that controls the display of the first liquid crystal display panel and the display of the second liquid crystal display panel. The display controller switches the display of the second liquid crystal display panel between a monochrome display that displays a monochrome image and an all-white display. In a state in which the display of the second liquid crystal display panel is the monochrome display, when a response time between predetermined gradations is greater than or equal to a predetermined first response time, the display controller switches the display of the second liquid crystal display panel from the monochrome display to the all-white display.
