1. A liquid crystal display device comprising:
a first liquid crystal display panel in which a first main pixel including a plurality of subpixels of different colors is arranged in a matrix in a predetermined first direction and a predetermined second direction perpendicular to the predetermined first direction, the first liquid crystal display panel displaying a color image; and
a second liquid crystal display panel that is positioned on a side, opposite a surface of an observer side, of the first liquid crystal display panel and overlaid on the first liquid crystal display panel, includes a second main pixel corresponding to a plurality of the first main pixel, the second liquid crystal display panel displaying a monochrome image, wherein
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,
the plurality of light shields is arranged in a staggered manner,
the light shields positioned within one set of the regions, formed from the regions adjacent to each other, forms one set of the light shields, and
the one set of light shields equally blocks, for each color, light incident on the subpixels.
