Liquid crystal display device and display system

A liquid crystal display device comprising:

• a first substrate;
• a second substrate opposite the first substrate;
• a liquid crystal layer between the first substrate and the second substrate;
• and
• an active area including:
• a plurality of first regions and a plurality of second regions distributed so as not to overlap the plurality of first regions, wherein
• each first region includes a switching element and is supplied with a grayscale signal via the switching element,
• each of the plurality of second regions does not include the switching element and is supplied with a common signal,
• each first region further includes a pixel electrode connected to a corresponding switching element in the first region,
• each of the plurality of second regions includes a transparent electrode, and
• the liquid crystal display device further comprises:
• an opposite electrode opposite the pixel electrodes and the transparent electrodes;
• a plurality of data lines extending in a column direction, each data line connected to a respective switching element of each first region to supply the grayscale signal to the first region;
• a plurality of scan lines extending in a row direction, each scan line connected to a respective switching element of each first region;
• and
• a plurality of auxiliary capacitor lines supplied with a signal of a substantially same potential as a potential of the opposite electrode.
