Display device and information terminal

A display device comprising:

• a back light as a light source for illuminating a predetermined surface from a back side thereof;
• color image reproducing means arranged on said predetermined surface illuminated by said back light, for outputting a color image synthesized with three primary colors by controlling amounts of transmission of the three primary color lights in respective two dimensional areas corresponding to an image signal;
• and
• monochromatic image reproducing means arranged on said predetermined surface illuminated by said back light, for outputting a monochromatic image by controlling an amount of transmission of light in respective two dimensional areas corresponding to an image signal,
• wherein said color image reproducing means and said monochromatic image reproducing means comprise a display electrode group composed of three kinds of rod like color electrodes for independently controlling displays of the respective R, G and B colors and one kind of rod like monochromatic display electrode for controlling a display of a monochromatic image and are repeatedly arranged in predetermined directions on a common plane, a gate electrode group composed of a plurality of parallel gate electrodes arranged in a direction crossing the directions of said respective electrodes constituting said display electrode group with a predetermined interval and liquid crystal filling a space between said display electrode group and said gate electrode group.
