A color display device comprising:
- a substrate;
- a pixel structure demarcating a multiplicity of light-transmissive unit display regions formed on said substrate;
- and
- a color filter disposed on each of said unit display regions, covering only a part of each said unit display region and not covering a remaining area of each said unit display region, said remaining areas forming light transmissive areas without any color filter;
- wherein said remaining area and said part of each said unit display region define a first region and a second region, respectively, in which said first region is a region where white light is modulated and said second region is a region where light of a particular color, as defined by an associated one of said color filters, is modulated.
