Color image display device, color filter substrate, color pixel array substrate, and electronic device

A color filter substrate comprising:

• an end portion unit pixel formed in an edge portion of a display region in which a color image is displayed and including a plurality of kinds of end portion sub-pixels which correspond to a plurality of kinds of primary colors respectively in a one-to-one relationship;
• and
• an inner unit pixel formed in an inside of said display region with respect to said end portion unit pixels and including a plurality of kinds of inner sub-pixels which correspond to the plurality of kinds of primary colors respectively in a one-to-one relationship,
• wherein a relative area proportion of said end portion sub-pixels that correspond to the primary colors respectively in a one-to-one relationship is set equal to that of said inner sub-pixels that correspond to the primary colors respectively in a one-to-one relationship;
• and
• wherein said plurality of kinds of said end portion sub-pixels is arrayed in accordance with a position or a shape on an outer edge of said display region, an array direction of said plurality of kinds of said end portion sub-pixels and an array direction of said plurality of kinds of said inner sub-pixels configured to intersect each other.
