1. A multi-primary-color display device comprising:
- a plurality of pixels each including a first subset including red, green and cyan subpixels and a second subset including yellow and blue subpixels;
whereinin each of said plurality of pixels, the subpixels included in the first subset are arranged in series in one direction, and the subpixels included in the second subset are arranged in series in the same direction as the subpixels of the first subset; and
supposing achromatic colors to be represented by the first and second subsets are called a first achromatic color and a second achromatic color, respectively, a ratio of a difference in luminance between the first and second achromatic colors to a sum of maximum luminances of the first and second achromatic colors is equal to or smaller than about 15% and a difference u′
v′
in chromaticity between the first and second achromatic colors is equal to or smaller than about 0.100.

Abstract
A multi-primary-color display device includes a number of pixels, each of which includes a first subset including red, green and cyan subpixels and a second subset including blue and yellow subpixels. In each pixel, the subpixels included in the first subset are arranged in series in one direction, while the subpixels included in the second subset are arranged in series in the same direction as the subpixels of the first subset.

11. A multi-primary-color display device comprising:
-
a plurality of pixels each including a first subset including red, green and cyan subpixels and a second subset including yellow and blue subpixels;
whereinin each of said plurality of pixels, the subpixels included in the first subset are arranged in series in one direction, and the subpixels included in the second subset are arranged in series in the same direction as the subpixels of the first subset; and the subpixels of the respective pixels are arranged in a matrix, and supposing an achromatic color to be represented by not only one of the first and second subsets but also subpixels that are adjacent to the one subset is called a first achromatic color and an achromatic color to be represented by the other subset is called a second achromatic color, a ratio of a difference in luminance between the first and second achromatic colors to a sum of the maximum luminances of the first and second achromatic colors is equal to or smaller than about 15% and a difference u′

12. A multi-primary-color display device comprising:
-
a plurality of pixels each including a first subset including red, green and cyan subpixels and a second subset including yellow and blue subpixels;
whereinin each of said plurality of pixels, the subpixels included in the first subset are arranged in series in one direction, and the subpixels included in the second subset are arranged in series in the same direction as the subpixels of the first subset; and the subpixels of the respective pixels are arranged in a matrix, and supposing an achromatic color to be represented by not only one of the first and second subsets but also subpixels that are adjacent to the one subset is called a first achromatic color and an achromatic color to be represented by not only the other subset but also subpixels that are adjacent to the other subset is called a second achromatic color, a ratio of a difference in luminance between the first and second achromatic colors to a sum of the maximum luminances of the first and second achromatic colors is equal to or smaller than about 15% and a difference u′

13. A multi-primary-color display device comprising:
-
a plurality of pixels each including a first subset including red, green and cyan subpixels and a second subset including yellow and blue subpixels;
whereinin each of said plurality of pixels, the subpixels included in the first subset are arranged in series in one direction, and the subpixels included in the second subset are arranged in series in the same direction as the subpixels of the first subset; and when one of the pixels represents an achromatic color, an upper limit of luminance of at least one of the subpixels included in the first and second subsets is defined to be lower than a luminance of each of the at least one of the subpixels corresponding to a highest grayscale.
