Patent ID: 7522252

Claim:
A display device comprising: two substrates; a display medium layer provided between the two substrates; a plurality of picture elements, each of which includes an associated portion of the display medium layer and which is made up of a first group of picture elements, a second group of picture elements and a third group of picture elements, the first, second and third groups of picture elements transmitting light rays representing three different colors, respectively; and a plurality of spacers, which are provided at predetermined relative positions for selected ones of the picture elements, the selected picture elements consisting of a number of picture elements belonging to the first group, a number of picture elements belonging to the second group, and a number of picture elements belonging to the third group, the spacers being arranged such that in the selected picture elements, the smallest number of picture elements of the first, second or third group is at least 80% of the largest number of picture elements of the first, second or third group; wherein the picture elements are arranged at a predetermined pitch px in a row direction and at another predetermined pitch py in a column direction, respectively, and wherein the spacers include a spacer set consisting of five spacers with no other spacers therebetween, wherein the spacer set of five spacers consists of a first pair of spacers, a second pair of spacers, and a central spacer, the spacers of the first pair being separated from each other by a distance of m·px (where m is an integer equal to or greater than 2 but is not a multiple of 3) in the row direction, the spacers of the second pair being separated from the spacers of the first pair by a distance of n·py (where n is a positive integer and a multiple of 2) in the column direction, the central spacer being separated from the spacers of the first pair by a distance of m·px/2 in the row direction and by a distance of n·py/2 in the column direction, respectively.
