Patent ID: 7102708

Claim:
A color filter substrate comprising: a base member; a color filter layer, which is provided on the base member and which is made up of a first group of color filters, a second group of color filters and a third group of color filters, the first, second and third groups of color filters transmitting light rays representing three different colors, respectively; a plurality of spacers, which are provided at predetermined relative positions for selected ones of the color filters, the selected color filters consisting of a number of color filters belonging to the first group of a first color, a number of color filters belonging to the second group of a second different color, and a number of color filters belonging to the third group of a third different color, so that some but not all of the color filters of each of the first color, second color, and third color are provided with spacers, the spacers being arranged such that in the selected color filters, the smallest number of color filters of the first, second or third group is at least 80% of the largest number of color filters of the first, second or third grouping; and wherein the color filters 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.
