ABSTRACT:
A color filter substrate includes a base member, a color filter layer, and spacers. The color filter layer is provided on the base member and made up of first, second and third groups of color filters, which transmit light rays representing three different colors, respectively. The spacers are provided at predetermined relative positions for selected ones of the color filters. The selected color filters consist of color filters belonging to the first group, color filters belonging to the second group, and color filters belonging to the third group. The spacers are 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 group.
