And a color bar group formed on the transparent substrate, wherein the color bar group is constituted by arranging color bars of a plurality of colors including at least a first color and a second color in a pattern shape in an orderly manner, The coordinate point of the first color is in an area surrounded by four points of (0.351, 0.649), (0.547, 0.453), (0.380, 0.506), and (0.433, 0.464) on the xy chromaticity diagram, The coordinate points are located in a region surrounded by four points of (0.125, 0.489), (0.112, 0.229), (0.270, 0.407), and (0.224, 0.242) on the xy chromaticity diagram, And the transmission spectrum of the second color bar have separated peak tops, respectively. |
