Abstract
In an information display system panel, color filters each having respective colors are arranged to an outer surface of a transparent substrate at an observation side having a refractive index n and a thickness d, in such a manner that an overlap area between the color filter and the pixel is set in a range of 50%-100% with respect to an area of the pixel, so that a portion between adjacent color filters having different colors, which is perpendicular to a tilt visual direction, is spaced at either one of an upper and lower sides and a right and left sides of the color filter; and a relation between a visual filed displacement I indicated by following formula (1), which is generated when the image displayed by the display media is viewed as a reflected light refracted at 45° with respect to a surface of the color filter, and LS and DS denoting a pixel pitch and a pixel space along a visual direction respectively, satisfies I≦0.5×(DS+LS);I=d×[sin2 θ/(n2−sin2 θ)]1/2 θ=45° formula (1).According to the invention, an information display panel which can prevent a color mixture with the adjacent pixel when viewed at a slant angle and can perform a color display having an excellent color …
