Abstract:
1. A color filter with a retardation layer comprising: a substrate; a colored layer comprising a plurality of rows of light transmissive patterns, whose thickness differs according to its color, formed on the substrate, a first retardation layer formed as one continuous layer, on the colored layer, made of a liquid crystalline polymer, having an optical axis perpendicular to a plane of the substrate so as to function as a C plate; and a second retardation layer formed on an opposite side of the substrate to a side with the colored layer formed, or between the substrate and the colored layer, having an optical axis parallel to the plane of the substrate so as to function as a positive A plate having a positive refractive index anisotropy, wherein a refractive index anisotropy of the second retardation layer in a visible light range becomes smaller with a shorter wavelength, and further wherein a total of a thickness of the colored layer and a thickness of the first retardation layer is constant, and the thickness of the first retardation layer differs according to a thickness of the light transmissive pattern.
