A color filter comprising a substrate, a red pixel, green pixel and blue pixel, each being disposed on the substrate, wherein a perpendicular optical retardation R<SUB>Rth </SUB>of the red pixel, a perpendicular optical retardation G<SUB>Rth </SUB>of the green pixel, and a perpendicular optical retardation B<SUB>Rth </SUB>of the blue pixel satisfy the following formulas (1) and (2): <?in-line-formulae description="In-line Formulae" end="lead"?>|(R<SUB>Rth</SUB>-B<SUB>Rth</SUB>)|-|(G<SUB>Rth</SUB>-B<SUB>Rth</SUB>)|>=0 (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>|(R<SUB>Rth</SUB>-B<SUB>Rth</SUB>)|-|(R<SUB>Rth</SUB>-G<SUB>Rth</SUB>)|>=0 (2)<?in-line-formulae description="In-line Formulae" end="tail"?> wherein R<SUB>Rth</SUB>, G<SUB>Rth </SUB>and B<SUB>Rth </SUB>represent, respectively, a product of a thickness [nm] of a pixel and a value obtained by subtracting a value of thickness-wise refractive index from an average value of an in-plane refractive index of each of these pixels.
