Patent ID: 7965353

Claim:
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 Rth of the red pixel, a perpendicular optical retardation G Rth of the green pixel, and a perpendicular optical retardation B Rth of the blue pixel range from −10 nm and +10 nm and satisfy the following formulas (1) and (2): |( R Rth −B Rth )|−|( G Rth −B Rth )|≧0 (1) |( R Rth −B Rth )|−|( R Rth −G Rth )|≧0 (2) wherein R Rth , G Rth and B Rth 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.
