<P>PROBLEM TO BE SOLVED: To provide a spacial light modulation system for obtaining smooth and high image quality without recognizing the image of a light shielding part such as a black matrix by an observer, and to provide a projector. <P>SOLUTION: The spacial light modulation system 110R has prism groups 210. When a distance from a reference face 901 to a flat part 920b is d, a wavelength of incident light is λ and a refractive index of a prism element is n, any one condition equation of d<0.95×λ/(2×(n-1)) or d>1.05×λ/(2×(n-1)) is satisfied. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
